Jim Gillilan's Custom 1322 Carbine w/Custom Stock

Here's one I'm especially proud of and is modded all over, doing 12fpe at 15 pumps.
Stock is Teak from Thailand and super light weight 1322 Carbine!

Response to 1377 to 1322 upgrade, my results. Need stronger hammer spring?

On 15 pumps with the mods below I was able to get

1377 15 pumps - 750fps
1322 15 pumps - 650fps

Flat top
lighter valve spring
heavier hammer spring
24" barrel
trigger mods
Didn't want to mess with the port

I had fantasies of getting 1000fps, somebody may be able to do it. I stopped and am happy with were they are. Acuracy is great and shot placement counts for alot.
Cleaning and oiling the barrel can get you abit more fps.
Have fun
