Ratings & Reviews
Just received this stripped upper. Got to say the finish is very well done. No machining marks. Have not assembled yet but its looking promising. Definitely would buy again

This receiver is machined well and went together without issue. I have had a couple uppers during Covid times machined out of alignment or spec (I'm looking at you WMD), this Expo is NOT one of them. It is good to go out of the box. Even the face of the barrel threading was square and didn't require lapping. The price makes this a great value.

Arived fast looks great
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.

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.

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.
