Best buffer kit


This is my second Spikes buffer kit, they're awesome, but this one is even better as the buffer tube no longer has that ugly gray lube coating on it anymore. My STR stock does fit slightly looser on this buffer tube than the original coated buffer tube, no big deal though.

Excellent Quality

Great Quality! I wish Primary Arms would off FREE SHIPPING with orders over a certain amount! I still cant complain when items are very fairly priced and a great selection.

Quality buffer tube assembly

by -

Another great Primary Arms purchase. The usual fast and accurate delivery experience. <br>You can't go wrong with the Spider, the milspec buffer tube assembly is top quality as per usual spike's tactical parts. The tube is coated with dry film lube and fit and finish were excellent. Fit perfectly in my stripped lower the spring, buffer, castle nut, and end plate included also were top quality. Highly recommend the assembly, its worth the couple of extra bucks. Highly recommend Primary Arms for the purchase.

Very happy
