Description
The Precision Defense™ 5.56 M16 Complete Bolt Carrier Group is machined from high-quality materials to ensure your AR-15 will run reliably as long as you have ammo to shoot it with.

This is probably the lowest price I've ever seen for a BCG. I don't know anything about this brand or their quality, but I do know that you can get a Toolcraft nitride 5.56 BCG at Arm or Ally right now for $68.99 plus $7.99 shipping = $76.98 total with shipping and no sales tax. This brand from Primary Arms would have been $71.34 with shipping and sales tax. I would rather pay an extra $5 for a known quality product that has a no questions asked warranty! In fact, that's exactly what I did earlier today. This is the 5th Toolcraft BCG that I have purchased and all but one was perfect. The one that wasn't perfect was purely just cosmetic. The nitride finish on it was more of a dark brown than the usual deep black. However, I took advantage of the no questions asked warranty by giving them a call and explaining my dissatisfaction with the blemish. They politely and quickly emailed me a return label and within a couple weeks from the time I mailed it off had a beautiful deep black nitride Toolcraft BCG. They even included some Toolcraft stickers in the box. Another time, I was reassembling a bolt and launched the ejector across my shop. As hard as I looked, it was never to be seen again. I gave Toolcraft a call and explained what happened. I had a new ejector and some more stickers in the mail within a few days and they wouldn't even let me pay for it. For those reasons, I will always purchase Toolcraft over anything else as long as their prices stay competitive.
Is this a re-branded Tool Craft BCG???????
I have both. Doesn't seem to be. Tooling marks abound (uncommon for Toolcraft), though the finish is still pretty smooth. Both bolt and carrier are 9310 instead of 158 for the bolt. Still seems to be made acceptably well for intended budget builds or spares.
Read the reviews on PA. Seems like heavy tooling marks and one of the commenters said it wouldn't cycle in his AR15. Sounds like junk.
