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!)
There have been product for shotguns on the market that go into that deep screw counterbore. I’m nor sure which ones are still on the market. I don’t know that any of them were any more effective than just adding weight to the gun.
If you managed to bubba an AR buffer in there, it probably wouldn’t do anything but make the gun heavier. The AR buffer is acted on directly by the AR bolt carrier…no carrier, the buffer probably moves very little if at all under the recoil impulse alone. And if it did move, I would be worried about it eventually cracking the stock.
There’s likely purpose-built products you could try.
Also, changing the buffer weight can impact the reliability of your AR. Don’t just put a couple mags through and call it good. Ammo, fouling, even ambient temperature can trip things up. It’s common for competition shooters to fiddle with that stuff to get the maximum shoot-ability they can, but there’s a reason the mil-spec buffer is the weight it is.
Ah! With no BCG to hit it, it won’t really move. Knew I was missing something.
So far, so good on the H3. I’ve got about 200 rounds of crappy ammo through it, and it’s filthy. As to temps, I’ve gone 90F to 50F. Haven’t been in the cold with it this year.
