Product Description
Spike's Tactical stainless steel heavy buffer for use in a carbine stock. The ST-9X Weighs 8.5oz. The ST-9X is a dedicated 9mm buffer due to its extended length. Its extended length helps eliminate the problem of breaking bolt catches. The buffer is CNC machined from top quality 304 stainless steel to a beautiful finish. It has a mil-spec bumper on it retained with a stainless steel roll pin. It is also laser engraved with our signature spider logo and model number. The buffer will smooth the gun out, make it more reliable and decrease the amount of gas in your face when shooting suppressed.

Spikes st9 x buffer
Works good, nice and smooth

as expected but....
First shipped parts purchase on my first AR build so don’t have much to compare it to. Product looks as advertised didn’t give it 5 stars yet until build is done and tested. The buffer arrived scratched, scuffed. I assume this is due to storage, lackof wrapping and poor packaging for shipment. Nothing that should affect performance but still disappointing receiving in this condition when paying full list price.

9mm Buffer.
Installing the Spikes 9mm buffer made the rifle so much smoother than with the standard buffer that came with the gun. The one that was installed at the factory seems to be an H2 buffer weight. Rifle is smooth and very quiet. More enjoyable to shoot.

Spikes 9mm heavy buffer
Excellent product, I was running a heavy carbine buffer, worked ok. Replaced with this buffer and the recoil practically disappeared. Function is flawless. Fit and finish is perfect, exactly what you would expect.

Good heavy buffer
Works well with my New Frontier Armory modular bolt, 8.5 inch barrel, unsupressed, and standard carbine spring. So far has had no trouble cycling anything I have put through it, including 147gr subsonics.

it works great
I've use this in conjunction with the mill spec carbine spring CMMG ramped bolt Mil-Spec receivers and Hahn dedicated block.

best option
I went with several other brands of heavy and extended buffers for my pistol caliber carbine. Most had the weight but wasn't long enough. The Spikes one has both. Will be getting another one soon.

works great
Works as advertised to reduce the bolt travel under recoil. Use this with an XP buffer spring to reduce dot movement. A must have item with a 9mm AR build. Works much better than a regular 9mm buffer.

Used this with a wolf heavy spring and worked out perfect. Spikes great product as always.
