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.

I installed on of these in my ATI Omni Maxx AR pistol. Fired about 200 rounds with zero malfunctions.
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.

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.

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.
Well worth your money. Your AR will love you for it.

Shipped fast and at the right price. Excellent quality and no tool marks anywhere. Great finish and eats everything I have fed it from steel case to brass. Bolt is true 158 Carpenter steel MPI.<br>Great price to value.
