Quick warning, there have been some makers, not big name of course, that have cut flutes too deep. I think all can see the problems this can create.

Roger that ! I've wondered if fluting can be cut too deep, but you've given me the answer. This is a Wilson barrel, 16" fluted stainless without threading for NRA competition. I purchased this barrel from a dealer here that stipped it out of a Wilson Combat rifle. I'll be throwing it in an LMT upper with a titanium bolt and bolt carrier.
I've purchased a Noveske stainless 16" without fluting for one of my other builds. It's a 1:7 twist with the Match Mod O chamber for the Mk262 77 grain. The final build is LMT lower and upper with National Match two stage trigger and the LMT SOPMOD stock, LaRue mounts, M68, SPR E, and the magnifier mount. I used a low profile gas block and the LaRue 11" SIR system with the propietary locking system. BUIS are a Troy Ind front flip up with an A.R.M.S 40L rear sight. It co-witneses the Aimpoint and the Eotech exactly on par with the reticle. I went with the KX3 hider, but then purchased the Phantom hider after deciding that the KX3 was a bit overkill and I wanted to mount a suppressor on this build also. I'm not mounting any white light as I'm not an operator and do not need to light up the outdoor range during the day. (sarcasm) I also took TR's advice and used the PRI Gasbuster charging handle.
Since I've had a bum right eye I haven't had the opportunity to fire this build as of yet. it's warm, in the 70's here this weekend and I was hoping to get out but this eye required yet another injection yesterday. I'll give a range report on the latest build when I do.
