One of the biggest questions I am asked about when I built my PCC for IPSC was what type of buffer system I went with. After spending countless hours researching buffer systems for 9mm blowback rifles in the last 2 years this is what I found. I hope my experience and research is able to help those that are lost on what buffer systems to use.
Here are the most common systems used from least to most expensive,
They all work, but which one will work best for you?
All do basically the same thing, they all control the smoothness of the buffer movement and delay the action a slight bit for less recoil and better reliability while at the same time giving more stability and a faster follow up shot.
After hours of research, I decided on the Kynshot Hydraulic buffer, lots of good reviews, plus a 1 million round warranty on the buffer.
After some more research I found that I can enhance this buffer system more effectively by adding the following to the items,
One warning, by using the 2 buffers spacers, you will NOT have last round lock back, nor will you be able to lock the bolt back. This is due to the short stoke of the BCG. I prefer no lock back for competition.
With the right combination of custom ammo, a compensator, and the upgraded buffer system, you find that there is minimal movement give great red dot tracking.
All this information and much more can be found in FB, Canadian PCC User group.

Here are the most common systems used from least to most expensive,
- Using a heavier buffer with a flat buffer tube spring
- Odin Works Adjustable Buffer
- MBX Air Buffer Recoil Reduction System
- KYNSHOT 9mm Recoil Buffer HD
- JP 9mm Silent Captured Spring Gen 2 Short Stroke
- Scheel MFG Roller-Delayed Buffer System- Complete System Gen 2

After some more research I found that I can enhance this buffer system more effectively by adding the following to the items,
- A flat buffer spring (optional)
- 2x, 2.5oz weighted spacers (.75” each) in front of the buffer for more weight and making it a shorter stroke
- AR10 8.5” buffer tube to allow for the 2 weights that add 1.5” to the buffer
- Overall BCG and Buffer weight 23.5oz
