| Looking to complete my sbr soon but nit sure on what buffer to use. Ive got a spikes tactical st-t2 buffer now but what would be better to use. |

One issue you may find with a blow back 9mm is breaking bolt catches.
Spikes came up with a plug that is inserted into the buffer tube, limiting the rearward travel of the bolt, thus lessening the energy placed upon the bolt catch at the end of a mag. The $1.75 in quarters also is very effective for this, I ran this method with a RRA buffer for some time. In the last year, I bought a HeavyBuffers.com 9mm buffer and spring. The buffer is longer and does away with the need of a spacer or quarters. Shoots very softly and reliably. Can not recommend it enough.........Slash is also a member here as well. Many threads about these here. |
| I started with a RRA 5.4oz buffer, worked fine when I was swapping multiple uppers on one lower but when I picked up another lower to make a complete rifle I upgraded to one of the Spikes ST-9X buffers (8.5 oz) and it really smoothed out the recoil quite a bit. If I had to buy one today I'd look at the Slash buffer. For a short while I tried the quarter spacer trick, it does make a difference and it only costs $1.75. I tried a Wolf xtra power spring with the ST-9X but it would occasionally shortstroke on all my 115gr factory ammo. If I were running +P or reloading hot loads I'd probably upgrade to the Slash 11oz buffer and the xtra power spring. |
