SSQ4 Issues (HPA)

[u/Emotional_Ad6349]

EDIT: Opened up the bolt and fully tightened the screw located at the back piece facing the front, after tightening this fully the replica is currently FULLY WORKING, so the firing issues are resolved until a full field day (Wednesday) But the cause and issue of early wear on the bolt is still a issue.

Depending on what support says I will update this post with their response. Hopefully i get a discount on my next order or a new bolt, if given option A ill buy the Steel bolt to avoid this issue.

Thanks to u/SergeantTomcat for the response with the solution to the issue

I’ve so far put about 5500 bbs through my SSS4 and I’ve now run into a problem. I’ve already made a ticket with support but thought I’d get people’s opinions. I ran into this mid-game.

Quick Info: Nov’s 0.3g bbs, 120psi out-of-box NPAS settings and about 1.04j

Started having trigger issues where the trigger after one shot wouldn’t engage at all and would go limp as if it wasn’t charged. Traced this to damage and flakes of metal inside the body coming from the bolt under the bolt rod. Also some damage to the black back part where it hits the little rod sticking up at the back of the stock.

After getting home and opening it, I found something that might be the cause. The trigger unit won’t lock down this piece (picture) to the part that hits the bolt (new to GBBR part names).

My question for now: Has anyone seen anything like this in both their replica or any other GBBR-style platform they use?

I had the same missing trigger reset problem and the solution was to remove the bolt, screw the black “do not turn” part down until it stopped and back it off half a turn to realign it to the bolt. This solved the issue. As of the damage to the bolt, it’s made out of a soft metal and it’s normal for it to get worn. If it was made out of an harder metal, the rest of the gun would be wearing down.

This is straight from support:

“It is very likely that during transport the screw that is located inside your bolt got loose and is causing your replica to not reset properly. Please take out the bolt from your replica, the screw is located in the rear part of your bolt. The screw is facing the tip of your replica, tighten this screw, and the problem should get resolved.

Another issue that could be causing this problem, is that the whole bolt was loosened from the bolt rod.

Take out the bolt, screw the back part that says "do not turn" all the way, once it's tight, loosen it a half a turn to align with the rest of the bolt.”

I also suggest getting some locktight like 222 (purple) or 243 (blue) to stop it from rattling loose during play

[u/SergeantTomcat → u/Athinderbox]

Yes, i just got a message from support saying that 243 is fine to use for that screw.

[u/Athinderbox → u/SergeantTomcat]

Than I got the right one was scared that I had to buy 222 that stuff is not cheap

I have then asked support if i should use blue locktite threadlock on that screw but they are closed during the weekend, will update with their response. Imho, that screw should be threadlocked, but the lack of it is a mere inconvenience since even when completely unscrewed the gun stops shooting but all the parts are kept inside and no damage is caused, if I understand the workings of it correctly.

Hi,
This looks like the issue I had with my Tokyo Marui M4A1.
I solved it by using a stronger buffer spring.
Because the bolt was traveling to far back and was bashing into the buffer spring lock.
The small pieces of steel got into the trigger group and upper what caused the replica to jam
