Buffer and Spring AR-47

I have a couple of PSA AR-47's. We videoed the bolt running a standard 3oz buffer. No bolt bounce reviewing it in slow-mo. I did step up to a 6.1oz buffer. It still functioned fine shooting Tula, the felt recoil stepped up with the Wolf Mil-spec still not as bad as with the 3.0

Anyone swap in an AR10 buffer spring? I picked up some Kaw Valley 9mm/.308 springs.

I usually run an H2 buffer in my 10” 7.62x39 and an H3 in my 16” carbine, which also has a Wolff xtra power spring. The carbine isn’t 100% reliable with Tula + Wolff spring but runs Wolf Premium, Brown Bear, Golden Tiger & surplus M67 all the time.

Thanks for the reply.

Perhaps there is some published spring ratings somewhere.........
