SOTA makes good stuff - and stands behind it with excellent customer service.
My friends have two of their uppers in 5.56 with stainless barrels.
They have been very reliable and hold 1" at 100 yards until you really heat up the barrel.
I had one of their very first batch of 7.62x39 stainless uppers and it is a good shooter easily holding 1" with Wolf HPs.
The bolt spit a couple of lugs after a few hundred rounds.
I contacted JoAnne at SOTA and she asked me to send in the bolt or take pictures.
I took good pictures and sent them in.
She said they had a batch of bolts in 7.62x39 that missed heat treatment and the one I had was one of them.
To my surprise, I had a new bolt, cam pin, firing pin and pin retainer in my hands in 3 days!!!!
And this was back during the crazy times a few months ago.
The upper gets shot a lot with nasty ammo and still runs like a sewing machine.
I am hesitant to purchase an AR upper in 7.62x39 but would buy another one from SOTA!
