When I needed parts to build quality lowers, I went directly to BCM. BCM delivers quality components at good prices.
I used these parts on a carbine build. Fit and finish are great. Mounted to my lower with no issues, good tight tolerances.
This far I can only comment on the install and it fit my lower reciever as expected. I'm slowly putting my AR 15 together and piece by piece. I'm hoping BCM gets some more stripped upper recievers instock after the holidays. I pick BCM based on their web reviews ands what my friends recommended.
Well machined, no imperfections and lock plate channel is square
Good quality. Fast shipping. The MFT minimalist stock fit great on it; clean finish on the tube.
Quality product made in USA. Great fast shipping and well packaged. Thank You
