Knoxx Stock and IPSC

I have seen a lot of discussions about the use of the Knoxx recoil suppression stock in IPSC competitions. Some shooters believe that it is prohibited under this rule:

22. External modifications such as weights, or devices to control or reduce recoil are specifically not allowed, except for recoil pads fitted to the rear face of the stock of the shotgun.

Other think that it can be installed because it is not an “external modification”.

I decided to contact the IPSC at the rules@ipsc.org to find the answer. I was very pleased to receive answer from Neil Beverley, IPSC Shotgun Director. And now I want to share the truth about use of the Knoxx stock in IPSC.

“Knoxx recoil suppression stocks can be fitted as a direct replacement of an existing stock under Point 23 of the division rules.”

“Point 22 of the rules prevents any additional weights from being added externally to a stock.”

Also, Neil sent these two links to the IPSC Global Village where you can find more information:

So, the short answer is Knoxx recoil suppression stocks CAN be used in IPSC.
