Carl Quick's LiteWieght 2240

So for about the last 24 months, I've had her on a serious diet. Now I am happy to report that she lost nearly 13 ounces and is feeling so much better. And let me say one thing, when I pick her up with one hand now she is light as a feather. Well, almost a feather.

Things I have done so far:

OEM main tube was lightened by me.
Barrel is OEM and trimmed down by me.
Main tube plug is made of Delrin by me.
Gas cap is aluminum, comes from HPA and bored out by me.
Hammer is made from Delrin by me with a modified 1701P striker.
Valve is an aluminum Disco rear end with a brass Pro-Top by Anthony.
Trigger grip frame is aluminum by Bluefork Design and then hogged out by Gregg.
Front barrel band is aluminum, made by Anthony, drilled by Rich and milled by me.

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.....
