Crosman 2200 Magnum SE Pro Stock
« on: December 17, 2019, 09:37:10 AM »
Picked up this 2200 Magnum Silver Eagle on EBay earlier this year.
Won't pump up and the stock loops were MIA.
The gun is in good condition otherwise.

The plan is to upgrade the pump engine but leave it appear original.

It'll get a FT piston/valve, seal the TP and probe etc.

Took the gun apart and found a brass restrictor in with the TP seal.
It's .125" and listed in IPB so a stock item.
Seems like this would limit the power, interestingly it's only in the phase 1 guns.
The valve port is .155" as is the barrel port so the restrictor will be sidelined on this build.

The stock on the early 2200s is a dark chocolate brown.
I could have swapped the stock out for a later lighter brown version but.....
Decided to fix the original, so after some thought came up with a fix.
Machined some brass and soldered them together.
Then glued them in place with construction adhesive.
Should be much stronger than the original plastic loops.

The earth rumbled, the dam broke and this flood of parts spilled out....LOL

Have a few more parts to make but the heavy lifting is done.

These are the rest of the parts made this morning.

Got some trigger time today....LOL

This mod will eliminate most of the creep and allow the gun to be decocked.
Removed the interlock and replaced it with a Delrin spacer.
Added a brass extension to the sear with a 6-32 adjustable screw.
It's pressed on (actually tapped on with a hammer) with some construction adhesive as added insurance.
I'll get a set screw this weekend when I'm in town.
Could drill a hole in the receiver to allow adjustment in the gun but not on this classic.

The later 2200s and the 2100 have a different sear but can still be made adjustable as done here:

I have a Model 1 where someone wrapped aluminum tape around the hammer to limit the sear engagement. Didn't work too well, so I removed it. Maybe I should try again with more tape!

I've seen o-rings wrapped around the sear etc, JB Weld works good on the hammer.

Speaking of JB-Weld, you can get it in the Pro size 5 oz tubes.

Added a felt wiper to the piston.
The retainer is a recycled Delrin piston, left the o-ring on it.

Bedded the front of the receiver with JB-Weld to hold the pump tube and shroud solid.

Nice work! Have you tried this sort of thing on a S&W 77 yet?

More valuable still are the ones who go to the trouble of making me see it.

I had to google the S&W 77 as I'm not familiar with it.
I work mostly with Crosman guns since parts are easy to find.

Do you have an S&W 77?

The trigger had too much first stage travel and was too heavy.
Took the first lobe off the sear and ground the second lobe down to .125" from .150"
Contoured it to look like a great white shark fin....LOL

Cut the sear spring from .800" to .500" to lighten the cocking cycle and let off.
Took a little tension off the trigger safety spring.
Now cocks smooth and has a short first stage followed by a nice light crisp second stage.

The brass bolt looks really good against the chrome receiver.

I was test firing the gun without a pellet loaded and it shot out the TP seal.
Undaunted I decided to chrony it anyway.

With 14.3 grain CPHPs:
03 pumps= 407 FPS   05.26 FPE
05 pumps= 513 FPS   08.35 FPE
07 pumps= 605 FPS   11.62 FPE
10 pumps= 676 FPS   14.51 FPE (slight amount of retained air)

Good numbers especially from 3-7 pumps.
I'll retest after it gets resealed.

Nice numbers, esp. with a leaky t-port!

Loving the sear mods and bolt handle!

How does removing the first love affect things?
