Excellent BCG
The Stag Arms nickel-boron BCG I receiced was well constructed and totally devoid of any tool marks. The gas key was well staked and all the other components looked great as well. The outer surface was very smooth and moved effortlessly inside of my upper receiver. I haven't finished my AR build yet, but I did test the action with some dummy rounds and BCG fed and ejected them very well.

Nickle Boron BCG
I purchased the Nickel Boron Bolt-Carrier Group as an upgrade to my standard OEM BCG. I couldn't be happier with the craftsmanship and quality of this product. I love STAG!

Nickle Boron Bolt
Bought one a while back, slick as owl sh-t on a greasy corn cob, works like it should. I believe it can't be beat.
Thanks Stag keep up the great work. -
Probably one of the best mid-range BCG's you can get. Mine came with my Stag 6 upper and has had about 5000-6000 rounds through it and has yet to show any signs of wear or damage (including the Bolt, gas key, firing pin, etc.

Nickel/ Boron BCG
Stag had a one day only sale, on this BCG, and it was half price at $84.00 . I have their base Model 1 AR-15 I bought from them in 2014, so why not (at this price) treat myself to an upgrade. Fits like it should, runs like it should and is much easier to clean than a standard BCG. Well worth the FULL price. Very pleased. My rifle, with this upgrade, is everything I need and Stag has my back the entire way.

Beautiful bolt assembly!
This assembly is beautiful! It functions flawlessly and is easy to clean. No malfunctions at all and fits my new Stag upper perfectly. Extremely smooth action that puts all the shell casings into a nice pile on the ground. I'll have to get more of these during the next sale.
