First of all, official statement of howdy from the great white north. Mid-thirties mom of 6 from Alaska. It's -21 this morning and I'm working on my winter project. My tinkering background is mostly paintball. I play a the local field with my boys and I've got a bunch of parts sitting around from various markers from the last 20 years.
My mitten gun. Started with a 2240 and a budget of $50 or less. So barrel, breech, springs and rest was just parts laying around. Did all the normal valve mods, port etc. Bunny hunting goodness! Still needs a few touches. Fore grip, adj maxflow so I can run it at 1200psi, longer breech probe etc. Fun project, can shoot with mittens or gloves. Going to use a scout scope type mount eventually to make loading easy.
That's a modified WGP hinge frame for an autococker. They are a cheap, 45 style grip frame. Trigger pull is around 1.5 to 2 lbs stock. With the narrow sear top, I was able to put a second notch on the hammer for a high and low power setting. Currently running 900 psi from a 45/4500.
Getting a ton of shots off this tank. Unfortunately my paintball chrono doesn't read pellets.
