2260 with short crosman receiver atop a mini riser made from aluminum tube. Barrel is a 2200 soda straw
tensioned inside a titanium golf club shaft. Three screw mod to the trigger, bulk co2, SSP 250 rear cocking
striker assembly. Factory stock, reshaped, bedliner finish and stick on cheek piece. The idea was a weather
resistant light hunter for rainy days.
I've got a Cothran stainless receiver and gas tube waiting for me to get back to this one.
..but I wasnt suggesting using it in a crosman. I was thinking some kind of specially made combustion chamber behind the breech into which the pressurised oxygen (Or maybe NOx) could be injected trough a non return valve. As an engineer caseless fuel/ammo and an oxidising gas seems like an interesting concept for a rifle to me...but I guess there must be a reason why noone makes them already.
The petroleum jelly in a spring/HPA rifle does work well though, you should try it.
