The garbage

by ThatGunGuy, Verified Owner from AR, United States Written on March 9, 2025
This product was cheap enough to try. Got it in and the bcg was in 2 pieces. The bolt itself wasn't in the carrier, found out the rings were hitting the inside of the carrier and bending. I replaced the rings, went in fine. Got it together, put in rifle, started shooting. The extractor was not letting loose of the spent casing. Jamming every shot. Had to pull handle back and hold it while releasing the mag and using my finger to push the casing out. Took bolt apart again, and the extractor does not budge at all with our alot of pressure and using a tool.completelt out of spec...

Great fit and finish, just what I needed to complete my build at a good price. I’ve put 500 rounds through it so far with zero issues. I will purchase again for my next build.

out of spec

by Brian Reynolds, Verified Owner from CA, United States Written on June 20, 2024
Completely useless BCG. It was so far out of spec that it wouldn't even seat into the upper receiver. It would bind and get stuck before seating into position and was even difficult to remove. Thats what I get for trying an unfamiliar brand on sale. Yes I did try another bcg to make sure it wasn't my receiver that was out of spec. This has already been shipped back as a return and I will pay a few dollars more for one of my regular trusted brands.
