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.

9mm Discovery based valve gives over 80 foot pounds

The most powerful gun I have ever built.

Barrel is 14" with a 13" stainless air tube.

The valve was located 1/2" farther from the end then the normal Crosman location, so the hammer stroke is a full 1/2" longer.

The Disco valve was highly modified in pretty much every way possible.

The spring is .041 and 1 1/2 longer then the stock Discovery spring.
Has a Don Cothran rear cocking kit, with my own custom hammer.
The frame is phase 3 with an adaptation of the PPG phase 2 drop sear system.

The port seal is 5/16 poly.Surprised me with this power, as I had been using 3/8 poly tube for big bores....but the thin wall of this 9mm barrel prevented it's use.

I credit most of the huge power to the hammer / spring system, it really opens that valve and keeps it open more than long enough.
I think this gun could use a lot higher starting fill pressure, but I am limited to a hand pump...........scuba tank some day !

Shot string with 77.8 grain eugin and 3200 psi fill is :
Shot 1. 685 =81 FPE
shot 2. 630 =68 FPE
shot 3. 597 =61 FPE
shot 4. 465 =37 FPE


YES, THIS IS FOR TO FILL A CURRENT ORDER....before you guys who are waiting on a 9mm start emailing me.....the one who this is for will be contacted tomorrow with a tracking number.
