Cannot wait to put rounds through it. Alresdy recommending Spikes to several friends. As always, awesome customer service and convenience from P.A.

As always, nice fit and finish to compliment my Spike's lower. This is my second ST upper receiver and am very pleased. Fast shipping and excellent customer service.

Spikes forged M4 Upper


Beautifully finished to match a spikes lower. Great service as usual from Primary.

less than I expected


Bought the upper expecting it to match my Spike's Honey Badger lower but it didn't. The anodizing was a lot lighter than my spikes lower receiver (nice dark black)and it should have been a Blemished upper because of the shotty anodizing and the scratches it arrived with. Also was pretty loose when I mated it with the Spike's lower receiver. Primary Arms shipped fast and they get an A+ but the spikes upper gets a C-.
