Spike's Tactical 6 Position Mil-Spec Buffer Tube


Primary Arms was out of stock on this one. I received an email from them a day later saying it was back in stock, and I ordered it right then. I received the Buffer tube very quickly. Talk about easy to install. I used a Magpul CTR Stock. Primary Arms has the best Prices and the best stuff. Shipping is reasonably priced too.

Buffer Tube and Buffer


Purchased this setup to replace the current tube/buffer on my Windham Weaponry Vex and to accommodate my Fab Defense GL Shock Stock. Super snug fit and no wriggle.

Quality product...

Worth the $


Really great quality, no spring jingle, Spikes buffers really soften operation... good stuff!

Installed easily


Received about a week after ordered, all parts included, went on internet to watch a You-Tube video of installation, and did it in about 5 minutes. No problem. The firing testing begins when my Magpul furniture arrives.....

Spikes buffer tube


Shipping was super fast solid buffer tube great buffer

Good Product


Spikes has great products. Not much you can say about a buffer tube. Primary Arms is great to deal with and they have a great selection of black gun parts.

Spikes Tactical Buffer Tube Assembly


Spikes Tactictical products have never let me down. The Mil-Spec Buffer Tube Assembly that I recently purchased from Primary Arms is no exception. Because of the quality of Spikes Tactical products, they are generally the only parts I will use for my builds. The service from Primary Arms is always top notch. Best online store around. And... if you ever need to speak to a real person, Primary Arms' customer service is top notch as well.



Standard quality



still testing the t2 and seeing how it runs with my PSA bcg. The logo definitely catches anyone's eye when I take it apart
