My guess based on the magazine is that is a BLR-81 (steel receiver), only slightly different from the earlier BLRs and substantially so in the the magazines for the BLR-81 are relatively easy to find. The original BLR magazines in contrast are much more uncommon and thus much more expensive. Excellent rifles in my experience.70s model browning blr 257 Roberts. Good shape but has been shot. Leupold limited edition 3-9 with bullet drop reticle. Very good gun. I got it from original owner. $1000 and it can be yours!
