I know the AR buffer is a totally different system than what I’m proposing. But still, I have an old spring and weight I could try with just a little widening on the shotgun hole.

Also, I realize the hole isn’t angled to kick straight back. But might I see any reduction in felt recoil?

(For those not in the know, as I wasn’t last year, you can easily change the weight in the AR system. LOL, didn’t know you can pop the spring with a car key! I went up to an H3 (heaviest) and it still cycles like a dream, even with crappy .223. Wasn’t sure how much difference I was feeling until a friend and I compared with his stock Aero. Holy shit did his kick harder!)
