Hello Everyone, I just purchased an upper from Copper in the EE. Great guy to deal with but I have a question or two for all of you about the upper. 1. The upper has M4 feed ramps. Do I need a special bolt/carrier for this upper or will any bolt/carrier work? 2. The muzzle break appears to be pinned on (total of 4 pins). I don't see any sodder (sp) on the brake or the barrel. If I unscrew the pins will the brake slip right off? Thanks, Accountant Here is a link for a picture: Colt Upper |
