I have a feeling they do two very similar scopes. Mine is the 3-9x40 AO, so adjustable parallax. Goes down to about 10 yards if I recall, without running to gun safe! At 3x and min parallax I was able to see well enough to shoot two ferals at about 3-4 yards a couple of says ago.
The only oddity is that the turrets adjust to 1/4" at 50 yds, rather than 100. The scope was designed for .22 Rimfire and airguns, but IMO it is just great for .22 at 12fpe for 'farmyard stuff.' I don;t think they are easy to get in the UK tho, but if you have trouble, PM me and I will dig out the details of where I mail ordered mine from in the UK.
Everything about it is nicely made. The parallax adjusts smoothly with just the right weight. The turret caps come on and off sweetly with no threading issues. The click stops are snappy and clean. Optically it is a fair bit better than the MTC Mamba Lite so that does help when knocking ferals out of barns in low light. The fine reticles with the little dot in the middle is very precise. Perfect for bopping a barely visible birds head poking up above a rafter and precise placement.
