This kit is the whole reason I was able to get into AR-15s, I’m a not so rich parent of 3 and if it wasn’t for this kit I’d never have been able to shoot or practice with my AR-15s, thank you CMMG 🙏

I love that you guys finally have a video about this out. I'm constantly being asked what the differences are between the various generations and now I can just send them this link.

I have probably put 20k rounds through my old bravo kit and have never once had a shell end up in a standard ar15 charging handle.

I love my CMMG .22LR stainless steel conversion kit. Mine even works with the original notched hammer in my 1986 AR-15.

I've used your kits for quite some time and I find them to be an invaluable training tool. Thanks for making great conversion kits! My first AR15 was a CMMG M4 style WASP that I got as a kit about 15 years ago. I miss that gun (it lives with a family member now and is still running great, btw).

Had a Ciener from decades ago. Bought some Blackdog mags and it ran well. Bought a CMMG and it is still working well. Then I picked up a dedicated CMMG upper. It’s nice to have an actual .22 barrel.

These kits are awesome. I had an older one which I shot out and your customer service was at better than I could have asked.

Brilliant design, everyone can play as long as they want, I love mine.

The 'Original' kit was made by Jonathan Arthur Ciener and referred to as the JAC. Later a man named Rick Kuhel (sp?) made dedicated barrels for the JAC conversion with a feed ramp adapter that replaced the chamber adapter. This meant you had a dedicated .22 upper, but it was ridiculously reliable and you weren't spitting bare lead down your good .223/5.56 barrel. The JAC kits were hard to get ahold of because of lower production numbers and the Kuhel barrels were even fewer so. CMMG was the fist to provide units to supply the market, but first runs had some issues and could be finicky. Now they are making units the standard for AR .22 conversions.

I have a dedicated CMMG 22LR upper that has functioned flawlessly for years, I love it! It is far more accurate than a drop in conversion becasue of the 1:16 twist. I compete with it out to 200 yards.

I bought one of these off of a friend yesterday, he said that he didn't like the point of impact shift. 🙄 But I've been running the hell out of it today and I love it! The only gripe I have is this thing is the king of light strikes. It could be because of my LaRue trigger, but I don't know. I removed the firing pin spring, and the thing runs like a sewing machine. I might get a stronger hammer spring so I can reinstall the firing pin spring, because I assume it's there for a reason. I was surprised at how well it runs subs, once I found that out, I wanted to marry the damn thing. 😂 I just can't get over how much fun running subsonic .22s I an AR is! The money savings is pretty damn nice, too.

Just bought your kit recently. So far, so good.

This was a must with my 57 Dissent....great video

Ìve been using this kit in my seekins precision. 223 wild for yrs and never had an issue other then out running the bolt! These are awsome!

I bought mine based on all of the good reviews. My experience has been terrible. Feed issues, casings getting stuck. Tried Winchester, CCI and Aguila. Also added the bore buddy and upgrade kit. In frustration I emailed CMMG customer service and never got a response. Bought a 10/22 and it runs flawlessly.

I recently bought the Echo kit and two extra mags and it runs like the scalded dog Johnny B says they do. I also own a pre-Banshee MkG 45 and the new Dissent Mk47. I’m proud to be a CMMG fanboy. I like both their products and their people.

I got one of the Evolution magazine I wish yall start back making them I like the look and they worked fine for me

Thank you for the video!!!!! Funny you mentioned wylde.... my wylde ars are the only ones that have major issues

I got the 22lr bolt and 4.5" barrel combo and i love it. Able to build my own custom banshee, but i use M&P 22 magazines.

I have three conversion kits, these all work great with the old-style mags and the 22lr charging handle. Before replacing the new style, mags and adding the 22lr charging handle I could not go 10 rounds without one problem or another, it seems like the feed angle is different on those new mags.

Love the conversion !

Got the stainless with the extra weight added. Not sure, if it's even needed. Works like a treat and saves soo much money.

I just bought a 3 mag kit a month ago from Brownell's...... haven't try it out yet.... This is the best item to have if you have an AR....

Bought one last month. First mag was a nightmare. Probably 10 problems. Tried a higher velocity ammo and oiled it again…same issue. 3rd mag was CCI mini-mags and it worked better still several problems. Went back to the first ammo, brown box Federal bulk and it shot flawless. Then it started eating ammo like crazy. Burned through maybe 150 more rounds and other than the occasional spit of gas it is working great.

Started with a cmmg upper and couldn't get it to run on a standard lower with three different triggers. Got the borebuddy reliability kit and their black dog mags and it ran great. Bought my next three barrels and bcg from borebuddy and have had zero issues past crummy ammo.

I’ve almost got one of these kits several times. Going to have to eventually haha. Great video

Great video. I have the early kit. I always wondered if the current magazine would work with it.

Or….you can take a McDonald’s straw and stick that in the CH 🤷‍♂️ But I would totally advise you buy the CMMG CH. I have 7 of these kits and I just added a YHM extension on the CMMG CH and it runs amazing

I didn't know there was a probability of a jam using the standard charging handle. That hasn't happened to me in thousands of 22. But it's good to know. I love this adapter. It works perfectly fine with the ammo I have in a small 4" 1:7 5.56 upper works perfectly. The ammo I have doesn't shoot very accurate out of my 16" 1:9 dissipator upper.

Tips from years of using this during 0 degree celius and lower(less energy in the bullet due to temp and low quality ammo tends to be on the cheap side with energy): Wash the inside of the magazines, or buy new ones. 22lr carbon and 22lr gunk that is applied to the bullets (sticky stuff) gets inside and causes failure to feed. Polish the steel, yes you heard me, pull the BCG and the plate apeart, and polish it good, as in the contact surfaces.(the plate and the bcg touching area, NOT the slide area touching the inside of the upper) Do not use oil on it after. Polish did more for reliability than anything else. Use fine paste, as in polish paste, as you are just supposed to make the surface smoorth and reduce resistance, not remove metal! Even the new cmmg charging handle gets things stuck. Check the upper gas port and see if you can fill in more mass to close it off in the cmmg custom charing handle. Or make a custom upper, and reove the gas pipe and stake the hole in the barrel. Or get a actual 22lr barrel that has a 1:16 or something, made for 22lr. Even with all of the above...it still fails, but less. Major problem with 22, is not the solution here, it is terrible amunition. Most failures are FTE and FTF, and this is a complex problem created by a multitude of causes. not just one thing. The above can helps to alleviate some of it.

Love these kits

The very best upgrade that can be made to these kits is the crescent shaped firing pin from Bore Buddy, which provides much more surface area for striking the rim of rimfire ammo. I have spent way too much money on a 4.5" Solo Blaster variant with all of the Bore Buddy goodies and a binary trigger. The thing runs flawlessly and catches plenty of attention at the range.

I installed a kit on my AR and really liked it. However, I decided I didn't want to shoot dirty 22LR in that gun. So, I bought a CMMG 22LR barrel and built a dedicated 22LR AR. I had to modify the adapter BCG to use with 22LR barrel. Easily done . That rifle shoots great! Thanks CMMG!

I run one of these in an MCX and needed to buy an overpriced aftermarket part to be able to use my charging handle. I would love it if you guys sold an adapter for the MCX like you do for the dissent

Nice to be able to train with your actual bedside gun rather than a different 22

Polished it up… runs great with the binary. Only thing that sucks is gotta zero the sights every time you switch back. Idk maybe I’m missing something

Make the forward assist adapter weighted and adjustable. Like the Bore Buddy system.

Best $120 I've spent. Saved me probably $2k in ammunition costs. Have to say to not expect stellar accuracy out of the barrel insert, but the dedicated barrels work fine. Get better groups out of a 9 in cmmg barrel than a 20 in 223 wylde.

You didn't mention whether they will work with full auto lower. Or Registered search??

Do the new mags lock the bolt back on the bolt catch somehow instead of the follower? That would be cool

Just got 22barrel with colar, I'm going to see if phosphate unit will work with it. I didn't realize they had 22 specific charging handle.

I assembled my own dedicated 22lr upper a few years ago, I used the 9" barrel. Besides occasional bad 22lr round it runs great & is stupid fun! I've seen upgraded fireing pins & extractors made from a harder metal. But I haven't had any issues so I haven't tried them. Have you? Is your 22lr bcg still completly factory?

I made a PVC pipe holder that stores either the Bravo or the regular BCG depending on which one is not installed in the rifle. Just a short length of PVC pipe with two friction fit caps. I wrap the BCG in a piece of paper towel and slide it in the tube. I lost the rubber boot, other wise I'd keep it on the conversion kit. What size rubber hose (gas line) do I need for a snug fit? Lastly: Put a quarter between the BCG and the buffer spring will reduce the rattle when the conversion kit is installed. It acts like a shim and puts just enough pressure against the BCG. Just push it into the buffer tube as you close the upper.

What's the timeline on the different versions? I have a brass collar on mine that I got around 2018 or 19. Works fine in both of my 223 wylde rifles. I also keep the protective sleeve for when I store it

It works fine in 223 wilde. I've done it a bunch of times. 👍👍

I had my old kit with a brass colar split on the brass colar. Cmmg was awesome with warranty, and shipped a replacement quickly with no fuss. The magazines have lasted through thousands and thousands of rounds suppressed and not even cleaned. Fantastic product, fantastic company. Everyone should own this kit.

Can you make one for a gas piston gun? Like the brn 180 416 Jakl or something?

i bought the complete upper, ( BCG, upper handguard flash hider, dust cover, 22lr charge handle with 3 mags) but i see you dont offer it as a package anymore i want the ambi handle but im too poor to spend it on a dedicated 22lr setup

I had one of the ones with the collar until the chamber adapter ruptured. It ran great. You guys sent me your newer one piece chamber adapter, and this one does not feed reliably. Do you have any suggestions on how to fix this?

Now you need a magazine loader assistant..

Can confirm the bravo kit works fine in 223 wylde barrels. There's noticeably more fouling in the bore but otherwise there is no impact to the shooting experience.

I have two units and dozens of magaines! I have the forward assist adaptor, but it's not needed at all.

I've got one of the older kits with the brass collar that I've been using for close to ten years. I use it in conjunction with a Boonie Packer Better Mag Adaptor, so that I can run the conversion kit with S&W 15/22 mags. It has been awesome!

Who were other makers of the .22 conversion kits? I have one of the older units and from what I remember there were no markings on it. Somewhere it is buried with some old parts and tools that are buried in the garage.

Are they full mass now? Do I still need a sear trip kit? Does it still take the same CMMG 22lr mags?

You missed the best setup. Using the 22lr conversion kit with the anti bounce adapter in full auto!😀

I keep having failure to feed and atove pipe issues. Using 36 grain Winchester white box 22lr. Occasionally have a fail to eject too, not sure what is going on with it

What’s the best ammo to use in it. I bought one and the complete bore buddy kit

Would be nice to see them being sold with some of those aftermarket bolt weights, they're kinda necessary.

I bought two of those kits a few years ago with the three black mags. One kit for me, one for my oldest son. Do you have the part number for the better charging handle to use? Thanks...

I've never (knock on wood) had a case go up in the charging handle

Do all of the 22 BGC's work with all the various mag generations? In other words, can I get a new BGC with an old mag and run it?

@CMMG quickly questioned I got a AR 22LR can I just get a 556 upper or I need a lower as well ??

I love mine. It's great for those that don't plink. Have had many first timers love it too. Fingers start feeling like a Pin Cushon after a while though. *Please Make A Speedloader!*

Borebuddy took it a step further 😊

Does this kit work on piston driven ARs?

Does the adapter for the dissent work with other side charging uppers? Or just the dissent?

Piston upper compatible version next?

I do need a birthday gift.

The grey/green mags were fine if you only loaded 20-22 rounds. I keep the rubber boot with all my conversion bolts, it keeps the chamber extension? From getting damaged when not in use. I love them. Got me and mine thru the thin times during the plandemic when ammo was scarce or way too high priced. Great value.

2 years ago I bought the Banshee chambered in 10mm, can I convert that to the 22lr?

OK.. so .. What about Mkg 9mm to 22lr? ?

Why did yall stop making the 10mm in the dissent or did yall make it a nd stop or what hell happened

22 lr needs 1:16 twist,1;8 dont work well. Do a bolt and barrel change! Bear Creek!!

I’ve been interested in one but I’ve seen people have reliability issues with them which makes me hesitant.

Now make one with a heavier bolt, rubber bumper, dead blow buffer weights and other upgrades all built in.

Unfortunately I have a PWS in 223 wylde

Ones have been made for the AK platform before with disappointing results…but I bet CMMG could make a reliable Ak .22 conversion kit.

...seems your kits were originally made by Ceiner???

The only thing I dislike about the kit would be loading the magazines

Mine jams constantly

being that I'm a loser poor. I still cannot afford the CMMG .22lr conversion kit. and I absolutely want/need one, so bad that I would give my left _______ for one, and @52 I do "not" want anymore kids anyways. However I want the CMMG .22lr conversion.

How about not constantly shaking the object you're trying to show, set it on a table and do a close-up.

I KEEP the rubber boot on when not in use! Edit: all my kits run Flawlessly, i give them as stocking stuffs for Christmas, well before Bidenomics i did.

How well does the 22 works since the barrel has a larger diameter. The rifling/twist rate will not effect the the 22, how does this affect accuracy over a traditional 22 rifle?

But they still need aftermarket bore buddy reliability parts kits to run right, unfortunately.

Stop, shaking, the, things.

The 10 round magazines kills my interest in this product unfortunately.

odd that your product is cheaper on 3rd party site than your own.

6:45 Compliance is consent

Yeah new mags suck!!! There junk

Mine constantly jams no matter what ammo I use… waist of money!

Or you could include everything in the box from the get go and stop making people have to buy parts afterwards…
