I have ordered a RRA 9mm flattop upper with CAR handguards. Can I replace with the 3.75" OLY FIRSH......I dont know how the barrel is made????thanks in advance.....

The FIRSH installation requires that the front sight tower be removed, so a permanent muzzle device may be an issue. Also the barrel will have to come off to replace the barrel nut, for the FIRSH to mount to.
