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.

Response to Yup. Cuz' what holds the checkvalve open isn't the pressure...

for flattop valves an piston, and the ICV.

1 full pump, like from 10.... yikes thats 10% loss just to crack the valve.

oy.... the 1377 valve doenst have the shelf like the 39x valve do to hang the ICV hardware on. Soooo... drill out the valve the create the shelf from the valve body,or drop a small it of tube in.......

And I'm going to suppose that the size and shape of the check valve itself has little bearing on the opening forces required.....
