Aero Precision M4E1 AR-15 223 Remington/5.56 NATO Lower Receiver - Blue/Black

Very high quality machining from a great company. Perfect for a high-end AR build. Lots of videos online using this lower for a quality built AR.

This looks very trick for its price, and matches the M4E1 perfectly, super clean machining.

I love these lowers! Very easy to assemble and love the little design touches like the threaded bolt catch and integrated trigger guard. Buds shipped quickly to my FFL as they always do!

Great lower receiver, perfect fit and finish. I love Aero Precision products and have never had an out of spec receiver from them, Buds was fast on the shipping too!

Very nice lower , being threaded makes putting together very easy , already have another one on the way

This lower is strong and looks nice also. Overall it works good.

Great product. I built a 6.5 Grendel with this lower. I’ve only used the “regular” milspec stripped lowers before this one. It went together perfectly and was really nice due to the lower not having the dreaded roll pins for the trigger guard and bolt catch. I will never buy another regular lower again, this one is better in every way. I highly recommend it just for the fact it doesn’t use roll pins not to mention it’s much stronger than the standard lower. As usual BUDS was great. Fast shipping ant the lower was in perfect condition when it arrived at my FFL.
