Well worth it!

The only thing that could make this better is T-Marks...IF you NEED them. Great machining, beautiful dark anodizing...flawless. Will by again.

I bought this for a MK18 300 blackout clone build along with an Expo Arms/Mega Arms lower receiver. I couldn’t be happier with the upper receiver and combo. I’ve run about 500 rounds through it so far. The machining seems and feels top notch. The figment with the small parts and the lower receiver is nice and tight. Very pleased and I would definitely recommend!
Very nice

Good to Go!

I used this receiver in conjunction with the Expo Arms 11.5 inch SOCOM barrel and no issues with fitment of barrel, upper receiver parts, or handguard. Great deal on a well made receiver and I will most likely be using another one of these for a future build.

Incredible Value

Received my upper today. Everything is in spec and it has a beautiful deep black anodizing similar to Zev/Mega or GGP. Of note the front of the upper above the gas tube entry is marked M4. The upper is also marked with a square from the forger. I don't think you can beat the value on these uppers.

Got my upper today and finished out my build. The upper has a nice, jet black anodizing very similar to zev/mega/GGP. Everything was within spec. Of note, above the gas tube entry on the front of the receiver it's marked ME. Not sure who the OEM for these is but that indicates it's likely a military contractor. Mine had a square forge mark as well. I don't think these can be beat for the price.
