Breech Plug O Ring

[cnelk]

I was hanging out with a buddy the other day and we were discussing blow back around the breech plug.

He said to put a small O ring in the primer pocket to seal it.
I did some research and found a place to get specific O rings for this.

Anyone ever try it or have first hand experience?

I buy them thru McMaster-Carr. They don't last too long but they are cheap. They do stop the blowback.

but not all primers need the o ring.

depends on model and type breech plug.i believe Sabotloader is the go to on all things o rings and shims,and vent liners. i would check with him. i have a few olde CVA-S thanks to the breech plug vent mods and rubber o rings i can shoot BH 209 cleanly now.
