This is the BCG that I use in all my uppers (.223, 5.56 and .300BLK). The finish is very smooth and cleans up easily. With a "lifetime warranty" from Toolcraft and fast shipping from PA, you just can't go wrong.

BCG looks like a work of art.
<br>Arrived dirty tho, full of polishing media or something.
<br>Most importantly, bolt is marked C158, not 9310.
<br>I count that as a positive, I guess.
C-158 bolt, billed as 9310?

BCG arrived in a a bubble wrap envelope inside a Uline box...nothing from Toolcraft as far as boxing or documentation.
<br>Ok, I guess...I'm easy going...
<br>But the carrier was full of some kind of stuff, I'm guessing polishing media?
<br>Dis-assembled and cleaned..bolt is a thing of beauty, but stamped C158, description says 9310...wtf?
<br>My first PA buy.
<br>Shipped fast...wondering if I should gripe and return.
<br>From PA: We've been getting mixed batches of C158 and 9310 on this one. We'd be happy to accept a return or swap it out for you.

I installed on of these in my ATI Omni Maxx AR pistol. Fired about 200 rounds with zero malfunctions.
A really nice BCG at a GREAT price!

This item is of good quality, fit & finish comparable to higher end competitor's BCG. I'll be purchasing more real soon.
