I sent an email to Boyd's to see if they would work with me, for additional money of course, to modify a rimfire thumb hole stock to work with a hooked breech barrel, flintlock sidelock set up. Basically, what I would want is the factory SS Evolution stock from the pistol grip & thumb hole rearwards, and left as a rectangular blank forward of that point to be later inletted by the gun builder for the hooked tang, the barrel, the underlug, the barrel key, the barrel key escutcheon plates, the push button sling swivel bases, the 2 Spartan brass gunsmith adapters, the single trigger, the trigger plate, the triggerguard; and drilled for the ramrod hole.
We'll see what their response is.
I want to put a Rice, 15/16" × 21" long, double taper, 1:14" fast twist, .45 caliber, octagon-round, 4140CM steel barrel, with a Rice CNC machined, flint, Manton-style, hooked breech plug, in a Boyd's SS Evolution thumb hole stock. Pair it with a Jim Kibler CNC machined late Ketland English import flintlock.
As close to a 13" L.O.P. with a Kick-eez Magnum recoil pad installed. Solid butt, instead of the factory normal hollow butt. Normal L.O.P. is 13.75" with a 1/2" thick recoil pad. In an ideal world I'd like to set the stock up with 9 GrovTec push button sling swivel bases. One on either side of the buttstock (2). One in the center line of the buttstock (1). One in the bottom of the pistol grip (1). One on the end of the forearm's center line (1). One on either side of the forearm approximately 1.5" to the rear of the forearm's tip (2). One on either side of the forearm approximately 8" in front of the trigger (2). This would allow for the use of just about any type of sling. Simple carry sling, Ching sling, Rhodesian sling, Riflemann sling, CW sling, any of the various tactical slings.
