Looking for parts for my next build and Need Help Finding a Sub MOA 11.5 or 12.5 Barrel.

I've heard that Centurion's 12.5 barrel is sub moa with 77gr and is properly ported but it seems they've stopped making them?

Also on the table is Daniel Defense's 12.5 but I've not run across as many people saying those are sub moa

AR Performance in 12.5 might be available in late summer but not sure how consistently they can be sub moa with 77gr

Faxon and Ballistic advantage don't seem to be quite there.

Would be nice if it was .625 as I already have an SLR6 but this is not a deal breaker. Decent weight (no bull barrels), Sub MOA with 77gr and properly gassed.

Look at Sionics 11.5 reduced gas port barrel for proper porting haven’t run any accuracy tests on mine just yet but I have faith. Granted it wears a MRO so not sure it’ll ever be tested for accuracy.

I won’t call it proper porting because it’s gassier than a gringo at bean buffet, but it it was subMOA all day long.
https://www.larue.com/products/5-56-stealth-barrel-k/ (12” SBR w/M4 feedramps). On a good note, while gassy it did shoot every single round I fed it with and without a can. 77gr and 69gr it shot very well.

I do own a Centurion Arms 12.5, and out yesterday had 1.5 MOA @ 100 yd groups with Priv Partizan M193. I have yet to shoot 262’s, but I’ve heard that’s its sweet spot.

ETA: on the gas thing, I just did some high temp RTV in the horseshoe of my cHrgj g handle and that pretty must managed the gas well enough that I didn’t really notice it.

There’s a lot to be said for an AR isn’t a ammo snob. IMO

How is yours set up with the RGP / Reduced Gas Port? Function without suppressor?

Proof research 11.5 will meet your goal. ;).

Gotta have a beefy budget though.

Functions with and without a Surefire 762 mini, non adjustable gasblock, running a springco green in an A5 setup. Can’t remember off the top of my head which weight buffer I settled on.

Helping him find the correct area would have been nice.
