Air Arms S410 TDR PCP

[T-oddity]

I have a Tdr, fine air rifle does the job, it wont work without the butt fitted, a requirement to keep it legal, don't know if it is possible to modify, but to be honest I don't see the point.

I recon if you wanted to have an over powered air pistol you might as easily uprate an off the shelf pistol with far less hassle.

An alternative that I have done in the past is to mod the Crossman ratcatcher, the butt can be replaced with just pistol grips and there is plenty of info on line about tweeking a Ratty and plenty of parts available.
I moded one to have a removable butt for back packing and it was not intended to be used as a pistol, but still illegal never the less, very easy to revert the mod for general use though. I have some pics of it floating around the internet either from years ago I will try and track them down and post them up.
