View Full Version : MR1 Expansion Chamber

i noticed that the threads for an expansion chamber are different for mr1 series and i was wondering if they made an m16/m4 style expansion chamber that would fit an mr1, ive seen people that have modified their markers with an actual magazine from an m16 but i would rather not have to drill holes in my gun and do sanding heh, thanks

honestly, the mr1 doesn't have an expansion chamber. its just a foregrip covering the hose, but i know what you mean. you could get an adapter for standard regs, and put a RAP4 magazine expansion chamber on there, but it would look ugly because its not flush with the body.

If you just want the look, you can do some research and find a magazine thats somewhat compatible. You would have to mod it to fit (Dremel)

either sportsmansguide or cheaperthandirt has AK mags for $17. m4 mags should work too. i measured my dad's and its just slightly slimmer than a spyder body.

:yeahthat: you would still need a 1/8 NPT to standard CA (forgot the thread rating) adapter.
