just a quick video of how to remove the anti tamper bolts on the s400 mpr. air rifle
tried a few anti screwdriver bits, but didn't have the correct on , so tried using a screwdriver to remove them
its so easy to do, thought I would share with other airgun users
.now they are removed its so easy to do my own repairs on it should I have the need to.
the anti tamer on the power side has been removed to adjust the power also, that's a simple job just drill out, with drill bit and it will be easy to adjust power,
mine was 5.10ft ILBS on the chrono, so now adjusted to 4.9 for indoor use, and also tried to power up, I took it up to 11.99, to see how much power it can produce, lets just say there was plenty of adjustment for more should people with fac licence, I'm sure it can go higher than 12.

also a quick tour round the workshop
thanks for looking and hope this useful to you all
