Dag Evert's "American Classic"

As mentioned on the forum, heres a picture I took some time back, with natural winter daylight.
A 2100, and a 1377, both guns have been recrowned, and had their trigger parts shimmed for play,
contact surfaces stoned, and trigger springs somewhat reduced within safe limits.
The 2100 has had its barrel shimmed with tape to remove play.
Both guns give great accuracy for the money if they are given good pellets!
The combination of pellets and guns in the picture represents something close to my boyhood dreams:-)

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.....
