When you run a CMMG .22LR conversion in your 5.56 AR-15, the smaller cartridge and different bolt setup leave your forward assist doing nothing. That's where the CMMG 22ARC Forward Assist Adapter Kit comes in. It's a small piece that fits into the upper so the forward assist can actually push against the bolt again, giving you a way to seat a round that doesn't want to go all the way home.
Rimfire ammo tends to be dirtier and less consistent than centerfire, so every now and then a round hangs up before the bolt fully closes. With this adapter installed, a quick tap on the forward assist can finish the job and get you back to shooting. It's molded from durable glass-filled nylon, which holds up to repeated use without adding weight, and it's designed to pair with CMMG's Alpha and Bravo conversion kits.
Installation is about as simple as it gets. The piece drops into place inside the upper and works alongside your existing bolt carrier group from the conversion. Keep in mind it sits under light tension, so it stays put while the BCG is in but can lift out when you pull the bolt for cleaning. Folks who run these kits regularly consider it one of those small parts that just makes the whole plinking setup feel complete, closer to how a factory rifle behaves.
If you already own a CMMG rimfire conversion, this is the kind of add-on that fills in the last missing piece. It's inexpensive, made in the USA, and backed by CMMG's lifetime guarantee against defects in materials and workmanship. For anyone who wants their .22LR-converted AR to feel and function like the real thing during a long range day, it earns its spot.
It fills the space inside your AR-15 upper so the forward assist can once again push against the bolt when running a CMMG .22LR conversion kit. Without it, the forward assist has nothing to grab because the rimfire setup uses a different bolt. With it, you can tap a stubborn round into battery just like on a standard rifle.
It's built to work with CMMG's Alpha and Bravo .22LR conversion kits dropped into a 5.56/.223 AR-15. If you're running one of CMMG's dedicated rimfire setups, this adapter is the matching piece that restores forward assist function.
Not at all. It drops into the upper receiver and works alongside your conversion's bolt carrier group. Just be aware it's held in by light pressure, so it can lift out when you remove the BCG for cleaning, then set right back in place.
It's not strictly required, but rimfire ammo is dirty and occasionally a round won't seat fully. Having a working forward assist gives you a simple way to close the bolt on those stubborn rounds instead of clearing the chamber, which is why a lot of owners add it to complete the setup.
