I took my wife and son shooting last weekend and noticed, again, that my Colt SP-1 makes a distinct sproinging sound. I assume this is from the action spring reverberating inside the buttstock. With every shot you can hear (and feel) a "sproingssgggggggggggggg" for about half a second. The rifle is 100% stock AFAIK. I've never shot another AR but I did shoot an M4 (full auto) and I don't remember it doing that. But I may have been deafened by adrenaline.
Maybe it's the "old style" action spring? I assume they've probably been upgraded or improved over the years... or do all ARs go sproing? Everyone who shoots my rifle comments on it.
