Love you guys's products and videos. Thank you and keep em coming. God bless and happy shooting.

Your video should display a chart of recommended buffer weights to the various combinations of barrels sizes/complete uppers BCA produces.Even better. you could provide the chart on your website.

Tungsten is more dense than steel, therefore it provides more mass per unit volume than steel. A 1x1x1" cube of tungsten will weigh more than a 1x1x1" cube of steel. Here on earth or anywhere in the universe their mass is different.

That chain is straight outta the late 90s early 00s. : P

Great video. It was very informative. One thing that could help is a chart or table that lays out what buffer would work with common barrel lengths and calibers. Thanks.

Thank you so much for breaking the purpose and function and types of buffers. I'm doing my first AR build and was stuck at the buffers and what I should be considering. Thanks for you help.

Great info thanks for sharing when I built my first AR that part was so confusing so I had a friend of mine that shot AR’s for a long time so he gave me one that he felt was right and it worked great for me and I use it for my 300 blackout and my 350 legend and It works great no problem thanks for sharing

Thank goodness for you. I've been looking for days for an explanation

just picked up a 762 upper, super stoked to get her mounted up

Thank you for the great explanation… building out 2 new ARs with different configurations.

Thanks, my brother. Excellent schooling!

It just "clicked" I know what I need. Thanks BCA! A rifle length buffer in a carbine weight.

Greetings from Germany. I have several ARs in 5.56 with Barrel lengths between 14.5 and 10.5. I run all of them suppressed and with H2 Buffers and they all cycle flawlessly.

Love a video that is straight and to the point!

lighter buffer for 300 BO subsonic. My 300 BO with 10.5" barrel and side charge functions flawless on supersonic rounds but subsonics will short stroke. Once I get my health back up to par, I am wanting to setup a 350 upper for deer and pigs.

The separate weights in the buffer not only give a little hesitation on the backstroke, but also counter bolt carrier bounce when slamming home, which is the main purpose of the buffer.

Good information. Thank you.

Thank you for sharing that. I'm learning a lot running through your videos. i just ordered one of your uppers, and am looking forward to play time.

Very informative thank you

This was so helpful. I recently got a 10.5 and it kept jamming. Never thought about the butter system being a huge factor. Thank you 🙏🏼🙌🏼

Good & informative video 👍

Gas port size, barrel size, and whether shooting suppressed, also play into which buffer weight you should use. I have a short 10.3” with a larger .070 gas port, that uses an h2 when suppressed and unsuppressed.

Love my 10.5 AR pistol. Just installed the H2 buffer. Going shooting this weekend.

Im loveing my bear creek ar thank you i ended up getting 2 one for dad i put a scope on mine he went open sights great rifle on problem i had after a 100 rounds my bolts were coming loose i took them out put a lil threat lock on them havant moved since

I ordered a 7.62 side charger from you all. I think I made mistakes like the lower I bought elsewhere being a carbine and not a heavier weight. But I say that to say, thank you for this video and your other videos. I'm new to the AR 15 as a buyer, but not new to guns. I'm glad I bought from you guys especially if it helps more videos being made.

Great video

Good video......Thanks

adjustable gas block or a BCG with an adjustable gas port can give more leeway on choice of buffer weight as well AND open the range of different grains of ammo.

Always pick H2 or heavier. If you have a silencer then pick the heaviest

Thanks brother, I bought a 7.62 side charging upper from BCA. Dropping it in my 5.56 lower. Looks like i should pickup an H1.

Nice. What about different springs?

This should really get worked into a high school physics class. It is a fantastic example of different types of energy transfer and Newton's laws.

Great info. But what about others. Strike industries short buffer flat wire set, or the Armaspec stealth recoil spring system. Multi spring shock system. Building for 10.5 side charger

Really surprised this dude missed at least SIX major points - 1) the size of the gas port in the barrel (how much gas gets out) 2) the size of the gas port in the gas block (metering how much gas gets through to the gas tube) 3) the length of the gas system (pistol, carbine, mid, intermed, rifle) 4) the length of the barrel and resulting dwell time 5) whether you are shooting suppressed or unsuppressed and 6) what type of ammo you are shooting (hot NATO loads vs. cheap low power steel case). All these impact cycling, reliability, feel, and parts wear and factor into choosing the right buffer. And there is wayyyy to much mixing and matching of parts going on in the community for any hard and fast rules espoused by one dude, you just have to figure out the right buffer and spring weight (and possible change to an adjustable gas block) on your own based on what you've assembled in your build in order to get it to run properly for what you are shooting. And btw, to keep the cost and price down, most manufacturers include a cheap carbine buffer (3 steel slugs vs. more expensive tungsten plugs) in the rifle - that doesn't mean it's the right answer, just the cheap answer. As a result, his massive oversimplification is misleading and wrong. Probably shouldn't be speaking on behalf of any manufacturer, but at least we know why Bear Creek is bottom tier.

What would you recommend using a pistol lower with a folding adapter

I am just starting to learn more about AR's, after owning and shooting them for years (bought as complete rifles) LOL these videos really make me want to buy your products for my planned build, as you are saving me a lot of headache figuring this all out... Now I'm just waiting for you to have some .223 complete uppers w/BCG, in 18" length, in stock... (it is the week after X-mas/ New Years as I write this, so I assume you are playing "catch up" on production)

What buffer would you recommend for your 18” barrel 7.62x39?

Good to see Hawkeye still working after endgame

Thanks for the heads up, I had purchased a Geiselle super 42 comes with H1 buffer and I can't fire 223 now only 556 so I guess I'm stuck with 556

Great video.. Quick question.. what buffer I need for a 7.5 in or 7in 7.62x39 AR upper. To work with a FRT trigger..... asking for a friend. 😅

What is the correct buffer weight for your .308 20” rifle length upper in a 6 position adjustable stock tube?

What about A5 length buffers& springs?I'm 6'6"&run vltor A5 buffer tube with h1 on both of my 350legend uppers 16"&18"with kvp linear comps- really smoothed out the recoil!Also run giessiele super43 springs &h1 buffers on my 7.62x39 pistols 7.5"&10.5"& they shoot like a dream! Able to fire accurate one handed with a sling support with red dots!all g2 uppers-just sent back my last rear charging!LOVE THE NEW HANDGUARDS! Just got new 7.5"g2 7.62x39-OMG SO MUCH FUN &CHEAP TO SHOOT!Capt J

I have a 458 socom 16" barrel with side changing handle. What do you normally recommend for a buffer weight?

What should I use for a 10.5 inch ar pistol 5.56 in your opinion????

Any thoughts on the crushed tungsten powder type buffer weights?

Hi thanks for posting the video I took my ar10 out today but I noticed my ar was short stroking. It was extracting the cartridge but it wasn’t allowing the round to come up. Thanks again for the video I’m going to switch to a lighter buffer tube

10.5 300acc. Pistol length gas tube. What would your recommendation be for Rubber City titanium ultra light BCG. Has H1 now but seems to recoil more than standard. Original BCG weighed 11oz vs 5.6oz for Rubber City

what buffer do you recommend for your 7.5" 7.62x39 side charger pistol upper?

What buffer would be considered for 16" 300 blackout build?

what would be ideal for a 20" Colt Match Hbar?

Great video. Am I correct in assuming if you have a lower with a fixed, A2 stock mounted, you use a traditional "rifle" buffer no matter what barrel and gas length you have on top? Thanks!

Tungsten does not have the same mass as steel. If it did it would weigh the same for equal volumes. Mass is equal to density * volume. The densities are different so the mass is different.

What buffer would be best for an AR that is 9mm with a 3 inch barrel? My upper came with a 7.8oz buffer and it shoots perfect in semi but once it’s switched into auto it shoots, ejects the casing, new round is chambered but trigger is dead/hammer not reset. What would my issue be? Do I need a lighter buffer?

I'm building with 18" with rifle length gas tube what do you recommend (5.56)

I have a h3 buffer in my carbine length ar15 16 inch barrel way over gassed now I get correct ejection pattern before I was getting around 2 o'clock ejection path

So for a mid length gas system with a 16 inch barrel what should I use??

I like your Ink. Thanks for the video. RLTW

I’m building a 7.5” .556 with 1:7 twist what buffer weight should I use?

What would be best buffer weight for my new BCA 16” 7.62x39? Thanks

Follow up to my question. FYI I am using my lower for a 300blk 10.5” barrel

I’m building my first AR 15 and I want to go with the Daniel Defense buffer tube and buffer/spring . Not sure if that’s a good idea ? My barrel going be 16” mid length gas system. At first I was going go with a H3 Carbine buffer with carbine length spring

Been looking for 10.5 inch wmr. Anytime being available again?

So of I'm getting hammer follows on a rifle length system, What should I do with my buffer spring and buffer?

16" rifle length gas system, running suppressed, running binary trigger... any recs?

Can I use a Rifle length buffer tube with a carbine gas system/completed upper I got from BCA? Carbine is going to have higher gas pressure right, so wouldn’t that be compatible with a rifle length buffer tube? Still learning how all this works 🤷🏻‍♂️🙏🏽

Ive seen MANY people say the opposite of what your saying for 7.62x39: 16 inch = Carbine - H2 10.5 Inch = H2 7.5 or Below = H2 - H3 Seems the smaller you go the more gassy and violent the action becomes. The heavier weight help balance it all out. YOU SAID to use a carbine weight on a 10.5 or below 7.62x39 pistol? That would seem to be absolutely violent and break parts more frequently. Including nothing suppressing all the gas (ive had a 7.5 and in "1" shot the gas was buring my eyes). The 10.5 was gassy but not as extreme as the 7.5. Those where both with a H2 buffer. The recoil however was very good even on a 10.5 with no brace (cheek method). The 7.5 with the H2 was very violent in gas and recoil. Was so bad i didnt even want to continue shooting.

It’s like to see a video dedicated to nothing but the 450 and it’s twitchy issues starting with a gas block going through to the gas key and tube The extractor spring oring or no oring issues how much pressure is acceptable to leak around the gas key it has no seal what clock position to brass should travel An actual footage of trying different buffers and springs

so which should I use, if my buffer rubber is ("just") making slight contact with the rear of the buffer tube, (according to marks on the rubber bumper) & is over gassed, with a 16" government profile barrel with a carbine gas system, to help soften the recoil, and reduce the muzzle rise, for better follow up shots, I have no idea what buffer system, or weight is uses, the buffer system is OEM. do I need to do anything with the buffer spring

Though easier to see, probably not representative to use a side charging handle because it stops the rearward travel of the bcg.

Thx. Suppose you are shooting a reduced recoil load and it occasionally short cycles ( 1 in 10 ). Would that mean taking a weight or 2 out of the buffer?

Why weight to you recommend for a 7.62x39 upper? 16in carbine length gas system for my setup.

I am converting my BCA 7.5" Pistol into a 16" Rifle. 1st, can you tell me what mil-spec buffer I currently have? Next, converting to the 16" BCA carbine gases upper, what "adjustable" mil-spec buffer would I need? Can you recommend a buffer kit? TIA.

BCA , GREAT Video. Very Informative. What Type of Buffer do you Recommend for AR10 20 "Heavy Barrel Chamber l in 308.? Please Advise...

What size buffer for a 11.5 " barrel on carbine length

Do you run the same buffer spring an weight for the 223 side charger as a standard AR over the top 223?

Any plans for a side charging 9mm or 45ACP upper?

Hi,i have a 308 Aero Persimmon with an 18'' barrel and i bought a MDT SCS Butstock to put on,not shure what spring and buffer i need to make it work,hard to get any info on it.Can i use the stock spring i pulled out of it. Thanx

My sbr is overgassed. My buffer has no numbers on it. What should I do?

My .17HMR upper came with a spring and buffer. If I change out my 556 upper for my new .17HMR upper am I supposed to change buffer and spring?

I recently purchased two upper assemblies from you, both in 2 to 3 Wylde, one is a 10 or 10 1/2 inch pistol upper and the other is a 16 inch rifle upper. would you recommend the same buffer for both? And do you have buffer assemblies available for purchase? I couldn’t find them on your site. Or could you recommend a buffer assembly from say Brownells or some other source

Okay, so the buffer weight gives the spent round time to eject, and the new round time to move into place. What is the difference between running an H1 and an H2 in a 16" AR? How much of an impact on felt recoil and cycle time does it have between 3.8 and 4.8oz?

I can tell with a heavier buffer cause I can actually feel the bolt slam back and slam forward. There is a big difference between the lightest buffer compared to a h2

So which buffer do you guys put standard in your multi caliber lower that comes with the .50 beowulf side charger?

I got your 16 inch 762x39 side charging upper. What would you reccomend? Carbine, A2, or A5 style buffer tube? Would a flatspring make any difference?

I just got a 10.5" 7.62x39 upper from you guys - seems undergassed, bolt is not going back far enough to pick up a new round. Confirmed that problem is not in the lower or in the mags. Using Wolf 122g as recommended on your website. Heavier buffer made problem significantly worse, waiting on reduced power spring to try to lighten things a bit. If that doesn't work should I start taking weights out of (standard 3 oz ) buffer or should i just send it back to you?

I believe the chart that you are asking about can be found on the Geissile website

Do you have to change the spring when going with a heavier buffer? For explanation will the spring it came with work the same with an H3 buffer or do I need a heavier duty spring?

So would my 4.3oz be an H or H2?

If the rifle length buffer was designed for 20” AR15. Does that mean the H3 would work well on a 20” rifle with carbine length buffer since they weigh the same?

Would changing out the buffer spring, to a more stiff or less stiff one, work as another way to fine tune the system?

Any one know which buffer wt is working best with 350 legend 16in barrel ?

Recently got the 10.5in 7.62x39 pistol upper. Experiencing a failure to eject post firing. Would the H3 buffer weight help?

After years of being an AK-47 man I have switched to the AR-15 I have seen the light armalight that is

I'm going to be building my first .223 wylde ar15. I got a 20" barrel with rifle length gas system and a carbine buffer system. Should I be fine with the standard carbine buffer weight or do I need to go heavier or lighter? Any help would be greatly appreciated, thanks!

Bought a bca upper 10 1/2 inch 7 62 about a month ago its having alot of failure to feeds and lite primer strikes i do understand these 762 present a prob from time to time also having lite primer strikes I want to keep it its a solid little upper is there any suggestions ? Could it be the complete lower I bought from psa do these mate well or should I buy a bca lower?

Hi I bought a 9mm upper from bca SKU 158NB-UASCH9MMCM416110M-15M3 It's 16" barrel put it on 9mm lower and standard collapsible stock I used a lower build kit from palmetto state and standard buffer and it won't eject the rounds at all I'm guessing it needs heavier buffer were should I start on wieghts

What buffer do you recommend for a 10.5 inch 556 with a wide open trigger and mil spec bcg

Does anyone have a recommendation for an adjustable gas block for BCA 223 both carbine and mid-length? Have an over-gassed situation that buffer/spring combinations are not remedying. Cycles fine but a bit harsh and ejection at 1-2 o’clock. Thx

What’s a good buffer wait for it AR15 7.5inch pistol

Waiting patiently for the return of BCA AR-10 Platforms
