I have looked at acouple of different units but the CMMG unit seems to be the easiest to come by. The mag prices is also good to. However, I want to know if they work and if they dont will CMMG actually fix it? I dont mean what the thing says above. I only ask because of an issue I had with the p90 1/2x28 adapter I purchased from them only to learn later it was not suppressor compatable. When I called on the phone and mentioned it showed with a suppressor on their add on the fiveseven forum they only offered to sell me another. Since then I have steared away from CMMG for an upper, a gas piston system, and now wondering about a conversion if I should go spike and spend a little more.
My setup is a 10inch piston AR not select fire. I am interested in using 22 conversion for mostly within 25 yards. Thanks.
