Just Fantantastic!!!Review by
This upper replaced an Aero Precision C.O.P. on a 10.3" SBR which was great, but not perfect (weight being the main issue)!!! The Mega Arms MML-320 is just a beautiful and excellent upper, not cheap, but the price is 100% worth every penny. In my eyes is just a perfect MK-18 type SBR Fit and finish are excellent, assembly is easy and included instructions are easy to follow, there is not one bad thing I can say about this upper. This was my first M-Lok upper or rail and still not 100% sure on M-Lok, but Key Mod is also available. The entire system dropped about 1/2lb of the total weight compared to the C.O.P. My next build will be in a .308 MA Ten configuration. (Posted on 11/24/2016)
This is my third Mega and they just keep getting betterReview by
I have several other AR-15 Mega uppers including one AR-10 MATEN and this one is REALLY nice. The fit and finish is beautiful and I work in an Aerospace machine shop so I know what quality machining is supposed to look like.

I bought a Mid length for a Mid length build but didn't realize that the forearm will NOT cover the gas block. The Mid length is only 9" so if you want to cover the gas block on a mid length get a rifle length upper. That was not exactly clear in the description but I guess I should have asked.

It even comes boxed in a foam cut out case including the nut and wrench and of course all the screws. The Upper also includes the forward assist and the dust cover so its ready for you to bolt in a barrel. Even the pictorial instructions were very nice. IF you want a quality product get this.
