Out of stock

This buffer is one of the softest shooting, smoothest and quietest buffers on the market not to mention it looks awesome. It doesn't have any weights to move around or fluids to leak out, it's 100% maintenance free!

It weighs in at 4.3oz. (Depending on the density and size of the HDTP, the weight can vary slightly.)

It's CNC machined from Solid Billet Aluminum Bar Stock.

It's Anodized Matte Black and Laser engraved with Spike's Logo.

So you're probably wondering what's inside to make this thing so great and different

Each buffer is filled with HDTP "High Density Tungsten Powder" so there is No reciprocating weights inside to make a lot of noise. It also makes for a Very Smooth cycling rifle. It eliminates the chance of bolt bounce and muzzle rise in full-auto. It also cuts down on Felt Recoil. It's a HUGE upgrade from a Standard Carbine buffer! It's designed for .223/5.56 but it works in all Calibers!

After it's filled with HDTP it's topped off with a mil spec bumper!

    I am currently running one of these in a mid length 14.5 AR and a carbine length 10.5 AR pistol. they both run smoothly.
    I would choose spikes buffers every time. They run quieter and smoother then standerd buffers due to the tungsten powder inside.
    I highly recomend these to anyone looking to build or upgrade there AR.

    Works great as advertised. Installed on a Spikes Tactical 5.56 Lower enhanced paired with a Troy Upper. Very happy. A little pricey though

    I really like this buffer. I loved it in my Spikes Tactical carbine so much that I purchased this one for a PSA mid-length build. Very smooth & quiet....& I'll buy more if any other AR-build projects develop.

    Received my buffer with very fast service. The quality and service was all that I expected from a great outfit such as BCM. I have used their products in the past and plan on doing business with them in the future.
