65 or 6mm CM gasser setup

[Big Moose]

Considering a build, and just wanted to check to see what other people are doing in terms of gas tube length, gas block, bolt carrier, bolt, and buffer spring?

I've heard these are quite difficult to tune. From the research I've done it seems the trend is towards a rifle +2 inch gas tube with a lighter bolt carrier.

My 24" 6.5 with +2 gas is butter smooth and very easy on the brass.

I did not have a lot of luck with a 6mm 22" +2 gas. Issues with pressure and feeding. The long skinny 6mm didn't feed very well so I was limit to lower BC bullets.

Thanks for your response. I've heard most people stick with 105s or 108s.

22” +2 has system in 6.5CM.

My research showed the +2 has a better dwell time and made the system work better. Not saying a non +2 doesn’t work, just the intel I got back from users and mfg.

I have a 22" +2 gas system 6 cm with a heavy buffer and heavy spring. It feeds good but still working on a load that shoots tight groups. Been shooting 107 smks.
