I have 2 BCA, a .50 and 16" 5.56. Both shoot with no issues. The GF is dialed in, my .50 shoots really low at 25, I was just trying to get it kinda dialed in then move it out to 50 yards, just moving to 50 with some cardboard around the target and see how it does.

I am looking at buying a wylde from them soon.

 

I've used their barrels and receivers in a number of builds without any problems, BUT I will note that all my purchases were prior to them being raided by ICE and like 67 of their employees hauled away. I've watched on Facebook as folks had terrible problems with their current calibers OTHER than .223 Wylde and 5.56.

 

Built in America....by Illegal Aliens huh?

 

A while back I bought a complete side charge upper in 7.62x39. It started having problems so I contacted them. Good enough customer service. I can't knock them for effort. Quality control was a bit off though.

I suggest you go over anything assembled and make sure it's all tight.

Zant, my side charge handle kept coming loose until I gave it a drop of blue loctite. Now I keep an Allen wrench in the soft case for if I need to remove bolt

 

Like I said-it was a 50$ barrel-if it was 2-500$,there would have been major complaints.Cleaned up the ramps with a Dremel,they look better and seem to function.
The sidecharger was my fault so I'll try and get the broken shaft out this week.Luckily I had a few uppers laying around.

 

I use 3 BCA and 1 Faxon barrels in 7,62x39. None have given me feed issues with Pro Mag's 20 rounders.
