Product Description
It is made from Solid CNC machined 6061 Billet w/ Black Anodized finish. For the serious shooter on a tight budget. This spacer is for the guy who already owns a 9mm buffer like the one offered by RRA or Colt and doesn't want to replace it with another $60-$90 custom buffer. The ST-9BS is designed to limit the travel of your 9mm bolt. The 9mm cartridge isn't near the length of a 223/5.56 cartridge so it doesn't need the same amount travel. You are just wasting energy and creating more wear and tear on your expensive 9mm AR15. It helps eliminate the chance of breaking bolt catches. With the spacer installed your bolt doesn't have a running head start to slam into the back of your bolt catch and break it off or damage your lower receiver. It also makes for a much smoother shooting gun. The less distance the bolt has to travel means you are going to have quicker follow up shots. The ST-9BS also increases spring pressure, which means a little less gas in your face and more out of the muzzle. To Install the ST-9BS spacer you Simply remove your buffer and spring. Install the ST-9BS on the end of your spring like you would with a buffer. Drop the complete unit "ST-9BS, Buffer Spring, and Buffer" into the buffer tube and start shooting again. The ST-9BS is ONLY compatible with 9mm! The ST-9BS will go Perfect with the ST-T2 tungsten buffers we offer but is NOT compatible with the ST-9X or ANY other extended 9mm buffers on the Market.

Cures an actual problem.
Absolutely took care of bolt over-travel in a 9mm AR, ending the bolt hold open breakage. I combined it with a heavy buffer which also served to slow the bolt travel. Well worth the few bucks.

Works as advertised
After installing it I went to the range. There was less recoil, less gas discharged back at me and the action cycled faster.

Smoother cycling while slide firing
This spacer did smooth out the cycling of my 9mm AR especially while slide firing. I have snapped two bolt catches already and did not realized I needed a buffer spacer to prevent that. I have shot with the spacer now for about 600 rounds and seems to hold up well and performs just as advertised.
