Basic Strip Down... Hudson M3A1 "Grease Gun"





Hudson’s M3A1 is a very simple and easy gun to strip, dismantle and maintain. Just like its real life counterpart, it was designed to be a solid and reliable weapon capable of being taken apart and maintained by a soldier in the field with the minimum of tools or fuss.
In fact, this modelgun can be field stripped without any tools at all other than one Allen Key.
The gun uses its own skeleton stock as a dismantling tool so it couldn’t be easier!
A Philips (Cross Head) screwdriver will be needed to remove the Bolt from the Carrier for thorough cleaning and inspection of all its components.

Cleaning and Re-assembly are described in separate Step by Step Guides so this guide begins with your Grease Gun in need of dismantling after firing.

Inspection of parts for damage will be dealt with in a separate Guide.


Step 1. Removing Stock

The skeleton stock is collapsable and pulls out of channels running along the length of the receiver.
It is locked in closed or extended position by this spring loaded button...







To extend the stock, push this button to allow the stock's arms to slide outwards. It will lock in the extended position so a further push of the button is required to allow the arms to pull free.

Step 2. Barrel Removal

The barrel is secured by a threaded cap. Pull the spring catch down a little a unscrew the cap.






Pull the barrel assembly clear.

Step 3. Removal of Detonator Chamber

Using the stock as a tool, insert the stock “rods” into these two holes and unscrew the Detonator Chamber from the Barrel, see photos...














Step 4. Removing Detonator Pin

The metal Detonator Pin is secured by a grub screw into the plastic Detonator Chamber.




Remove the screw with an Allen key and push the Pin out of the Chamber…

Top tip.. This Top Tip was added to the thread by fellow forum Member Kickback 24/12/07... When you put the greasegun back together leave the grub screw that holds the detonator pin out, apparently this prevents the chamber from splitting which is a common fault with this model.





Step 5. Bolt, Bolt Carrier,Recoil Springs and Guides Removal




Simply squeeze the trigger to depress the Sear. This frees the Bolt assembly and just requires a gentle push against the 2 rods sticking out of the back of the receiver.




The Bolt, Recoil Springs and Guide Rods will come away from the receiver tube complete.








Pull the Bolt and Carrier down the rods against spring pressure and hold the Bolt about half way down...

N.B. This photo shows both Spring Clip and End Plate already removed. They would both be in place at this stage




Remove the Spring Clip...




Remove the End Plate...




Slide the Bolt & Carrier assembly back up and off the two rods...

The Bolt should only be removed from the carrier if essential repairs or thorough cleaning is necessary. The screws used thread into moulded plastic which is prone to excessive wear.
However, when necessary, remove these screws...




Lift the Bolt away from the Carrier...




That’s it… the next step is
