| What kind of buffer do you think I should use. My upper is a 11.5 from BCM. It needs to work with wolf ammo. Thanks for the replies |

i'm using an h3 and sprinco blue spring with my 11.5 bcm bfh. also using the extractor o-ring with bcm enhanced extractor spring. it runs 100% with wolf gold in this config. was having failures to eject with h buffer and no o-ring. haven't tried steel cased yet.
eta: generally you should use the heaviest buffer that will lock your bolt back on the last round. |

I run a H3 buffer and Wolff XP spring in my PSA 10.5 inch 5.56 pistol, runs flawless and ejects at 3 o'clock. It even runs and ejects shitty steel Tulammo but won't hold bolt back on last round. I also use the 5 coil HD extractor spring with insert but without the o-ring. |
