G&P m4a1 instruction manuel
 

long time ago i found the manuels, but since i formated my computer and forgot to save them i lost them. i been searching for houres with out even coming close to finding it. looks like G&P instructions are hard to find :( if any one can help me find the manuels i would appreciate it.

some G&P guns just don't HAVE manuals, i emailed them and they said they were working on the G&P 249 manuals lol
Their M4's break down the exact same as all other M4's, shouldn't need a manual anyway, i mean it only goes back together one way lol

k, well i checked a TM m4a1 manuel and some stuff that moves doesnt move on mine. Cause i need to know basic maintenance for my m4 and watch does each moving part affect the AEG. like i know the fake ejection shell thing is for the hop up. but i dont know what does the knob to reload the AEG if it was a real gun does. And for under the grip witch side i turn to turn on or of the motor "i mean by having the motor tuch the bushing.

the forward assist does nothing, just like it does on every other M4
the motor adjustment is clockwise to move it towards the gears, just like it is in every other AEG
if it's straight from G&P and NOT a WGC custom, you REALLY need to open it up and shim the gears before you do any heavy playing with it, needs a lot of shims.

the gear box has be upgraded from the previous owner. My question is how do i uncompress the spring if i can only shoot auto. Cause the guy that owned it said not to shoot semi cause it can brakes a certain spring, that happened to him befor.

I've never heard of that ever happening
It could always be that the spring he had was simply defective, it does happen.
If you really want to know, theres 2 ways to uncompress that spring, #1 you take out the motor and hit the anti-reversal latch (complicated and time consuming)
#2 just tap your trigger VERY quickly, you'll hear the piston wind back, wind a bit more, and then WAP, and its uncompressed. Thats what we have to do on M249s (easy, takes 5 seconds)

Now the only issue I've ever heard of on semi auto (which is common to most airsoft guns) is if you release the trigger before its done cycling in semi-auto, the trigger jams. Usually you can flip it to full auto and it will unjam the trigger. On a GR25 its a bit more complicated lol
Not sure of what's actually going on, but when you fire semi auto don't release the trigger until the cycle is complete.

damn didnt know there that kind of problem... i might have to make a electronic device to control the firing modes... thats if i can get my hands on a few airsoft pieces and make test to see if it possible :) , and i would add a decompressing spring mode on it :D .

theres really no point, it'll take WAY more effort to install the system than it would be worth, and your spring will wear down no matter what you do because you have to compress it to get it into the mechbox, it'll just wear down slower if you leave it 'uncompressed'

k, well i was going to add other feature to it like, selecting ROF, selector setting like how many shoots per burst and all so make it so you dont have to keep the finger on the triger till it fires in semi auto.

the semi auto jamming only occurs if you pull the trigger again before its done firing, its really nothing to worry about.
most real guns don't have ROF selectors, just bring your ROF to where you want it (by changing batteries, different gears, spring, etc)
as for a burst trigger group, people have tried, im not saying you shouldnt, but it's difficult.
