CMMG 22 Bolt – Forward Assist Adapter review

very thorough post. ty

Awesome video, really thank you for saving my wallet. I have sleek side upper for my 22lr but sometimes it doesn’t feed all the way so I wanted to get a new upper with forward assist with the Cmmg FA kit. Now I know this doesn’t work so I am not gonna waste money on buying a new upper

I agree with you’re discovery got the cmmg bolt also I found golden Remington also do that problem. Only brand I found works is CCI mini mag rounds it’s due to the smooth copper head bullet if it has a grove or ribbed it will cause that failure to feed or other feeding issues

Also, you don't just push the FA with your thumb, you hit it hard with your palm!

I have the same problem

Well keep in mind a lot of manufacturers do not offer a forward assist for a reason…. it's dangerous. The rim crushes to ignite the primer… think about that for a second. You run the risk of out of battery KB which probably wouldn't hurt anything on the gun but definitely can hurt you or a bystander. I believe CMMG makes it a polymer assembly so you probably damage the forward assist before you can actually crush the rim.
Edit: Actually CMMG states the forward assist is made of glass filled nylon similar to the guide/bolt stop on their magazines. You say it's a design flaw, but I believe this is intentional for safety reason.

Good to know about the FA. I don't think I'll get the adapter then. Save some cash. Thanks.

I have a forward assist adapter from fostec outdoors mad of steel and it will close the cmmg bolt all the way it is part of a kit to convert the cmmg bolt to work with the echo trigger, the adapter is supposed to help prevent bolt /hammer bounce.

Great video. Can you show the .22 conversion bolt for AK ?

Really no reason to have one in your situation. How often do I ever need a FA on a 22 kit you might ask? Never have seen the need to have one in the thousands of rounds of 22 I have shot thru my AR.
