First purchase


After completing my first purchase with Primary Arms, I can say that the shipping time and the quality of the item I purchased was perfect. No issues at all. I received updates on the status of my purchase, and all went well.

A Quality Lower - Excellent


The fit and finish is outstanding. We've used a couple of these in recent builds with great results.

I like spikes for consistent quality.This lower fit &n finish is perfect.

Solid lower for a first build


High quality lower receiver, well machined with a good finish. Assembled with Spikes LPK and buffer tube. Zero issues. PrimaryArms delivers on ease of order and superior customer service.

Quality product, and the best price anywhere.

When I look for a quality lower receiver, I believe that Spikes Tactical is one of the best. I was looking to put together a 9mm rifle, I knew I would get the best lower receiver at the best price. Primary Arms has become the first place I look to when I need any AR Parts. Semper Fidelis.
