A.B.T. Shooting Gallery Rifle Disassembly, Part 4

Almost done…


02161167


Oh, the second socket head setscrew.


02161168


Removed.


02161169


It retains the hammer/trigger assembly.


02161170


The trigger is riveted, so I won’t remove it. The pin could be pressed out to remove the hammer and spring but I’ll leave it for now.


02161171


You can see the spring and hammer.


02161172


Pushing it in.


02161173


That leaves the valve.


02161174


A screwdriver should work as the valve stem can be pushed past the screw slot.


02161175


Removed. No seal on it, although most of the air should just go out through the barrel. Maybe I’ll use some teflot tape although it’s a pretty tight thread.


02161176


The valve stem wouldn’t come out. So I pressed against it through the air supply hole with a bamboo chopstick.


02161177


Valve stem and seal. It’s fairly soft rubber and appears to be in good shape.


02161178


Another view.


02161179


This is what it would look like assembled. I notice there’s no spring to keep the valve seated on the seal, which is curious. I wonder if there’s supposed to be one?


02161180


My bench after the disassembly. I’ll clean it all up and reassemble. I'll spend some time trying to understand better how the mechanism works. Then it’s a question of finding the proper ammo, making a cardboard tube for the ammo, and hooking up an air line.


If you have any useful information, especially a manual for the rifle, original cardboard tubes and ammo, etc. I'd love to hear from you. UPDATE: See here for a source for original ammo.

A.B.T. Shooting Gallery Rifle Disassembly, Part 3

On I go…

02161149

A small setscrew, there are only two socket head fasteners on the rifle.

02161150

Removed and the barrel slides out of the block. The magazine tube is pressed or soldered in as far as I can tell.

02161151

The shuttle.

02161152

Slides right out.

02161153

The lower bar keeps the bbs from falling into the valve, the upper has something to do with the cardboard tube of bb-s that is fed into the gun. Haven’t figured that out yet.

02161154

A screw retains the feed ramp.

02161155

Removed.

02161156

A screw retains that spring.

02161157

Removed.

02161158

The leaf spring that allows the feed ramp to spring up.

02161159

Removed.

02161160

Two springs on the trigger mechanism.

02161161

One removed.

02161162

I left the other one in place, for now at least.

02161163

Large head screw.

02161164

Removed and the feed cam comes off.

02161165

I don’t know what to call these parts yet, and I’m leaving them in place.

02161166

The hammer & valve assembly is exposed.

More to come…

A.B.T. Shooting Gallery Rifle Disassembly, Part 2

On I go.

02161126

The action came out of the housing.

02161127

The forestock seems to have been “repaired” at some point.

02161128

The flap of rubber/polyester/? came loose allowing the bushing to stay in place. This will need a repair.

02161129

That bushing. Notice the red line? I think that’s RTV gasket seal, possibly, which is why the screw wouldn’t come out easily.

02161130

Bushing and the two screws.

02161131

The trigger guard is riveted to the housing.

02161132

The rivet heads.

02161133

The barrel shroud. I unscrewed the magazine end plug.

02161134

That’s a long guide and spring.

02161135

The spring end.

02161136

The screw is soldered to the rod.

02161137

The breech.

02161138

These two screws presumably retain a bushing that aligns the barrel. I removed them but the bushing wouldn’t budge so I put them back in.

02161139

Back to the action.

02161140

When the trigger is pulled it does several things, including moving the feed shuttle up and down.

02161141

The block that holds the barrel to the action.

02161142

four screws plus on that retains that weird tab.

02161143

What is that tab for? Note the screw heads have already seen “service”.

02161144

Removed.

02161145

Four screws…

02161146

All the same.

02161147

Block lifts off of the action.

02161148

It’s aligned by two dowel pins.

More to come…
