M15a4 screw size help!!!

[gaven555]

I have a classic army m15a4 and i need too get too the gearbox, but as i understand the gearbox is enclosed by the body of the gun which is held together by two screws. My problem is that i do not have the right sized screw driver to get these screws out and i do not know which sized screwdriver to purchase. Thats where i need input

Thanks for your help! :cheers:

Are these not front and rear receiver pins that need to be driven out? Everything else can be done with a #1 and #2 Phillips screwdriver.

If you have Allen head screws in place of body pins, just a standard metric set will suffice.

In America We use a different metric i'm sure thats why both my differn't sets of Allen screw drivers wont work.

Dude, there is only one "metric" system, its an international system that every country in the world except the US uses, you dont have a different "metric" (1mm in Canada = 1mm in Japan = 1mm in Germany) you have a different measurment system called the "imperial" or "british" system. You need to pick up a set of metric allens, you most likely have imperial ones (their measured in inches right? metric is in millimeters) shouldnt be too hard to find at the nearest hardware store, if not there try a small engine repair place.

Mine used a hex set to get that out... costed $5 for about 11 of them.

I think the size was 1/8.
