Hi there I have a aa tdr in .22 flavour with a custom 510 action done by a&m gunsmiths I'm either wanting to convert it to .177 or swap with someone for a .177 tdr I would be willing to add a little cash my gun is like new with 2 mags . As for the conversion I can get a .177 barrel what else would I need to get and do ?

So it's a 510 converted to TDR? If so it's pretty unique.
Surely this'll be quite easy to sell to finance a .177 TDR?
If you go down the cal conversion route I believe it can be quite expensive.

No its a tdr that's had a 510 action put on it . Lol so then yes I guess it's a 510 tdr . I have sourced a 177 barrel and magazine for £60 and someone says the pellet probe is the same but then if it isn't can it be machined down to the right dimensions? Thanks

You could machine it down, but why bother, just get the .177 probe S540A-SL, then you could go back to .22 if you felt like it, you will also need .177 bolt hse bush S 502-SL and the detent buffer S142. Rog

You can order the parts from julian just leave a message on The spares page.

Hiya, did you get this sorted? I'm in exactly the same boat. I have an s510 Tdr converted by A&M in .177 and I want to change mine to a .22!
