Sorry guys, I just can't resist showing off the latest acquisition. It's an M77RS 243 with the Slotted front sight ramp and it's NIB. The slotted front sight is one of the rarest features to be found on a Flat Bolt M77RS (or S - Sights - no rings) and show up in the 70-0xxxx - 70-10xxx range. This rifle is the highest serial numbered slotted sight I have seen, 70-10491 and I've only seen 5 or less M77's with this feature in 30 years. I owned another M77RS 243 with the slotted sight serial number 70-08758. Slotted sights show up more frequently on early No.1's in my experience. I 've never seen any other caliber with the slotted sight besides 243 and 308. Also of note is the straight wood under the eject port, another feature to watch for in this serial range.
