You'd be surprised how much difference the buffer tube makes in the felt recoil of your AR-15 carbine. Whether you're putting together a custom carbine or just want to upgrade your pre-built model, the Spike's Tactical Carbine Buffer Tube Assembly Kit is the best way to go.

This kit is based around their durable 7075-T6 aluminum AR-15 buffer tube. The tube features six holes so that you can get your adjustable stock exactly where you want it. Built to Mil-Spec standards, the tube comes with dry film lube for corrosion resistance. The ST-T2 buffer is weighted with tungsten powder to absorb the recoil effectively and quietly. The spring is made of 17-7 stainless steel and is designed to resist binding that occurs with lower quality springs.
