Gorilla Machining AR-15 M4A4 Anchor Harvey Tan Magpul FDE Stripped Upper Receiver

Excellent fit and finish.

Finish is as close to magpul fde as can be. I’m using a TN arms lower that’s polymer filled to match magpul exactly and this upper is dead on. Nice finish and good quality. Just what I needed for an all fde honey badger inspired pistol. I’ve also purchased other uppers From this company with good results. Very good company for affordable/quality builds.

I'm building four upper receivers, two in .223 Wylde and two in .300 AAC. I'll eventually need to buy two more upper receivers to finish my project. I have another one, that has a different foundry mark and has T-marks along the top. The one from Gorilla Machining isn't quite that fancy, but is fine. Also, the barrel socket is not quite as tight as the other upper receiver. For that one, I had to heat the receiver to expand the metal so that I could install the barrel. This one is snug, but not an interference fit. Good, or bad? To me, it doesn't matter that much. Everything else about the upper receiver is perfect. Good finish, no blemishes that I could see.

These upper are high quality , cheap and US made no wonder its always sold out . Gorilla machining makes high quality products .

Very nice finish on this fde stripped upper.
