Well, wanted to see if an airsoft/GBB rail would fit to make a clone of a knights SR15, and the short of it is, it does. Had S2 armament pop this rail on one of their mid length gas uppers (11.5 + YHM muzzle device + S2 spec Bolt, chromoly barrel) and took it home, only to decide I like the Geissele URGI better. Asking $680. No rounds have been sent through the upper. Rail is from Redwolf airsoft if anyone wants to check it out. Only trade for a zev oz9.
