G&P M4 acting like it's on safe when switched to auto.

ahh yeah - that kinda makes some sense - PDW = locked to semi

well nothing a little file in top right corner didn't fix

I hate these toy gun stuff - but after overcoming problem after problem after problem and stuff "starting" to work it gets rewarding

(tell me that after I thrown all dummy's out of pram and bits of guns down the garden sitting in a heap cursing & totally exhausted from frustration)

anyway - enough about me & my odd problems...

Hopefully OP has some idea of what to look for and see if he can fix/overcome this if all else works ok

I'm off out to the shops just now to get a long handled screwdriver so I can get the gearbox out of the receiver and some expoxy to add some material to the selector plate. Will report back and let you know how I get on gents, thanks for the help so far !

 
Sorry for the delay in reporting back - motor plate screw stripped and couldn't get it out. Had the gun apart and I think the problem lies with the selector plate being incompatible. I think its an SHS re-inforced type, and the extra meat might be causing too much resistance? There were shavings of plastic coming out of the grooves that hold the selector plate on.

I put the gearbox back in the lower receiver without the body pins to hold it in place, and the selector would move the selector place as it should about 75 percent of the time. Put the middle body pin in and if I pressed the front of the gearboxs downwards, it would usually move as it should. Rear body pin goes in and it doesnt go back far enough...

Anyway I've just ordered a G&P low resistance polymide selector plate from firesupport so will see how I get on with that!

On a side not, anyone know where I can get replacement motorplate screws? Saw on a yank forum about them being M3 machine screws , does anyone have any experience with that being true?

 
motor plate bolts are M3 - if they are bolts

can be self tapping screw type but most decent brands use bolts and M3 is loads of places around gearbox etc....

Gearbox bolts - M3 from small 6mm on top of v2 x 4 or 5 to the main bolts - M3 again up to 18mm long

(20mm or more is v3 motor cage bolts to gearbox)

Pistol grip to gearbox - pretty sure these are also M3's too pan head or flange type to be precise

motor plate - yup should be M3 bolts unless they are actual screws

 
Cheers duck they are actually bolts, was repeating the slosh I'd read from the otherside of the pond lol.

 
G&P selector installed , gun working perfectly now. Thanks for the help gents.

SHS reinforced selector plate not compatible in the slightest , you can see that just by comparing the two - bad job tech lol.

 
ahhh - the classic "TM compatible" minefield of quality crap aftermarket parts

No say SHS - G&P is not TM compatible - the fight breaks out, chairs tables glass everywhere....

OK - G&P are not SHS compatible....

NO - SHS are not G&P compatible.....

More fists start flying.......

Ohhh heck I'm out of here, call the ol' bill coz this is getting ugly now....

Glad you got it sorted sir :)

Interesting findings coz sure I got a box somewhere which "might" be G&P

so will check or look forward to any WTF issues if I start rebuilding it and using bits n bobs that don't play ball etc....

yeah - some of this crap makes the "joy" of closing your first gearbox up - look like playing with duplo

(don't remember any major modding required for duplo - ok death star or millennium falcon is an awesome build but duplo is more my level)
