Select fire conversion for M249

Recommended Posts

Has anyone managed to add semi-auto functionality to their M249? I'd love to have the option to roll into the back of the stack after providing suppression. :)

You would need to completely replace the gearbox, as in rebuild the gun take a V2 or V7 gearbox.

 

Or buy a support gun based around a V2 gearbox like a Shrike or something.

The stock M249 gearbox is very basic inside, no cut off lever or trigger trolley, just a microswitch turning the motor on and off.

G&P M249s are based on V2 gearboxes. You could probably add semi auto functionality there with ease. If you allready have an A&K it's still possible with a programmable mosfet, no way to add a physical switch tho.

On a G&P M249 you might be able to get away with it with say a Gate Titan for V2, since it use a V2 mech.  You could program a 2 stage trigger for a selector.  

Otherwise, other 249s might be a bit difficult.

I recall seeing a guy at my local field using a CA/clone Minimi with semi auto. He appeared to be using the safety as a fire selector. Any idea how that might be possible? I'm sure it's some sort of digital fire control, but I'm stumped beyond that point.

 

I wonder if I could program the WARFET installed in my Minimi to help out with this little project.

Most programmable mosfets detect the one turn of the sector gear with a microswitch against the little nub that normally moves the cutoff lever. You could adapt a mosfet to the m249 layout for the cutoff function.

Same goes for the selector switch, its just a microswitch that needs to be tripped, the safety bar could do that if you place it right. 

Shame there is no ready made solution for this as far as i know but it can be done with a bit of soldering and tinkering.

The Gate WARFET is outside of the mechbox, so I'm not sure if it could be modified to add semiauto to an otherwise fullauto-only gun. I'm not too keen on buying a bunch of new stuff to get this to work, especially not a whole new gun or expensive MOSFET.

Well there is no easy way to do this, the A&K gbox was never intended to have this feature. A Gate WARFET wouldnt work. You have to have some way to detect a cycle and the WARFET depends on the cutoff lever to do that. Since a cutoff doesnt have anything to "cut off" like in a v2 gearbox the only real option is a custom fitted computerised mosfet that uses microswitches to detect a cycle.

It can be done if you are determined enought but bottom line it's probably more efficient to just get a sidearm for those cqc moments, getting a mosfet that can do this and modifying it would cost about the same :)

I've got a couple reliable sidearms, I'm just not keen on bringing a handgun to a rifle fight. Reckon I'll just try to talk my A-gunner into carrying an MP5 or summat for me.

I have used a number of MGs indoors, and it is definitely less manouvreable than a carbine/PDW/SMG, though not less than anything longer than an AK47.    

 

TBH anything is possible, the question is how flexible are your field rules to having an MG class rifle indoors event on semi-auto.  TBH with speed triggers today, semi might as well be full auto.  

 

Putting a programmable mosfet seems to be the best way to go about creating select fire on the MGs.

I'm not fussed about the bulk of the gun. As long as it chronoes within rifle limits and is actually capable of semi auto, the field doesn't care what it looks like. A pretty fair approach, if you ask me.

 

Blade/double triggers are banned at my local, so absurd semi-spamming is infrequent.

 

I'll give the project some more thought. As it stands right now, I'll likely continue to keep my MGs in reserve as specialty weapons for open terrain fighting.
