great barrel for the money
bought this barrel on sale and threw it into a lightweight build, headspaced just fine with a cryptic coatings bcg and forster gauges, cheap effective barrel that was putting moa groupings with match ammo and a rest in windy conditions, no real need for a finer quality barrel unless you want to get scientifically accurate with all the rest of your parts or lock your rifle in a vise for shooting and really get serious, this barrel does it all for much less and to nearly the same degree as barrels costing 3x

crappy head space
looks great fast shipping, but didn’t pass my match guages, cobratac took the barrel back no problem.

I am VERY impressed.
I got a .308 barrel. Its a fantastic lightweight barrel. I did check headspace and it did not meet march grade headspace. But Cobratac made me realize that, this is supposed to be more of a 7.62 NATO chamber. So it wont headspace with match grade gauges. It will pass a with NATO gauges, or a 308 field gauge. But after a conversation Cobratac i realized this is not a bolt action chamber I'm used to checking. It is held to a little longer of a headspace so we can all shoot all that steel and surplus ammo out there. Once I got a book out, read all of the mins, maxes of the .308 I realized that all of our gauges are actually under the maximum headspace by quite a few thou. (Which is what you want for .308 match grade bolt action barrels)...
