Marushin MP40 (ABS) Strip down and Cleaning
When I bought my first model gun I had no idea how to strip it down for cleaning and inspection. On-line help from forum members here got me sorted so I thought it might be a good idea to post up a Step by Step guide for Beginners.
I would welcome your thoughts please chaps. Most of the regular contributors here are far more knowledgable than I am. This Section is intended for Beginners and covers the basics. If you think I'm wasting space, please let me know ok?
As a sample then, I'll start with the Marushin MP40...
Step 1.
Remove the Magazine... Ensure the Bolt is all the way forward...
Unscrew the Barrel Nut, pull off the Barrel assembly taking care not to drop the Sling Loop and Washer.
Step 2.
Cleaning the Detonator Pin and Chamber is vital to keeping your MP40 firing properly so:-
Using long nosed pliers grasp the Detonator Pin and pull it out of the Chamber
Step 3.
There's a slot cut into the Barrel tube...
Grip the Detonator Chamber with your long nosed pliers through this slot and pull the Chamber from the Barrel. This can be stubborn but grip it firmly and ease it out...
Step 4.
Next step is to seperate the Upper and Lower Receivers to get access to the Bolt assembly and Recoil Spring.
Pull the Locking Ring downwards away from the receiver and twist it half a turn to lock it in the release position. The Spring here can be tight and awkward to pull against. If needed, remove the 2 slot head screws securing the side plates to the gun and pull them off. The Locking Ring is now fully exposed and can be turned easily.
Step 5.
Grasp the Upper Receiver around the Magazine Well with one hand, then grasp the Pistol Grip with the other. Squeeze the Trigger and keep it down while you twist the Upper Receiver clockwise. Twist it round until the rear sight touches the Lower Receiver side.
Step 6.
Pull the Upper Receiver away from the Lower Receiver.
Step 7. The Bolt and Recoil Tube are a slide fit inside the Upper Receiver so to remove it just grip the Cocking Handle and pull it back and out along the slot
A strip down this far will enable you to clean and re lubricate your MP40 ready for re assembly.
Next Chapters will cover cleaning, inspection and re-assembly...
