KYNTEC | KynSHOT Spacer Weight RB1501509

The KynSHOT buffer weight can be used with the PCC hydraulic buffers, and in certain cases, with the AR hydraulic buffers to add mass in front of the buffer. The Spacer Weight also adds .75" in length to the buffer system, and adds 2.5 ounces of weight, which is designed for a close fit buffer tube while preventing tilting of the buffer during cycling. The weight has several functions: the additional mass further delays initial bolt movement and slows the bolt velocity, it helps to keep the buffer aligned in the buffer tube, and its additional length can be used to make a short stroke system if desired.

 Benefits
If you want to use this weight and have your bolt cycle the full distance and stop behind the bolt catch, then you need to use an AR-10/A5 length buffer tube since they are .75" longer on the inside. If you use this weight with our buffer in a typical AR-15 buffer tube it will create a short stroke system that stops forward of the bolt catch. Additional mass is very important in any PCC short stroke set up since the bolt doesn't have as much time to slow down.

Specifications
Optimal set up - Kvnshot believes that the optimal set up for most 8-16" barreled guns is to run this PCC Buffer weight in front of an RB5015HD buffer with a .308 carbine buffer spring in an AR10/A5 buffer tube for full bolt stroke. If your bolt has a weight pinned into the rear of it, Kynshot recommends leaving that in place to retain full mass of your bolt. There are customers who like the short-stroke set up the best and everyone's perception is a bit unique, but it has been Kynshot's experience that the full-stroke set up is the smoothest running and softest recoiling overall and you retain the use of your bolt catch.
