Gorilla Machining AR-15 M4A4 Stripped Upper Receiver Blemished

build many M16 and AR and can not tell the differnece between this upper and a mil spec no blemishes seen either and now have three of them.

I dont mind the blem. Functions fine. Happy customer

Everything is absolutely up to spec on this upper. no parts fitting or adjustments required. And it shoots just as well as my friend's gun with the high-end parts and big-name upper on it.

This is a decent upper ,highly functional.I paired it with a Anderson lower and it has a little loose play but not too excessive.It's fine for an entry level build,installed accu wedge to tighten up the fit so all is good.overall I built two and both have the same fit,slightly loose play.I would buy again,for the price you can't beat it.

We all have a nick or chip this is a great upper. Will buy more. Great part.
