Just swap this drop in conversion with the bolt carrier group from your 5.56/.223 chambered rifle and you will be ready to shoot .22LR. Ships with one or three 10 round magazines. All Stainless Steel Construction. The magazines are polymer. Works in most 5.56/.223 chambered rifle.

Great experience buying from MSR Arms! Price beat everyone else by a long shot.

besides saving money on ammunition, this is the quickest way to make your AR “California Compliant”: Does it Use Centerfire Ammunition No. It is NOT an “Assault Weapon”.

This product is a work of pure genius. So simple to install and works flawlessly. MSR Arms definitely has the lowest price around. The money I saved purchasing from them allowed me to get the 3/25rnd mag package and upgrade to 2 day shipping. The only draw back would be the magazines. They are 25 rounders, but I can only fit 20-21 rnds in them. Not a big deal as I’m only using this product for target practice and small game. CMMG hit a home run with this conversion kit.

Shot without issue but not as accurate as a regular 22.

Preformed flawlessly, ran 300 rounds of bulk Remington ammo through it the first day I got it. No issues. It does get very dirty but that’s a function of 22lr ammo and not a flaw in the product, just be prepared for some cleaning after you use it.

I use the cheapest, crappiest, dirtiest 22 ammo available and this thing cycles them flawlessly!!!!! They say you pay for this thing in 1000 rounds. I’m pretty sure I’ve already paid for it with all the shooting I’ve been doing in the last month! This thing works wonderfully and allows me to have fun with my AR without breaking the bank!

Since the great state of California has stopped online ammo. 22lr is going to be a great way still go shooting with out breaking the bank.

This conversion worked flawlessly. Standard velocity works fine. Point of aim nearly identical to center fire ammo at 50 yards.

Works well with all different kinds of ammo no miss feeds and only one or two misfires. (Probably the ammo) it will make your upper very dirty but that’s expected with .22. 25 rnd mags are also made well and do what they are designed to do.

I ordered the CMMG 22LR AR Conversion Kit on a Thursday and MSR Arms had it at my home on Saturday. The kit did not fit into my chamber so I called CMMG and they said it was made for the 556 and may not fit into tight 223 chambers but it is made of brass so it can be filed down to fit. When I told them I did not want to do any DIY machining on rifle chamber parts they shipped me a new chamber adapter in Stainless Steel, free of charge, which arrived within a few days and worked perfectly. I have shot the rifle in it’s 22LR conversion with zero issues. I highly recommend MSR Arms and CMMG based on this order and I would not hesitate to order from either company again.

It’s a great kit. I have fed it some of the cheapest ammo out there and it performed beautifully. It’s great also because you don’t have to get another rifle to have a 22LR and buy another optic for it. Saved me money. Also, the conversion takes less than 15 seconds. I recommend it to anyone wanting to teach their kids how to safely use the AR platform because the recoil is the same as a pellet gun and the noise is minimal.

Using in a Core15 and it works great.
Greg R. (store manager) –
Yes. Buy it. Love it. No regrets!

Very nice peace of conversion, simple easy to install, easy to switch from 5.56 to 22LR bolt carrier, no recoil but you look like shooting with BB gun with brass flying on your side

I put the conversion bolt into a PSA 16″ upper on an Anderson lower with the Palmetto lower build kit inhanced trigger model, swapped trigger springs for JP inhanced trigger springs and WOW WOW WOW…. this 22lr conversion bcg can go on all day long. Only had it a few hours and in 200 rounds not one flaw or fail to feed, fire, eject, chamber next round and repeat. My new favorite accessory for the BYO AR-15!

Runs great with decient ammo, fits great in all our AR’s. Mags fit nice and tight for us as well, no wiggle front to back. Ammo choice is key, Remmingturd caused ftf but CCI ran like a champ! Accuracy is best with CCI as well, very few flyers, nice groups, right in the spot @ 2550 yrds with minimal adjustments to elevation….thats pretty cool! I just hold over instead of adjust my sights, super easy with mildots. Best bit of kit an AR owner can have! Get one, you will like it, its fun! We shot with the kit until we ran out of ammo it was that much fun.

This conversion is So much fun and so simple to install, not to mention pretty accurate.. Like most all guns/barrels you’ve just got to find the ammo it like’s.. well from super cheap to some super match grade this shot great out of a ballistic advantage 16″ .223 Wylde BA Hanson Stainless Steel.. Good luck and buy lot’s of ammo.. =)

The best of engineering.
Works flawlessly even with Remington golden junk.
My only wish is a bolt hold open redesign that will work like The Better Mag Adapter without having to switch mags to S&W 15-22 type.
Bottom line if you want to shoot at your indoor range or take a pest in the back yard with little to no noise and not spend a fortune on .556/.223 ammo then this is for you.
30 second change over to and from .22 lr to .556/.223 it’s like having two guns on one.
What’s not to love about this conversion kit !
Oh and I received my kit in 3 days Fast Shipping
Thanks MSRarms
