SMITTEN as I've been with far and away the most incredible air pistol in human history, I've felt it would almost be sacrilege to convert my GK into a carbine.
However, having had a jacked-up Steve Corcoran walnut shoulder stock sitting in a drawer for years now, with SC and GK both being of walnut persuasion lead to a leap of logic that introducing the two might have potentials for a match made in heaven. The realization that otherwise the shoulder stock goes completely to waste lead to the inescapable conclusion there was nothing to lose by trying to mate the two. Challenging, work and time-intensive as was the pairing, I'm pleased with the offspring.
Although the shoulder stock already sported a nice walnut grip-cap (with contrasting white accent strip), upon butchering the stock mating surface with the grip that produced the proper angle with the pistol, I felt another grip cap necessary to reinforce strength enough at the juncture to avoid breakage concerns.
With many exotic hardwoods and rosewoods from which to choose left over from my professional bow-building venture, and wanting to avoid refinishing of the stock and grip, both apparently using either no finish at all, or nothing more than oil finishes, I wanted a very dense, strong and pretty wood with plenty of natural oils that requires no finish whatsoever. For those reasons I chose Vera Wood (aka- Lignum Vitae).
A single, stainless steel philips-head screw threads into a threaded insert in the bottom of the GK-1 grip for quick and easy attachment and detachment of the pistol/carbine CONVERTIBLE shoulder-stock. Application of (natural) Tung oil not only completed the project, but brought renewed vigor to the "rode hard and put up wet" Corcoran stock.
Although rains have prevented serious accuracy testing of the convertible carbine, initial test-firting suggests this thing may be the most deadly functional air-powered hunting tool I've experienced in 65 years of air-powered hunting experience(s).
