BSA R-10 R10 regulator anti-tamper XTX

One way of removing the anti-tamper cap from a BSA R-10 regulator. This allows you to gain access to the regulator so that you can remove it to fit a HuMa regulator.
Don't exceed the power limits for your country.
Do it at your own risk and I accept no responsibility if you damage yourself or your airgun.
If in doubt send your airgun to a professional.
