That is an excellent idea

I've seen barrels with heavy throat/rifling erosion from sustained automatic firing...

Military rifles get more use in stateside training than they do on overseas deployments

Haven't seen combat, but the rubber molding my duty rifle's butt stock is all kinds of ripped. 😂

Last 10 years flew by.

Not even gas springs?

@@CompetitionChris gas rings?

Only 90 rounds (3 mags) on my DD V5 :)

@@NBXRacing you know what I meant lol

my dd is an overgassed piece . sloppy receiver fit. sample size of one. buzz off fanboy

I aLSO HAVE A DD M4V5. Did you order a DD firing pin from Brownells or another brand_

that's awesome Ryan, kinda makes me happy when I hear someone that has used the crap out of their weapon, that's what its made for. would love to own a DD one day, the price Increase has made it nearly impossible, but 10K rounds show you do get what you pay for 👍

eKY here and too have a nice range on my 25 acres... I have a DDm4v1 with thousands of rounds as well. I will have to go and check out my pin in the morning.

Bro I'm in cincinnati , u still got ur range?

???

Just makes bcm look better

Es muy costoso traducir los videos. No es cost effective

I second this

He mentioned what you’re asking in another video. I can’t remember which one exactly, but I think it’s the one titled why I gauge the AR so much. He modified his headspace gauge somehow so he wouldn’t have to further disassemble a customer’s rifle and possibly cause a warranty issue for the owner. He has dimensions for his modified tools he uses, but you have to take one of his classes to get the tech specs. Hope this helps.

It’s coated someway. Ferrous Metal is the only thing that will work

Ironbomb it’s the throat because a 223 is much shorter it will not fit regardless of case dimensions being same shoulder is irrelevant it never gets that far in

@@gwkgb8474 thank you for that. I've since noticed Chad's gages reflect what you just stated. The 5.56 has a longer throat that the 223Rem. A 223Wilde should accept both? There is much for me to learn yet. Best regards.🇺🇸

Yes, in Chad's classroom

@Karol D I agree. Honestly the only company I have 100 percent faith in for all of their parts is LMT.

Yep. I forgot, but I made another video.

It depends on too many variables to give a hard number. These things can have an effect on bolt life: - ammunition used - gas system length - gas port size - gas system efficiency - carrier & bolt dimensions - bolt material & finish - upper receiver trueness - throat & headspace and so on. Some bolts can go 2-3x the round count you have on yours but some don't. If you do consistent visual inspections of the bolt, and check headspace occasionally you are better off than following a round count regiment.

@@SchooloftheAmericanRifle thanks man!

I believe that in another video he used .080 and .060 line.

that is necessary when setting headspace, like replacing a barrel on a bolt rifle. Checking headspace on a floating bolt just ensures it won’t close on an oversized gauge.

@@jwilsonhandmadeknives2760 I thought that was the case, except in all these BCG gauge vids, only the Extractor is removed but not the Ejector

You should remove the ejector from the bolt when checking headspace. I believe he uses gauges that have a cutout to accomodate the ejector being left in the bolt.

My most used rifle is my 3 gun competition rifle, it has a titanium pin, after the 2020 season, I was inspecting it and it looked like the surface of the moon.

Spring insert always. Oring is not needed with springco extractor springs

Good but often over gassed. Look at sionics

the point of chrome plating is to increase reliability, so..it's really about who/how the bcg was mfg'd and assembled rather than the coating.

CB Yes. I was wondering if chrome had problems like nickel boron does where the coating interferes with the carrier keys threading becoming to thick for the screws. Or like the nitrided bcg’s being oversized in the gas runs making them less gas efficient. The types of tendencies in manufacturing problems like those must be in the chrome bcgs as well. I just don’t know what they might be.

It’s not required with springco springs. They are designed for heavy duty and have a long lifespan

I've seen Springco say that their extractor springs should have the insert or the o-ring, but not both. Putting both could cause binding. Don't know if other spring brands experience the same deal.

I was curious why the lantac is your fav?

@@_giles due to a combination of the slickness, the shape, the placement of the vent wholes to vent gas away from shooters face and if im being honest it just looks cool as hell. And we all know looking cool is half the battle 😉

@@_giles I actually made a video on some of my BCG'S you should go check it out next time you get bored

@@ShootDaily Whats your fav between the NiB and the Nitron lantac ebcg?

It’s not needed with springco extractor springs. They’re designed for heavy duty

Basically use either the insert OR the donut. Together they can create too much tension and cause ejection issues. Generally the insert is preferred. .... the donut was developed more as a “bandaid” for weak overused springs and inserts and isnt needed with a decent spring/insert

metal shavings are attracted to magnetic parts. Shavings can jam up inside certain areas of the bcg and cause problems. especially if you shoot steel case

MPI or magnetic particle inspection causes the parts to be magnetized. They must be demagnetized afterwards to prevent issues

rapid friction on ferrous material can magnetize it.

@@jwilsonhandmadeknives2760 Thanks I didn't know that, but was only thing I could imagine if it wasn't from the mfgrs magnetic inspection

Not always accurate depending on manufacturing and qc with that one round

If you shoot cheap steel case ammo or bi metal projectiles it could cause wear issues. Cycling can cause shards of metal to strip away from steel cases and cause issues

I was wondering this as well when I seen him do that. I think the aero M5 build I just did has some magnetism as I noticed the bolt wanting to attract to the walls of the receiver. Now I’m wondering if this will cause issues? I’ll never be firing steel through it if that’s the only issue. Now I’ll have to go check again to see if I’m just crazy lol

Magnetic particle inspection causes the bcg components to become magnetized. If they are not demagnetized after the inspection they will hold metal bits which is not good

They fine if used in the right application.

Lol huwhat!?

Kyler Whitcomb I was told next month.

@@richardbonner1674 Hopefully sooner than later. Brownells has had them "pre ordered" for a little while now.

Its one of the highest wear components, so after 7K the first one was probably showing some wear.

Best to change parts at first signs of wear then wait till they break. Every 2 years i replace cam pin and gas rings and o ring /extractor.

Get a solgw and never look back. Sionics is really nice and durable as well.

“Just replace the $5 part” So you want a business to spend a customer’s money without asking them? Maybe the customer doesn’t want to spend extra money, they might even have a pile of spares themselves.

It has 7K rounds on it.

Well there are some things as an AR-15 owner that you really need to understand. To start with round count is almost everything when we start talking about worn or diminished tolerances. If you take a new DD BCG and perform an inspection on it then we might be able to start drawing some conclusion as it relates to manufacturing processes or a companies ability to reinforce quality control standards. But in all reality the above example with a new DD BCG wouldn't even be a fair assessment of manufacturing quality as we would need to inspect thousands of units to really obtain an accurate conclusion. So using an example of one unit which also has 7K rounds down the pipe isn't an even remotely fair way of concluding overall quality. The second consideration is care and maintenance there is no way for us to know how well taken care of that example really was. The third thing is you need to understand that most if not all the stuff that instructor Chad inspects are wear parts on an AR-15 and they are expected to slowly loose tolerance and eventually be replaced. Also going back to care and maintenance the AR-15 is a very robust system and is capable of running thousands of rounds without being cleaned and other KZfaq channels like MAC ran a BCM 8K rounds without cleaning and almost no malfunctions but does that mean it isn't going to increase the wear pattern. If you go really long intervals without cleaning your AR-15 (e.g. 2-3K rounds) then it's going to wear quicker because all that debris in the moving parts causes wear which can accelerate the process of lost tolerances. The point I'm making is that there are several variables which must be considered when attempting to draw a conclusion about the overall quality of a product. Sometimes things as simple as ammo selection can even have a major impact on the wear pattern of a rifle. For example if a rifle sees nothing but a steady diet of steel cased ammunition it can increase the wear in several areas of the AR-15. I saw a guy who had totally lost the tip of his firing pin and he had ran about 10K rounds of Wolf Steel cased and those steel cased rounds usually have a relatively hard Berdan primer in them and by comparison to your Boxer primed brass cases the steel cased rounds wear the parts that interface with the ammunition way faster. So what I'm saying is don't draw your conclusion on this one inspection alone. And as an FYI that's why Instructor Chad always uses that disclaimer toward the end of his videos saying " Just remember this is only an example of one BCG and is not a representation of all BCG". He also places emphasis on round count very strongly when it's applicable.

"Overall, with 7,000 rounds, I'd say that this bolt carrier has done very well." -Chad, at 13:51
