Im looking to buy my barrel soon and im thinking im gonna go with the PSA 16" CHF barrel but there are several choices.
First off, what gas systems will be covered by a 12" rail? I plan on going midlength and I just want to make sure it will be ok with my 12" SAR rail. And im not sure on the differences in profiles. PSA offers a M4A1, a light weight, and a normal (??) profile. And tips as to which might be right for me? Im leaning to the light weight one as to try and keep the rifle weight lower |
