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.
