i bought my first "serious" airgun, a RWS model 52 a few years ago (somewhere in the late 80's as i recall) from a now defunct sporting goods store...
i dearly like the feel of the rifle as it reminded me of the rifle i'd trained with and come to admire while serving in the U.S. Army. i soon found that i did not care for the caliber and the severe recoil of a magnum springer it had/has, though and, sort of, laid it aside for a while. but i had managed to harvest small game with it from "respectable distances" (this was in the pre-rangfinders days, mind you, and measuring was done via 'paces' if you'll recall...)
during the 'lull' when it was laid aside there was the purchase of various other springer air rifles and an assortment of air pistols.
mind you...they were not of high, match quality, top dollar airguns but more in the line of upper, utility type, 'bread 'n' butter' airarms intended for casual plinking and putting small game in the pot. after all, i was, at the time, struggling to support a family on a 'working man's' wages. beside that, most of the higher dollar airarms didn't have the 'power' i was looking for (at that time)
lots has happened since then.
i'm now into the PCP, CO2 and gas piston (and still some springers, too.)
my latest "build" is simply doing some 'mods' to the Airforce Talon i recently purchased. it is indeed, a very powerful, accurate air arm with a gread deal of potential based on a platform the average home/garage based airgunner can build from. it's simplicity of design lends itself to the DIY kind quite readily.
i have a garage workshoppe that enables me to do many mods my self, such as modifying the valve of a QB78, but my tooling and knowledge limits me in some aspects at times and i'm reliant on other sources.
but...i enjoy undertaking the challenge of doing what i can, with what i have, to the best of my ability.
