I recently purchased a complete barreled upper, and am trying to figure out who manufactured it, can anyone help... So far it's a 7/8" round Stainless steel barrel 20" long.. The Barrel is stamped like this;

S/S
W
1/8

the freefloating handguard is ribbed not vented, and has a bi-pod lug (it's flat-top) and I am unsure where to look, and what to look for as to who manufactured the upper/BBl. Please help fellow patriots? Thanks, best wishes to all.

Sincerely,
The F.O.

Looks like it is a 20 inch stainless steel Wilson Barrel with a 1/8 twist.

I give myself a 89% chanch of being right...

Thanks for the great answers, anyone know if the Wilson Arms barrels are worth anything? So far my my favorite barrel is Kreiger cryo-forged, is this anywhere near as good? Thanks again..
