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 Ok, here's some numbers, this is maxed out,

........especially in .177. Performance is remarkable - hows the cocking effort?

Update:

I read your post on the yellow (can't post there yet). Thats cutting edge stuff for sure.

I think what we're looking at is....FT = MV. Since the valve is low volume then time is not your friend. To max out V for any given M, F or transfer pressure becomes critical. It looks like you've hit a near perfect balance between the compromise of flow rate and transfer volume. Also, the heavy's should outperform (fpe) because of two reasons. A slower acceleration due to higher mass will give the FT side a boost by allowing the force to stay higher for a longer time; also, there is always less energy loss with lower velocities. Going forward, I wouldn't know how to improve (efficiency) if you've already eliminated or minimized all transitions (size, shape, direction) in the transfer.

Awesome!
