Classic Army M249 parts questions.

Hi SharmanAJUSMC,

I've had the exact problems you are describing regarding the piston.  You can view that in a thread here

I run an M120 spring, Systema Super TorqueUp motor, and 9.6V 3.8Ah Batteries.  

I'm considering a stronger piston, but I have concerns that making the piston too strong creates a situation where the gears may fail instead of the piston.  I prefer to replace a failed piston(single part) vs having several gears fail.

Let me know your thoughts...

Just go get a new piston guys, your choice, its a part that can break and needs to be replaced. I'm sure there will be several different brands recommended to you. FACT: Parts may/will break & parts can be replaced. Why do companies that make parts exist?

Deep Fire is the piston to get.

well i am planning on getting the deepfire piston with the full metal teeth, i have been told and read on the internet that the stock piston with an above 8.4v battery will definately break, so im going with a deepfire piston and i havent decided what piston head i want to use yet, not a metal faced one for sure, im thinking perhalps the guarder polycarb with the bearings.

is it hard to take apart the gearbox? i dont have a ton of experiance with that, but it looks alot easier because you can take the main spring out first.

Piece of cake.  yes take out the spring first.  then nothing is really under much tension except the little spring for the anti reverse ratchet and the selector spring  by the trigger.

I can take more pics as I assemble mine if you like.

i would love to have some pics of you assembling it, i havent gotten my 249 in the mail yet, but its commin soon, and i would love to have pics for reference since the first thing i do is going to be to change out the piston and main spring. ]
