"Trigger Slap" on an 7.5" AR - Question

[Bulldog]

Hi All,

I've got a 7.5" AR and it suffers from what I'd call trigger slap. (Forceful trigger reset, enough to hurt my finger)
Being and AR Noob and knowing that the shorter the barrel the more crisp things can be. I figure it's over-gassed but I'm looking for your thoughts on possible improvements. Ejection is running at about 3o'clock. Runs great other than the trigger. Gun is bone stock, 100 rounds through.

I'm thinking either a heavier buffer or buffer spring would do it. I've got already got a 9mm buffer (not in the gun) and can order an H2 buffer or heavier spring.

Thoughts? Thanks!
Craig

What brand rifle?

My bet is it's the trigger unit is wonky, gas pressure and buffer weight should have nothing to do with trigger reset unless it's one of those special units to allow super fast firing. I would recommend trying the rifle with a known working lower to confirm where the issue is.

I doubt gas has anything to do with it. Sounds like a trigger issue.
