ICS GARAND full auto

[Retrogrouch]

Hi out there, Has anybody found a solution to the ICS garand going full auto? It seems like an somewhat common problem with the weapon, but I have yet to find a good solution.

Thx for reading

Had this happen with mine. Now it might be a slightly different problem as mine would go full auto as soon as you plugged the battery in. Turned out to be the Mosfit was baked. Took it out as it is a plug and play style, works fine know. Not sure the reason for a Mosfit on a semi only gun?

Make & break of the trigger contacts when it arcs. Full auto easier on contacts

I'm pretty sure the ICS Garand uses a V7 gearbox. V7 gearbox cutoff levers suck, replace that.

As for a plug and play MOSFET causing full auto I don't understand how that would even work. Plug and play MOSFETs are useless.

semi auto is the hardest on a gearbox. Full auto if set up correctly really only puts strain on the gearset and piston when the gears start and when they hit the piston to grab it.

Semi auto is always starting from a dead stop to slam into the piston and then dead stop again as it finishes the cycle. The trigger contacts arc every time you pull the trigger, whereas in full auto the block arcs once as the block comes close to the contacts, but then it stays pushed in rather than ejected by the cutoff lever.

semi auto is also hardest on the battery as the startup to get the gears moving requires more current than it does to keep it constantly moving, even with the slowdown when the gears pickup the piston.

Lol I'm pretty sure he asked because he thinks the only point of a MOSFET is to have a burst function... So pointless on semi only.

ah yeah, well burst controllers are garbage either way. :P

It's not a V7. More like a variant of the G&G/CA M14 gearbox. Gears, AV Latch, piston, cylinder are all standard. Cut off lever is a V2 type. There is no selector plate or any way to select from semi to full. The trigger shuttle seems a bit short where it would engage the cutoff lever. I'm thinking that's where the issue is.

Have one on the bench currently, so I know this. I can take pics if people want. Gearbox is also made to go into an future M14 model. There's a spot on the right side for a selector to be attached.

Cool, good to know. I just wish the G&G/CA M14 design could use a V2 cutoff... Or at least had interchangeable cutoff levers...

[lurkingknight]

the g&g m14 gearbox is actually pretty good, at the very least g&g has good factory support for their weird parts, unlike ares.

Just to clear up what I was saying Pesto. The Mosfet in the ICS Garand is plugged in line so it can be removed. I didn't add a plug and play moset, sorry just didn't explain that very well. Now what happened was one of the wires pulled out causing a short so that as soon as you plugged a battery in it would fire full auto, you did not even have to touch the trigger. I did not know that the mosfet is actually more important for semi fire then full auto if I understand that right.

The G&G cutoff lever design is meant to do dual duty as a decocker/spring release as well.

^that would be the AR latch not the cut off lever.

[Darklen]

The G&G selector actually does both. Turn the selector far enough in "auto" and it's supposed to trigger the AV latch. It also moves the cutoff lever out of the way for auto. There is no selector plate in a G&G M14.

Well that was never a feature in the one i owned.
