shade tree garage tuner
an average guy who likes airguns has a spring compressor a little knowledge of how to use it and disassemble guns. Likes to go in relubing what’s there or drop in a premade kit.
cost as minimal as it’s usually lube or the cost of the kit Itself from the manufacture
$25 to $100
Level 1 pro tuner. Getting rare ,but a few still exist
A tuner is a person qualified at Tuning a gun with a new guides and a custom top hat and a custom spring ,
filing smoothing adjusting the cocking slot. buttoning , Or glideing the piston ,making custom seals Or any part that’s needed. basically take a stock gun and take it to the best shooting range , not the max power..
I have been doing it for over 25 years , on select guns I own, and there’s some guns I still struggle to get it where it needs to be even if you do the same thing. Every gun is different and you have to use all the knowledge you’ve learned through the years. Take good notes on builds and date them
anywhere from $100 to $500 cost. Depends on the tuner.
Level 2 gunsmith. RARE AND ALMOST EXTINCT.
A gunsmith is a whole different ball game. A gunsmith manufactures parts and can make his own gun. Complete compression tubes breach blocks and cocking arms pistons and any other adapters needed. They also can do complete stocks and finishing of them. A gunsmith doesn’t need a factory gun to start with but may reuse certain parts because it’s easier when making your own gun to use parts as breach blocks trigger mechanisms and such. Usually barrels are hand selected. Each gun is bespoke to a specific customer or goal.. Each gun is one in its own there are no two alike..
stars at $1000 and goes up. Sky’s the limit on customers desire
I will post up a link in the next day or so of the brand new gun I built from the ground up and it specs
