I have an opportunity to possibly aquire a remington XR-100 in 223, i did a little research on them and they seem like a pretty cool rifle. would be a good platform for a varmint rifle build down the road. My question is, does anyone have experience with them? what actions is it? i think its the same action thats in the xp-100 handgun isnt it? and isnt the xp-100 a remington 600? or am I mistaken? any info would be very appreciated.
