jg g3 sg1 accuracy problem

[drifterex]

hi. i have a jg sg1 for bout a year now and since i got it i've had serious hassle with accuracy. from a distance of approx 25 feet it cant hit a coke can. now i may not be a marksman but none of my other guns are that inconsistent. using iron sights you have aim way above what you firing at and the same with a scope, with the crosshair adjusted as far up as it will go. i have upgraded the barrel to a promeheus, classic army metal hop unit and new hop up bucking but made no difference. i just really like the psg / sg1 look so was goin to buy a classic army sg1 as the metal body will reduce barrel flex, or maybe a psg1 - but have heard mixed reviews on psg's - or can i expect the same sort of performance. sorry bit of a long winded question.

mark.

Re: jg g3 sg1 accuracy problem

At first glance, it sounds like the inner barrel is slightly bent.

Do you, or have you, stored it with ANY weight on the barrel (ie on wall hangers or leaning against the wall)?

In my experience, the classic army hop up unit is what you are struggling with. Try going back to the plastic TM hop unit.

I replaced my TM body with a CA metal body, but didn't get a hop unit, and the whole thing double fed, fit very tightly and BB's dribbled out to about 10 foot at most.
Got a metal hop up and it worked fine, which told me the recievers need the same brand hop up unit to match.

If you still have the Plastic JG one i'd say use that, you don't NEED a metal hop unit, if anything the seal is better with plastic air nozzle on plastic hop unit. The only reason that metal ones are around is because the M4 hop units can break if i can remember i don't know of any hop unit that has broken through wear and tear for the G3.

Classic army G3s are good but mixing them with TM parts or vice versa can cause issues.

Did you have the problem before you fitted the new parts?

Re: jg g3 sg1 accuracy problem

So even with a large amount of hop on the BBs are still dropping short? You are putting hop on?

Re: jg g3 sg1 accuracy problem

this is interesting.

i just bought a JG G3 T3. it fires really low.

first i thought the barrel section had been twisted from the body of the gun by being dropped or something. now i think that they might just suffer from a design flaw due to the plastic joint on the front section of the gun being to weak.

hop up helps, but for my gun this starts to cause blocking issues.

the simple way around this i've found, is to switch the rear open sight to 3 (just to give you a higher solid line, not to use the pin-hole on it) and then place the whole front open sight circular section on top of the line created by the rear sight. this should make the open sights usable.

i also have a scope and had the same problems.

what i have done is place a shaped piece of metal (only on the rear) between the actual body of the scope and the small primary mounts (using tape to protect the scope body).

the sight is now jacked up at the rear, enabling the zeroing of the scope and barely using any hop.

i now have the scope zeroed to 60 feet where i can put down a fairly decent percentage of spread within a 20cm target.

i have found the hop to be unstable though. i seem to have to tweak it every time i put a new mag in (500 rnds).

Re: jg g3 sg1 accuracy problem

i'll try and reply to each query here, so sorry if i miss someone. the rifle has been firing like this since i got it brand new. the reason i got the upgrades was to try and rectify the problem. if i use hop up i nearly have to turn it on full to be on target, but this can't be right for such a close range shot, can it?
if i buy the classic army i wont be using any of the parts i purchased for the jg, moreso just wat to know if it's a good accurate weapon. or would a psg1 be the way to go as that is what i actually want, but have heard they're quite poor. does anyone have any first hand experience with a psg1, and if so how does the accuracy rate?

oh and blix i did the same thing on iron sights. someone had recommended that i put something on the back scope mount but i never did it. just bought my well .338 instead.

is that an r33 gtr in your sig fizzy?

Re: jg g3 sg1 accuracy problem

i've only had a AEG for a few days drifterex, but the way i understand hop-up is that the effect of the back-spin will increase in relation to the distance.

so increasing your hop and then only firing 25 feet, might not be a good way of assessing the effect your hop adjustment is having.

Re: jg g3 sg1 accuracy problem

oh i understand that, i was adjusting the hop up in very small increments to see what effect it would have. and it does certainly help. i was just expecting to aim down the sights as with any other aeg i've owned. like you said it does sound as if there is a design flaw in them.

It's a GTST

When you replaed the hop bucking, did you replace the nub as well? If not, that may be your issue. It could be too short/soft and isn't applying enough hop

Re: jg g3 sg1 accuracy problem

nice. any pics of your skyline up on here. i have an r32 gtst.

anyway back on topic, yeah the bucking kit came with a new nub so used that. but the problem was there before the upgrade parts were installed, which was the reason i got upgrade parts in the first place.
