Crosman 38T and 38C power mods

[Septicdeath]

Five easy mods for your 38T or 38C

1. Drill the sleeve around the spring into swiss cheese like pattern. Creating more co2 volume

2. Open up the exhaust port. creates more flow.

3. Shim the magazine for a tighter fit to the valve
body

4. Adjust the barrel so it just barely touches the magazine but dosen't bind. Stopping some of the loss of co2

5. Relocate the hammer spring guide pin to re-arch the spring, or a stronger hammer spring to open the valve a bit more when the hammer engages the valve.

JGairguns will have them. But they require $15 minimum purchase. You also will need to make a account.

I bet mods 3 & 4 above would increase the shot count per cartridge.

I thought I'd post a picture of the valve sleeve mod.

FYI, the law requires companies like JGA to gather proof of age because some airgun parts are considered Firearms in IL. That's why companies require an account.

Glad you shared that, your earlier explanation had me lost
I'm waiting on a seal kit to repair an older 38T (metal rear sight, metal magazine) .22 for a customer.
