I just put 1 on an XP-100 20 BR for my main coyote fur-getter this yr. It's the 3-9X 32mm 22 LR scope/reticle. I like their reticles so we'll see how it goes shortly. Sort of a mini-Horus Vision system. I especially like their 600LR reticle. Seems like a nice scope-- 1 piece aluminum body-- parallax was minimal on mine out to 400 yds., 1st focal plane reticle. So far i'm quite impressed. Jacob Gottfredson did a writeup on them awhile back for PS magazine, and liked them. Here's more-- www.rapidreticle.com
