I have a couple of A1 uppers that I want to build as 5.56 SBR uppers.  I am wanting a light weight stainless barrel pencil profile with .625 gas block journal. prefer 11.5 or 14.5 length.  Basically looking to do A1 upper, A1 FSB, and old skinny carbine handguards, with a stainless barrel.

Is it unlikely I'll find such an animal even if I go with a .750 FSB?  No Fluting, no funky cuts & profiles , just a basic pencil cut without any crazy laser cut company branding all over it. Barrel twist 1/7, 1/8, or 1/12 would be fine.

Or give me alternative ideas for utilizing my A1 uppers for my SBR. I've also contemplated a 9mm upper. I would consider a thicker profile, but still stainless, and still with an A1/A2  FSB.

Not interested in anything other than stainless for this particular upper.

Can the stainless steel be nitrided?  Or are you wanting a sliver colored barrel?

Polished or bead blasted stainless without any further coating or finishing beyond that.

White Oak did a special run a few years back, 14.5" pencil barrels.   I bought a couple, but they're gone now.  

I'll keep an eye out

16" pencil barrel in polished SS.  Know nothing about the company.  Could be cut and crowned to 14.5 before fitting the fsb

Rainier also does a LW 14.5, but they aren't in stock at the moment
