Gorilla Machining M4A4 Anchor Harvey Stripped Upper Receiver

I received an upper with the Spike's Tactical spider on the top near the charging handle, upper was a great product, very solid and seemed to fit well with my build!

I love the price . If they keep these spider uppers for 60.this will be only place I buy my upper.they was few imperfections with anodizing but that don't bother me I build mine for use. Not for looks. So if you have to critique everything look on. Came with upper parts to install.im very happy with mine thanks gorilla ! Excellent price just hope to see same uppers at great price.p.s. waiting on some other parts to come in stock will b a returning customer.

This is a very nice upper receiver it paired well with my 80% lower that I received from gorilla machine. I look forward to doing business with them more in the future.

I now have 2 of these. Can't beat the price for an assembled upper.

Fit and finish were great, no issues with the build or using it.
