In this edition, we’re going to disassemble the Carbine into its major groups.
The first step of any firearm task is (of course) make sure the firearm is unloaded…verify a clear chamber and safety on.
This is pretty easy with the M1 Carbine.
First, loosen the screw holding the front band. The screw is designed so that the rim of a shell can be used to loosen it in an emergency.
The screw does not need to be completely removed, just loosened enough so that the band can move around. On my rifle, the screw was staked so that it would not come all the way out without excessive force.
After the front band screw is loose, Press in on the shaft of the spring clip to release the front band and slide the band assembly forward.
You may need to use a punch or screwdriver to press the spring clip in far enough to release the band.
Then lift the front of the upper hand guard away from the barrel and slid it forward. There is a metal liner on the rear of the upper hand guard that hooks into the receiver to secure it. Lifting the front of the hand guard and pulling forward will pull the rear liner free of the receiver and release it.
The next step is to remove the receiver and barrel from the stock. Simply lift the front of the barreled receiver which releases the rear from the recoil plate which stays in the stock. After the lug at the rear of the receiver is clear of the recoil plate, the receiver and barrel can be lifted free.
Set the stock aside.
Remove the pin at the forward end of the trigger housing. On mine the pin was pretty loosely fitted and didn’t require a punch. It simply pulled out with my fingers.
The trigger housing group is now freed from the receiver and can be lifted clear and set aside.
The first step in this is to remove the Operating slide spring.
The spring is clearly visible on the lower left of the receiver/operating slide.
At the forward end, the spring guide is held in place by a detent in the rear of the operating slide. The rear of the spring is inserted into a deep hole in the front face of the receiver.
To remove, grasp the spring and spring guide just behind the operating slide. Pull the spring and guide back until the tab on the end of the spring guide is clear of the detent in the operating slide.
With the operating slide fully forward and the bolt closed, grasp the charging handle.
At about the point where the forward face of the stop is aligned with the forward face of the receiver, the operating slide handle will reach a detent in the guide track in the receiver and will pull free up and to the right.
Once the operating slide handle is free from the receiver and bolt, slide it back forward again while gently rocking it from side to side.
The final step is to remove the bolt. This is a fairly straightforward procedure, but there are two protrusions that have to be aligned correctly one by one in order for the bolt to come out. One is a rail on the opposite side from the camming lug. The other is a protrusion on the rear of the firing pin.
Pull the bolt slightly to the rear and lift until the front rails are clear of the receiver.
Then rotate the camming lug back to the right until it is horizontal. This will clear the firing pin tab from the receiver.
There you have it. That wasn’t painful at all now was it?
Coming up next: Disassembly and inspection of the trigger housing group.
I keep forgetting to ask…what’s everyone think of my homemade maintenance/cleaning stand and box?
I had been thinking about buying one but I had some scrap wood laying around so I figured I’d just make one for temporary use until I had the money/motivation to go buy one. My homemade one worked out so well I just decided I really didn’t need to spend the money on a commercial one. That’s $30 or $40 I can spend on ammo instead.
