Hello,
I've never fired an ar-15 (legal obstructions on this side of the puddle) but I have a great interest in all kinds of firearm designs.
Does the ar-15 have any way of venting off excess gas?
I have a rifle quite similar to the m1a or m14 type rifles. When the gas piston has moved some distance, a hole in the gas chamber is opened, which vents off excess gas. This is not enough moderation to make it function reliably with any kind of ammo (as you might know, you're not supposed to feed your m1a with bullets heavier than 180 gr), but at least it's something. Many gas operated mechanisms have some kind of provision for venting off excess gas, but since the ar-15 has no moving parts near the gas port, I figure there's no way to do this.
Of course, there are plenty of remedies availible to handle over-gassed ar-15.
What about other DI systems? The Ljungman and the MAS 49/56, do they have any vents for excess gas?
Just curious, that's all .
