Crosman Powermatic 500 Disassembly, Part 1

Having hit a velocity wall with the V-350 I decided that a slight change of pace was in order. So I dug a Crosman Powermatic 500 out of my pile of airguns.
Not a bad looking rifle, with the same lines as most other Crosman air rifles of the era.

It has an inline BB magazine above the barrel.

There’s a bit of corrosion.

Power Matic 500

More corrosion. This isn’t inspiring confidence.

This is where the CO2 cartridge goes, The plastic plate which hides it is missing.

As is one forestock screw.

Time to begin by removing the buttstock.

The stock is really heavy. I believe that this is a Croswood stock.

Removing the one remaining forearm screw.

The knurled CO2 nut needs to come off.

I clamped the nut in the vise to get the punch started on the roll pin and then removed it so I could rotate it 90 degrees to fully tap it out.

Notice that the forearm isn’t lightweight like a plastic part – it only has enough material removed for the parts to fit in.

The “barrel” band holds the shoud to the stock.

I removed three screws.

And carefully separated the halves. Nothing shot across the room, which is always a good thing.

As you can see the innards are corroded and full of cobwebs.

I took a bunch of views to make reassembly easier.

Notice that the safety is missing.

Another view…

Not really that complex although I’m unsure how the mechanism works.
More to come…
