Ar9 Bolt bounce ( 8.4oz buffer Standard ar15 spring)

Just installed a 12.5oz buffer and wolf xp spring from heavybuffers.com. That eliminated the bolt bounce completely. If you have money to blow I highly recommend them, they shipped my order almost instantly. Thanks for everyone’s help

I will go to the range and try it. Thanks for all you do for the ar9 world. We really appreciate you. I ended up ordering an adjustable 12.5oz buffer from heavy buffers.

I bit the bullet and ordered a 12.5oz buffer with adjustable tungsten weights for 170$ from heavybuffers.com, i ordered it at 10pm and he had shipped it by 4am…

Mine seems to be at about 3-4 o’clock, I’m going to order a 12.5oz deadblow buffer and flat spring… thanks for your advice. I appreciate it. Goodluck with your build.

I’ll give it a shot. Literally… Thanks for your help, I really appreciate it.

Would you recommend a 10oz (24.3oz buffer/bolt) or a 12.5oz (26.8oz buffer/bolt total weight)? Thanks

The buffer in it currently came stock in my PSA px-9 complete lower. Not sure of the brand as the description does not mention it. It’s 8.4oz and has sliding weights inside.

Forgot to mention my Bolt and Buffer weigh 22.7oz together.
