Folks who complain about reliability in semi-autos offten do so because the gun has not be kept clean and in proper order, the reminton or benelli is a fine gun, I used to own a Benelli M1, was a while ago and it was one of the HK imported ones, it worked, but yes kicked like heck and I have seen them have problems from failing to cycle after too many modifications and tacitcal stuff added or if not held really tight as both of these things affect the inerta recoil mechanism, the remington should be much more resistant if not immue to these problems.
Not to mention that the beloved and costly M4 that the maries and everyone else use is not an inerta recoil system gun, though osmeone may jump on me with more technical details, it's a gas operated gun more like the remington than a M1 so the reminton system and ideas can't be quite so outdated to someoen at benelli or the department of defense.
