Great tube


Great tube, did exactly what its is supposed to do.

Spikes tactical


Have no complaints items I purchased were shipped fast easy to navigate website will definitely visit again

Excellent quality


I built two builds with this buffer kit. It works great.

I expected better from spikes


I have bought several of these from other places and I have come to like the spikes buffer tubes, and I think they are some of the best availible. I bought these ones and the color began coming off like they were spray painted. The numbers just rubbed off. I have two others and they are still going strong years after I installed them.

Best Option in build or upgrade ideas


I replaced my buffer with the spikes st-t2 awhile back. I really liked the different in each shoot. Smoother than before! So when I started my build i piece price , and this kit saved me money. Best parts your going to fine!

best deal around and super fast shipping.


I spent about a week looking around for the best deal on a spikes tube assembly. I finally found this one and its pretty cool. Its going in a .300blk but have not yet been able to test it for proper cycling and function with live ammo. When I test it, I'll try and update the post.

better description of products


Is the tube 7075 every descriptions of aluminum should include type no such thing as aircraft aluminum.
