Help. KWA Mac 11

heyds · March 26th, 2010, 18:48

I know I created a thread similar to this in another part of the forum, but I never really got my question answered, and the thread is pretty much dead. Plus my problem is seemingly getting worse and worse as the days pass...

So here it goes...

My KWA Mac 11 shot very well after I first got it, but lately (about 3 weeks after I first shot it maybe more or less) the bbs are getting jammed in the hopup rubber before entering the barrel. The first few shots of the clip will be fine, but all of a sudden one will get lodged in between the rubber. When I shoot another after that the bb that was lodged gets pushed forward and the bb I just shot gets lodged. Now my question that wasn't answered (although I assumed it was a bb problem) was what is causing this. I am using generic bio bbs, which I plan on changing soon, but I was just wondering if that was the only possible problem. Could it be a loss of pressure? Is there a problem with my hopup? Is it a lubing issue? Any information would be extremly helpful, and is greatly appreciated.

Regards,
Heyds

Shitty bb's are probably getting jammed in the hopup since they have a low consistency from bb to bb and probably seam lines+other flaws. Try switching to bastards that should solve your problem.

I have 2 of these, and they are very finicky on what bb's to use. I've used KSC, Madbull, and Metal Tech. MadBull's were crap, MT's were not too bad, and the KSC were great. Clean your mags and bolt etc and it will treat you good.

Have not had the opportunity to use bastards but I have yet to hear anything bad about them.

Fuck it use BB Bastards, they work flawlessly in all my guns, plus your supporting a fellow Canadian airsofter.

The last two guns I put new inner barrels into had been used with around 2,000 cybergun bio bbs (arctic white and the green shit) so I put them into the persons case to return them. After showing them the gun and having them test fire it I pulled out the old barrel and cleaned it right in front of them. Both guys will not use any bios again cuz they seen the residue and know that 6.03mm leaves no room for error.

Throw them out or pick up a grenade to use them in, pick up some nice quality BB's
(BB Bastard)

Give your barrel a good clean, enjoy your Bastards

Ok, thanks all. Based on all this feedback, it relieves me to know it is most likely a bb problem.

I will pick up some better ones as soon as I can.

Regards,
Heyds

We told you stop using bio cyber shit bbs and you haven't tried bastards yet?
