TM No Hop Up=Roll out

[MatthewRyan]

Hello everyone I have a Tokyo Marui PX4

In a nut shell No Hop Up = BB rolling out

I feel like the Hop Up is also working as a ball dentent
Even when I pull the slide back to chamber a round sometimes it just pushes it right out the barrel

Adding hop up isnt a big deal ..only need to turn it 1/4 of the way to fix it
but

Anyways its not a major issue but is there some way to fix this minor inconvenience has anyone else had this issue on any other gbb?

Thank you

Is this a Hop Up issue or a bucking issue ?

Try turning your hop up back on if its all the way off then yes your bbs will roll right out.

Don't keep your PX4 in a nutshell.

^ i lol at that

I also recommend not keeping your PX4 in a nutshell. It's dry in there, can dry out the seals.

If you have no hopup on, yes you might have BB's being pushed out. That's just a fact.

Use heavier bbs then youll need to use some hop up so the fly good.
What weighg of bbs ard u usein that u need ths hop up all the way off...

Im using .20s. I'd just figure that the gun can shoot without hop

It can, but it will have crap range. Why would you not want the longest, flattest trajectory you can get?

Also you should be using at least 0.25's in GBB's if possible.

[MatthewRyan]

Obviously .. I just though that the gun can shoot and chamber a bb without having any roll outs .

Note taken on the .25s I just play indoors for now but I will try a heavier bb

Even with 20 you will need some hop up to have a good long flight path. If the gun is newer it may have over hop at first till the rubber gets worked in. I figure if its a tm the fps is kinda low so 25 is prolly perfect i run 30 in my gbb but they shoot 400fps or so

[Styrak]

Jesus what do you have that shoots 400? CO2 NBB pistols?

[hattrick]

You can change brand of bb. IIRC brands can vary from 5.95mm to 6.05mm. Find said 6.05ers and maybe they'll sit a little more snug.

Kj m9 vertec 385fps green/propane and a gemtec oasis 410fps nbb propane.
Snipers need heafty pistols for those folks who get within 120 feet ghat its nlt safe to shoot em with the 515fps bolt action lol

[Styrak]

That's a strangely high FPS for a propane mag in a KJ M9.

Try swapping the hop up rubber to a stickier one if you want to shoot with it off... but again, I don't know why you'd want to shoot with it off. :P

Otherwise, it's known fact for this to happen with your hop up turned off.
