duster as in hfc134a gas, lower pressure than propane thats typically used here in N. America, but was what the gun is designed for in Japan...The plastic slide and light spring of the stock gun works with the light pressure gas. The need for higher power gas is because of the lack of need to comply with the power rule of Japan, and the fact that people like metal slide upgrade for more kick.

Oh, ok! That makes sense.

Thanks.

Alright, the adapter arrived today so I went to pick up some propane and now it works flawlessly. There is a lot of spread in the shots though; they wander around a lot. Is this common for pistols?

Also, the propane slowly leaks out of the mag..I can hear it escaping. The valve on the mag is threaded, but it's tightened all the way. Any ideas how to remedy this?

Is it a TM mag? If it leaks on the bottom, tighten the bottom screw. Should be a phllips head. As for lots of spread in shots? BBs spread on target? If so, use .25g or heavier, and then check your hopup.

[RacingManiac]

Its common for bad shooter... Not entirely serious, but pistol demends much more on the fundamentals being applied properly. And compare to AEGs, GBB with its moving part is more of a challenge to master.

Is this a new gun? Used? Marui mag usually are pretty easy for upkeep. If its hissing gas, take the mag apart(fill valve, release valve, base plate), lube all the rubber seal with silicone oil and put it back together usually is enough for it to seal properly again.

I was using .25g BBs. How do I adjust hopup on a pistol? I have tightened the screw, but maybe RacingManiac's suggestion will fix it.

Hey now! I'm a pretty good shot with a real handgun, actually much better than I am with this lol. :P

I'll take it apart and have a look-see. Thanks for the suggestion.

[airplaneman]

Alrighty, that fixed it! Thanks guys.

Now for that hop-up adjustment, how do I do it? And the biggest problem is left/right accuracy. Height-wise it's fairly good, and I'll account the misses as an error in my aiming, but sometimes the bb will fly a foot to the left or right of a target at 20ft, and I know my aim isn't that bad :P.

If you strip the slide, there should be a little wheel that says "Hop" around the chamber area behind the recoil spring guide. Fully towards the tip is minimum hop, and fully towards the rear is max hop.

I'd clean the inner barrel, make sure no oil is in there, clean the hop-up rubber also to be free of oil. Make sure the hop-up screws are tight also. A stock Hi-Capa should be fairly accurate....if not a bit under power. Around that range I can shoot with minimum hop and the shot should be fairly level...

As mentioned earlier, height isn't my issue, it's the side to side accuracy. I'll try cleaning the barrel and seeing if that helps. I can literally see the BBs curve in the air..maybe its just the wind catching them or something?

[kingbudha]

hopup doesnt affect side to side just up and down, it is probably the wind.

I'll pick up that adapter and hopefully it'll start working.

Thanks! And you'll hear from me in a few days if it didn't fix my issue :P

Where did you get this "silicone lube" from? I hope it's not the Canadian Tire stuff.

Also, I hope you flushed your magazines of the butane ASAP. Butane will rot your seals.

Butane is NOT "Red Gas". In fact, it's quite the opposite.

"Red Gas" is CO2.

Yes, butane is even lower than duster.

Let me put it this way: if you wanted to blow dust off your computer components, the last thing you're gonna grab to blow gas out is a Bic lighter... the pressure that comes out of that is so mediocre, I could blow harder with a straw.

Not at 20 feet range... you wouldn't see a 1 foot deviation unless you're shooting during a hurricane... Even with a dirty barrel, I can't imagine deviation like that from such a short distance. The only thing I can think of is shooter error.

I got the silicone lube from an airsoft supply store, don't worry . If by flushed the mag you mean emptied it and re-filled with propane, then yeah, I did that. Butane never stayed in the mag very long.

Maybe it wasn't 1 foot, but it had to be at least 6". Could have been error on my part. I only shot 4-5 mags worth of BBs, so I'll see how it performs in the future.


Thanks for all your help guys, really. I'm glad to have this working properly.

If your shot ends up 6" from the spot you originally wanted to hit, its more than likely user error. Like Brian said, at a distance of 20 feet you shouldn't find much deviation at all.
