Marushin M1 Garand Airsoft Gun Clips, 6mm, Updated 8/1/22

Edit 8/1/22: New reworked design with fewer parts.  New channel internally, which feeds BBs more reliably.  New lips which help prevent double feeding. New follower design for more reliable clip ejection and easier loading. Decorative back design added.

Edit 3/27: Updates made to dimensions and instructions.

Spare 6mm airsoft clips are hard to find for the Marushin M1 Garand collectors airsoft gun, and expensive! Now you can print as many as you need!  These plastic clips are significantly cheaper, can be sacrificed if lost in the field, and offer improved dimensions for better feeding/ejecting in the airsoft gun.  Works only for the Marushin M1 Garand airsoft gas blowback rifle with 6mm BBs only.

The clip “wings” are tuned to fit better in the chamber without interfering with the striker rods.  The original metal clips sometimes jerk against the valve knocker responsible for BB propulsion.  The tuned dimensions of this clip makes it significantly easier to insert, sit securely, and eject with less contact with surrounding hardware.  

This is very easy to print, with no supports necessary.  Print all 4 parts with the flat side down.  PETG offers good durability/flexibility to resist breaking when the clips fall on the ground.  PLA works as well, but is brittle and the wings often break on impact with the ground.  You may find a .25 nozzle will offer better print quality, but this print should work fine with a 0.4 nozzle on a MK3s+ with default settings.

Assemble with 4 M2x6 or M2x8 countersunk screws and a spring approximately 45mm long, <6mm in diameter.  I found the best so far are sections of spare Hi-Capa magazine follower springs, available as aftermarket upgrades from brands such as Guarder.  Their dimensions and spring rate is perfect for this application, and are widely available as spares from airsoft retailers.  Cut about 8 or 9 rungs or so, enough to apply pressure on the follower at the topmost empty position, which will give enough force to trip the Garand ejection feature.  Midcap and round springs may not work, due to tolerances and spring rates.  Simply insert the follower and spring into the main body, close up with the front housing on top, and screw together.  Check the follower moves smoothly in the channel.
