Yankee Hill Machine AR-15 Billet Upper Receiver - Stripped

A slightly unique design which looks sharp. Some slight issues with the finish but YHNM and Primary stepped up, and solved the the problem with zero headaches.

I really like the look of this upper. Very solid construction And tight for on my stag lower. One thing to mention is some over sized bolt releases won't fit. Not a deal breaker for me, but be warned. Primary arms is by far the best customer service I have ever had

Nice construction. Product quality is superior. My only concern is that the release is recessed.

Purchased this to mate with billet lower. Nice clean lines. Whole build stands out from the rest of your typical AR's. The design just flows.

Seems of solid construction and I like that the cutouts save on weight. Be aware that there is a cutout for the bolt release that will not fit the Seekins bolt release, and probably only the standard bolt release. Found this out the hard way. Also like any billet upper, it won't fit into a standard Wheeler upper vice clamp block, my preferred method for securing the barrel nut. I just wrapped the upper in cloth, put it in the Wheeler upper vice clamp block, and it did the trick. Although I felt I should have bought the DPMS upper receiver action block that holds the upper from within, I didn't want to spend another $45 bucks on it. It worked out in the end, but it felt a bit sketch.

The price was great on the YHM billet stripped upper, worked out great. Only complaint I have is the first stripped upper I received was a basic key mod forged upper, called and got talked with customer service and got it straightened out.

This receiver has lines that go well with the yhm 125 billet lower and yhm 5155 handguard (both carried by PA if I'm not mistaken). Must have if you want a yhm model 57 type rifle. You can trust primary arms will ship swiftly. I will do business with them again soon.

Yhm always top notch.
