I have a friend that picked up a Savage 10BA and wanted to use a Larue QD mount on it (specifically the OBR LT-111), but it seems the rail isn't 1913 std. He's been going round and round with Savage and they swear it's in spec. They've even sent him a new rail which still won't allow the mount to attach when he tried it today. We've tested the Larue mount on an AR-15 and it had no issues. I just want to see if someone out there has tried this and if they were successful. I feel really bad for this guy as he's had this rifle for close to three months and hasn't even put a round in the chamber because of this problem. Thanks if you can shed any light on this situation.
