Has anyone tried an 18 inch 6.5 CM barrel with Rifle+2 gas? The reason I ask is I have a 22 inch with +2 gas that I only run suppressed and an 18 inch would be handier. I'm not concerned over velocity loss, just function.
 
I have a Craddock Precision 6.5C 18" Rifle +1" barrel and it runs like a sewing machine unsuppressed. I think you'll be in the clear with +2" suppressed.

Curious did you chop your 22" barrel down to 18" and if so how is the 18" running with the +2 gas system (suppressed and unsuppressed)? Contemplating a 20" Proof SS barrel which only comes with the +2, which I would probably chop to 18"! the 4-6month wait for CP or CLE is just killing my build!

No, currently it's still 22 inches.

CLE is only running 10-12 weeks at the moment I believe.
 
I'm running a CLE 18" 6.5CM Bartlein in a LaRue OBR right now with fantastic results, I would have gone +1 but the OBR handguard is only 13" so the gas block would stick out like dogs balls. The only change I had to make over the rest of my 6.5CM with the + Gas systems is I had to step up and run a H3 Buffer system.
 
I ordered a carbon 18” rifle length +2” from carbon six, it’ll be a couple more months before it’s complete, but I like that you can get it built to your specs. I did a 7 twist and a .936” Ti adjustable gas block. I currently have a 20” proof that shoots extremely well so I’m excited to see how the 18” works. Like others, I am looking forward to something shorter.

Give us an update when you test it out, do you know the how big of a gas port it is?

I ended up picking up a 18" Rainier UM with rifle length gas in 6.5cm for my build. But if this barrel sucks I may go the proof SS route and chop her down!

I think the gas port is .100” and regulated by the adjustable gas block. I’ve had really good luck with carbon 6 barrels on bolt guns, so I am looking forward to seeing how their gas gun barrels work.

Well I know the proof port size for 20" & 22" both with the +2 gas system is .086 so I'll be curious to hear how your rifle runs with that port size and how much restriction you need suppressed/unsuppressed!
