I found one on EBay cost me £20. For club shooting and single loading it’s easier than removing the mag each time. Plus longer range shots it does improve accuracy

Just bought one of these for my Ultimate Sporter in .177. All I can say is it’s brilliant. Brilliant brilliant brilliant..
Perfect pellet to barrel. Slick as a slicky thing

My other thought was to use a dremell with a thin grinding head to put a small notch in the pin down the Allen bolt hole. The flat screwdriver in the slot and lever it.
The .22 TDR is a tack driver and has so many rabbit and squirrel to its name. Hope it serves you well

Put them in. So positive on the magazine. No worries
Enjoy the TDR. Nice rifle

Nice to do business with you Rog. It’s a great looking/shooting TDR, it will serve you well
Shame about the other pin not moving

Pictures sent

I have one just sitting in it’s pack. Brass rear bolt Fitted by previous owner.
Shoots jsb heavy pellet on pellet. Beautiful markings on stock. 1 mag. A couple of tiny marks from case rub where butt section touched cylinder. Shoots absolutely spot on
Located in Kent

Positioning of the magazine is perfect every time with the upgraded post. I have 2 mags for the US. One is well used the other is new. The old one worked with the old post but new one didn’t. I had previously bent the steel spring and had to reshape it hence the issues with the new one. Upgrade goes...

Just changed the indexing post on my ultimate sporter from the bent metal spring steel one to the new hooked brass one with a spring. Oh what a great mod that is, no missed turns on the magazine and central every time.
Should of done it ages ago
