Check on the drop/fire issue. The 85 can fire if dropped. Factory used to fix them. Look for 2 dots under the safety lever to indicate if it was upgraded.

That's a pretty good deal on a very good rifle. Probably because quad rails are out of fashion, but even then the DD quad rails are pretty low profile and nice to use
