rear sight aperature G&P M4

frag7 · October 18th, 2005, 22:30

Hi

I just bought a used G&P M4 full stock and I have a pb aiming with it : it shoot too much to the left and I have to set the rear sight aperature full right to shoot what I aimed : it sucks ...

Any idea how to fix that ?

C'mon Docs !

clean your barrel and hop-up

I did it :neutral:
As it's a metal can I use the same tools ans technics as a real one (metal brush) ?

no that's the best way to ruin your gun. if you cleaned it with a metal bore brush and rod you probably scored you barrel (ie. TOAST!!!) and either ripped the shit out of your hop bucking or at the very least baddly scored it also. not a smart move. use a soft plastic bristle brush like what comes in some airgun (pellet gun) cleaning kits or use one like the marui cleaning rod (see if you can borrow one from someone if you don't have one yourself). you are going to have to tear the gun down to see if you did serious damage. if you don't know how take it to someone who does.

ok, thanks for the advice

It shoot good with the aimpoint so it should be enough for this we, but it's disturbing...you seriously think a cleanup will help ? With rear sight in the middle I shoot almost a meter to the left at 15 m...that's a lot 8O

you bet. cleaning the barrel and hop-up makes a huge difference. and 3 feet of drift at 60+ feet is not unheard-of. not fantastic accuracy, but not unheard-of. my g&p spr/a can hit a person at 200 feet with no problem. but it's shooting 435 fps with .25g bb's. when it needs a cleaning i can tell as targets get hard to hit at ranges that normally wouldn't be a problem. remember an airsoft gun is nowhere as accurate as the real steel. little things like wind cause big accuracy problems over short distances.

ok ! do i need to take it down to clean the hopup , or just all the way down the barrel with a soft brush is enough ? Is Wd40 ok for gearbox and barrel or gun oil is better?

WD-40 will eat the hopup right out of the holder. Use a silicone oil instead.
