Did not know that. Thanks for pointing that out. I seem to remember this as a design feature of other weapons, but I am not an expert.

- hga 14y agoIt's all part of AR-10/15 design, which has one very big issue, gas is injected directly into the receiver (not where you want cruft), but also some big virtues: fewer moving parts and potentially lighter in weight overall, inherently the most accurate semi-auto design (much less is moving before the bullet exits the barrel, and it's all behind the barrel, not parallel with it), and the front is lightweight since the center of gravity is moved backwards compared to piston designs. I'm told AR-15 pattern rifles rule in 3 gun competitions (pistol, shotgun, and rifle/carbine) because of the weight distribution, which of course also is a virtue in close quarters combat/battle (CQB). I can't remember this feature in any other designs, but there are very possibly some ones that I'm not interested in and haven't learned the details of. Almost every other design puts a piston forward, which naturally incorporates the recoil spring. There's also the roller locking recoil designs, the ones that I'm familiar with (G3/HK 91, StG 57) have their piston forward as well, although that's not strictly required by the mechanism.
