Does anyone remember Colt designing and selling a removable 9mm block system
that you can install in any 5.56mm lower? Or was it another company? |
|
is that yours? if so, how eay is that to install? I mean. is it easy to put it in a work correctly? |
|
Does that harm the receiver at all? If not I might need to pick one up for my M16A1. |
