King Arms M203 Round Help needed

Jbone 11 11 · February 11th, 2010, 15:14

Just got a set of king Arms Xm 1060 Grenades and like the tool that I am, I let curiosity get the better of me and un-screwed the shell... needless to say the bearings fell out and now I see on King Arms site that a Re-load tool is needed to get the bearings back in!

What I want to know is, if there is any work around so I don't need to order said Re-load tool. I saw a post for Classic army shells( http://www.airsoftcanada.com/showthr...ht=m203+repair) where that person did the same as me. Are they similar at all? Could I use the solution in that post with my KA Rounds?

Thanks,
J

Yes that will work. That is how most/all M203 shells are built.

you don't need a tool. just dab a bit of grease on the bearings and they'll stay put.

+1 on the grease, that's how I do it
Also, they sell rebuild kits (FINALLY), incase you lost any pieces

The grease worked a charm! Thanks for the tip!!

BTW... is it normal for the Inner valve (not sure what to call it.... its the bit the bearings sit in with the bigger O-ring around it that plugs into the gas chamber) to un-sit itself, pinching the O-ring after every shot? Im having to Un-screw the shells and re-set the Inner Valve manually after every shot, or I can't fill it back up.
I've put a bit of grease on the o-ring in one of them in hopes that it'll stop the O-ring from pinching when it tries to sit back in the chamber. I got a game tomorrow, so fingers crossed!

they are finnicky, i have one grenade that blows the Oring into the chamber each time I use it, so :S

Thanks for all the info! One more question: The 203 launcher I have is a made-in-China cheapo I got off of Ebaybanned; worked fine with a short (also made in china) shell I got with it, but with the King Arms XM's I've had to stick a bit of tape on the percussion cap so the Launchers firing pin can push it in... otherwise its too short and wont set off the round.

Wondering if this is a common thing with King Arms shells, the XM design in particular, or my cheapo launcher. I suspect the later, but Im not to knowledgeable about all the different manufactures, hence the question.

Thanks again!

my launcher has a screw in the firing pin that can adjust for length of the push needed, so Id assume its a problem with your launcher just not pushing far enough

coach · March 3rd, 2010, 09:24

different launchers are made for different shells so the firing pin isn't always going to be long enough.

if memory serves, the KA valves require a longer firing pin than a madbull. (needs to be pushed in further)

you could make some metal slugs about 5mm and glue/jbweld it to the back of the valve. would be more consistent than a wad of tape.
