I recently ordered a RRA CAR A4 with Wilson 16" SS barrel and factory weaver rail gas block. Can you tell me how high the top of the rail is above the barrel? I'm looking at bushmaster's BMAS front flip sight for gas blocks and am trying to find out if it will work with my new RRA CAR A4? I know YHM makes this sight for BM but need to know if they are the same height? I like the BM version better!!!TIA!!!!
Nothing yet. My head armorer is supposed to get it ona rifle when he goes out to the range this week...from measurements, I THINK it will work, but I would still rather he confirm it with real range testing. Steve/RRA
