how can i install a FIRSH rail on my postban AR15 without taking it to a gunsmith?
thanks in advance
It requires FSB removal for barrel nut swap. If your postban has a permanently attached brake, that has to come off before the FSB can come off as well.
After the FSB is off, installation is a piece of cake.
so in lieu of taking of the FSB, i can what rebarrel? or buy a new non sunset upper?
how about the two piece quad rail forearm by Yankee Hill Machine?
is it any count?
