Fantastic BCG

by -

Put together my first AR 10 in 6.5 mm Creedmoor. The Nickel Boron BCG feels and looks substantial. It worked flawlessly and I am very happy with my purchase. I would definitely recommend this product.

Fails To Extract

by -

Cartridge is sticking in bolt and fails to extract. While checking BCG I noted that I can place spent cartridge into bolt head and it will hole cartridge in place even while shacking BCG. No other BCG I have will do this. Tried numerous other spent cartridges with same result.

We are happy to help you get this resolved per our conversation. Please keep an eye out for our email on this.

Could’ve Been a 5 Star Review

by -

At 1st sight and install this bcg was great. Then I went to shoot the brand new rifle I had just put together, and the bolt would not charge into full battery with a live round. The bolt extractor was literally ramming through the rim of the brass casing and jamming to the point of not going into full battery, therefore not firing. Did some research online to find some forums talking about parts manufacturers were sometimes adding a 2nd o-ring on the extractor spring making the extractor really stiff. Checked mine out and sure enough it had two o-rings. Removed one o-ring and that fixed my issue. Bcg functions as it should now with a small amount of scarring across the casing rim but that should wear in as more rounds are put through it. So just be sure to check for the o-rings if having my same problem.
