Quality Materials, Quality Craftsmanship

Every component in the Spikes Tactical’s 9mm Carbine Buffer Tube Assembly is manufactured from quality U.S. sourced materials and manufactured under the watchful eyes and skilled hands of American Craftsmen.

Spikes Mil-Spec 6-Position Buffer Tube

Spikes Buffer Tube is machined from 7075-T6 Aluminum for strength you can count on for the service life of your build. Multiple positions are marked with laser engraved numbers that won’t fade, so you can make necessary moves with confidence and return over and over again without wondering if you’ve hit the right mark.
The hard anodized coating makes the buffer tube corrosion resistant and won’t chip, crack or peel under the rigors of field use.

Spikes Carbine Length Buffer Spring

Spikes buffer springs are manufactured from electro-polished 17-7 stainless steel. They provide smooth operation and long service life that you won’t get from just any nameless buffer spring. These springs are a favorite among upgraders and builders alike, so they’re a natural choice for Spikes 9mm Carbine Length Buffer Tube Assembly.

Spikes ST-9X 9mm Heavy Buffer

Spike Tactical presented the market with this specialty 9mm extended buffer to solve problems with bolt catches breaking. In addition to mitigating those catch breakage problems, this premium stainless buffer will provide smooth performance and reduce blowback, providing you a much more comfortable shooting experience.

All American
