CA mp5 sd

[Jimmypie]

Ok here it is, shoots fine on semi, but when switching to full auto every 4th-5th shot either hits the muzzle/suppressor or flies off in a random 45 degree direction, ive checked the baffles and hop ,now im stuck.

Does it still do this when the silencer is off?

[Jimmypie]

no because there is no silencer to hit? this is the SD version its part of the rifle.

[BakaBox]

But you can still remove it.

[Jimmypie]

yes, its been removed to inspect the baffles, these were removed and the rifle still fired the same but not as bad, could the inner barrel be moving around when its firing on full auto?

[brian222]

That's wierd, the silencer can screw off on my ICS MP5.

I assumed it was that way on the CA MP5's also.

[Jimmypie]

the silencer does com off, but the problem is when its on, sorry if im not making sense but im doing this for a mate , trying to guide him through it on the phone, i have a basic knowledge of the mp5 series but am not 100%. It seems that when it is fired on full auto some sort of turbulence is building in the silencer and throwing the bbs out of sync.

Check that the hop is set right.

Is the inner barrel clean? I mean something so small could give you huge problems. Swab the inner barrel with silicon and try again. (remember the first 20-30 shots after swabbing the inner barrel will be crazy shot!)

[Jimmypie]

it seems to be a regular fault, every 4-5 bbs, ill wait until i can get my hands on it and open that sucker up , hopefully then ill be able to make a better evaluation.cheers anyway guys.
