Spikes mil-spec buffer tube


Perfect fit and finish



Primary Arms is fantastic. I had accidentally entered the wrong shipping address and didn't notice until the next morning, just before the order was shipped. Laura in their customer service was very quick to get it corrected. Thank you very much. The Spikes buffer tube assembly arrived very fast and in perfect condition. I haven't been able to test it yet as I'm slowly building the rifle it's attached to but I imagine it will work flawlessly when that day comes.
