What non printed parts do I need to complete this build I know I need a cmmg 22 lr conversion BCG and protobarrol but is the max upper required for this build ??
You must log in or # to comment.
You just need the bolt and barrel like you said, plus an ar fcg and all the misc hardware. A mac upper is not required for the 22, only if you want to swap to 9mm. Also for 22 printed side plates will work, but if you ever go 9mm you will need metal or cf plates
I had a question how is the rear trunnion sitting on the lower because I can’t get my holes to line up just right
It has 2 screws that go in the rear of the trunnion, then the side plates as well.
