Basic Tuning Tips... Hudson M3A1 "Grease Gun"



***UNDER CONSTRUCTION***


Top tip..

When you put the Grease Gun 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.


Try substituting Hudson’s own cartridge Piston with MGC ones. The MGC type do not have a hole drilled through the piston centre and may well seal in more gas pressure as the cap ignites giving much better blowback.
Note, however, the Detonator pin will have to be shortened to suit the MGC piston’s extra length.

This photo shows Hudson's piston on the Left, MGC's on the Right...
Note difference in overall length.



This one shows the hole drilled through the centre of Hudsons' piston...
