Does anyone here know if the flint lock, and barrel from a Lyman Trade Rifle fit in an Investarms hawken stock ? Assuming so, would the Investarms double set trigger assembly function as a double set trigger with the Trade Rifle lock ? Would the Investarms trigger guard still work ? I'm speculating because I really like the patchbox on the Investarms Hawken stock. Thanks to anyone who answers, and The Muzzleloading Forum is the best. I've learned so much from all of your experiences.
