Great ReceiverReview by
Quality

There's really nothing to say other than this is an amazing receiver. The fit with the billet upper (bought separately) is extremely tight and the tolerances seem right on. While it's personal preference, I just wish they made it with bullet pictograms instead of text and an ambi mag release to be a true ambi receiver. (Posted on 3/13/2017)

This lower includes a plastic tipped tensioning screw, threaded bolt release pin, and the hardware for the right side bolt release. The right side bolt release works well with good leverage and placement of the button, it cannot be used to lock the bolt open. The finish is excellent, a nice deep black anodizing that has proven to be tough. The machining and dimensions are excellent, it matches well with standard forged uppers, but really looks and fits great with Mega's own octagonal uppers and monolithic rail assemblies.

This lower has subtle changes compared to a mil-spec forged, it is slightly thicker and slightly heavier, but does not have the wild lines and angles of some other brands that tend to look cool, but get in the way of handling. The magwell is slightly enlarged to speed mag changes. It will take a standard LPK, all pins fit properly, I used mostly improved parts as this build is primarily for 3 gun, an AR gold and Giessele trigger fit perfectly, as does a BAD selector. The only slight fitting I had to do was slightly shave the beavertail portion on a Magpul MIAD grip where it meets the thicker grip pocket area of the receiver between the grip and buffer tube. All in all this is an excellent lower with a practical design that included subtle custom features along with excellent fit and finish for any build. I have built on several other billet and forged lowers, and this is probably my favorite, especially combined with the MML and billet uppers.

Perfect for high-end buildReview by

Fantastic lower, fit and finish are flawless, make sure to get the ambi model, way more elegant that a Magpul bad lever. Also, I love the small screw in pin used to hold the bolt catch assembly, far better design than using a punch-in roll pin. (Posted on 3/16/2016)

The best you can buy. Be sure to match it with the billet upper which is what it is designed for. Tight fit great looks! I love it. (Posted on 8/15/2015)
