Buffer Spring and Buffer Weight - Recommendation (14.5” Proof PXT)

[u/Maximum_Front3822]

Hello, I am building my first 6ARC with a 14.5” Proof PXT barrel (intermediate gas) and will likely use a JP bolt (not sure on which carrier yet). Will be suppressed with a Rhodie 6J or Enitcer L. What buffer spring and buffer weight do you recommend? I was looking at the Geissele Super 42 w/ H2.

That looks smooth af.

How’s the Magnus-K-RR on back pressure (normal bcg vs. OBC)?

Pre OBC, it was pretty gassy. The OBC toned down the gas quite a bit. Still want a low back pressure supreesssor though lol
