20" SPR Barrel Sizes

[dbshelton]

Anyone know the 20" SPR Barrel diameters and dimensions?

[carnaby]

I do!

They are 0.84" under the hand guads, 0.75" at the gas block, and 0.72" to the muzzle. I already offer these in an intermediate gas length setup that can be drilled to work as a rifle length gas system. I will be offering dedicated rifle length gas system 20" barrels with fluting under the hand guards in the next batch. Probabaly a month or so off.

Can I order a 20" barreled upper with a target crown instead of threaded end? If so, approx how long wait?

[carnaby]

Yes, I have a few of these coming in. I should have them in 2 to 4 weeks. Do you want rifle length gas system with fluting under the hand guards, or intermediate length gas with no fluting?

No fluting. Which gas system length is preferred?

[carnaby]

I prefer the intermediate length gas system. No fluting on these.
