I had a Leupold eer 2x handgun scope on a pump action .22lr for years. It was fun as hell to shoot but that particular .22 was a low quality Taurus model 62. worst barrel I have ever seen. It didn't shoot worth a damn. Long story short I loved the scout scope and hated the rifle so it is gone. I did find it very fast for target acquisition and I have thought about trying it out on my AR. I'll post some pics sometime if I do.
