Blitzkrieg Components PCC Buffer Weight 2.6 oz


Blitzkrieg Components / KynSHOT PCC Buffer Weight/Spacer 2.6 oz

Our PCC buffer weight can be used with either of our PCC hydraulic buffers to add mass in front of the buffer. It adds .75" in length to the buffer system, adds 2.6 ounces in weight and is designed for a close fit in buffer tube to prevent 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 buffer tube and keeps impact straight on buffer for best effect and longest service life, and it's additional length can be used to make a short stroke system if desired.

The PCC buffer weight is inserted into the buffer tube after you insert the buffer and spring, so the weight is in front in the buffer tube. During cycling, the weight is in between the bolt and the buffer. It is sized for a close fit in the buffer tube for minimal tilting and smooth operation. We have found that fit is very good on POF and VLTOR buffer tubes. Some brands run a bit smaller inside and may be too tight. So if in doubt, check the measurements.

If you want to use this weight and have your bolt cycle the full distance and get behind the bolt catch, then you will 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.

This weight can be used with either the standard RB5007 buffer or the RB5015HD buffer. The weight is made of machined 17-4 Stainless Steel.
