This 80 lower is fantastic! No flaws and fine finish even in raw form. I highly recommend these guys/gals. top notice quality.

I have been buying from M1 for some time now. I only ran into one issue on an AR10 lower. I was able to fix it and when I called M1 they gave me a discount on my next order. I'd say I've used 30+ receivers from M1 and only one issue. If they are backordered it is worth the wait.
