I just finished doing a few mods to my Crosman PC77b (the version of the 1377c with black plastic grips & pump arm). So far, I've installed:

1. long (6.25") Crosman steel breech (sourced from Crosman)

2. SS Bolt W/Flow Through Probe (produced by Charlie Mellon of MellonAir)

3. 12" Crosman .22 barrel (recrowned by Charlie Mellon)

4. 6.5" TKO Stage V Muzzle Brake

5. Adjustable Delrin Flat Top Piston (produced by Charlie Mellon)

6. Flat Top Valve (produced by Charlie Mellon)

7. SS solid pump arm pivot pin kit (produced by Charlie Mellon)

8. Leapers 6x32 Bug Buster scope & rings

9. Muzzle Mack Zoned SE stock

I just installed the flat top piston, valve and solid pivot pin last night. I should have a 2289 barrel band on it Monday.

Did you already do work on the trigger? I'm not even close to done with mine yet... It still looks like The Joker's gun... I had a 14" barrel made for it...

How do you like your Zoned SE stock? I have two of them and they are great.
You picked some real nice parts to put together there.
