Ok, so for a firearm, something in lines of wire and tension,So something to adjust the trigger pull?JR
My first guess was valve extension or valve tool....then you said firearms....but the trigger is not exactly in the "area" of sights...so not sight adjustment....Perhaps a tool for disassembly...but you said not for fasteners?I got nothing.
For an AR15?
S&W rebound slide spring tool..
Got it first time!Didn't even have to look up every brand of NA firearms and search through them for SSTs....
Another classic high quality picture from Sea Monster.....
It's for hauling up your packed lunch from the deep cave you keep it in to hide it from other sea monsters.
A Sail Makers Hook or Bench Hook?
