Looking For A Gundoc in the Lower Mainland

[Neogio]

Hi i need to find a gundoc to help me install a metal hop-up into a TM m4

these are the steps needed from what i gather

1. Slide assembled hop-up chamber/barrel in to your outer barrel
2. Slide gearbox in to the UPPER receiver - be careful of the rear tabs of the upper receiver! They may get hung up on the bushings of your gearbox. Use a screwdriver to GENTLY pry the tab up at the base of the receiver to lift it up and over the bushing. DO NOT lift the tab at the tip or you might snap it off.
3. Slide the lower receiver on to the gearbox - you may need to fiddle a bit to get the front of it over the hop up chamber
4. Insert body pins
5. Insert small pin above trigger
6. Install magazine catch
7. Install pistol grip
8. Insert motor & grip end pl ate
9. Install buffer tube & stock

if anyone can help it would be greatly appreciated

thanks, Gio

U need to modify your lower reciever to accept the metal hopup, since your going from a 2 piece to a 1 piece

Yes i understand that it must be modified with a dremel tool
