I've had a Custom Shop since about 1994, a very early 1/8th click 8-40x; it's fantastic, great image, great ranging and totally free from temperature variation. I've looked through loads of other CS but none touch this one - it even has slightly different colour lenses. Shame the elevation turret is knackered but I've sent it to the states to get fixed.
I've also got a 10-50x Deben DMP, a pre IR model and this is also excellent, though I have not used it enough to determine just how good it is, though signs are good.
I've just bought a 32x PR MK 4 Ultra off fleabay of all places, it's mint and the image is knockout. the focus and ocular adjustments are so smooth that they make a mockery of all the other scopes I've owned. I bolted it on to a TX yesterday just to see how it ranged - within 1mm of the mark on a 6 inch wheel at 45 yards. It's a pleasure to use - I hope it's good enough at long range because I would love it to be my comp scope.
Best Regards
Simon
