Scot Laughlin's Custom All Weather 2260

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.

Thanks Chuck, the down side is now that the compression side losses are being eliminated

Response to even better.

the closing force on the pump lever is 56 lbs! The other side of the equation is eliminating transfer port losses which can pretty easily be 1/3 of the firing chamber volume, because the firing chamber is so small, which means you can loose 1/3 of your pressure befor the air reaches the pellet. I think I've got my losses cut to about 1/5.
