Blowback vs. Blowforward

[Lord Delta]

While cleaning my marker I actually took the time to examine it closely to figure out exactly how it works. My question is how does a blowback differe from a blowforward? If you know of a website that has a diagram of a blowforward just send me that and I can figure it out from that. THANKS

The automag website has a diagram of how its blow forward system works.

[elTwitcho]

In a mag, air is stored behing the bolt in a valve. When the sear is released, this air pushes the bolt forward. The air goes through the bolt and there is nothing left to keep it forward. Small springs bush the bolt asembly back to it's start positon. The sear locks it there and the valve fills with air again. At least that's the general gist of it, it's slightly more complicated though

in a more simplicstic approach.. the spring is on the opposite side of the bolt/hammer. The spring resets the action instead of the air in a blow-back.

You said that is how it works on an automag (mag) Is it different for an autococker (I realize they are quite different markers) Or is an autococker not a blowforward? What markers are not blowbacks? Are electros blowforwards or just called electros?

a cocker is not a blowforward or blowback. it is a pneumatically controled closed bolt.

the only blow forward I know of is the mag. piranas, spyders, F4s, most stacked tube guns are blowbacks.

Ok, What does that mean 'pneumatically controled closed bolt'?

[PiRaNhA69]

dont forget that pumps are really closed bolts.

anyone got the link to the mag site?

Actually, it uses springs and therefore isnt a pnuematically controled ram/bolt like an angel bushy or impulse. It's an auotococker, and just that.

The way it works, is like this

-Bolt is closed with a ball in the chamber
-Hammer goes into poppet valve opening it and firing a ball
-Back block cycles, pulling the hammer back into a cocked position. It locks with the sear. The bolt is also pushed backwards so a ball can drop into the breach.
-Back block moves forward closing the breach by moving the bolt forwards. However, the hammer remains cocked as it's attached to the sear.

And there it is

www.airgun.com something like that.

actually

is a thousand times better

and exactly how does the bolt cylce??? hmmm? through a pnuemactic ram! that is controled by a pnuematic 4-way valve! do your homework, before you make yourself look dumb! I did not say it was electro-pnuematic, just that is was pneumatically controled, which it is! yes the hammer is fired though a spring, but the bolt is not.

lol dude, chill...

lol idiot. I stand by my original post, if the hammer is moved with a spring, it isnt full pnuematic. And yes, seriously chill out, take a pill, go for a walk, wack off, do whatever, but making "hahaha, I'm better than you so do your homework" posts isnt a quick way to make friends

Here's the easiest way to think of an autococker. An autococker is simply a pump gun that has an extra mechanism to recock the action instead if a pump arm. Thats it, thats all.

[xen_100]

but, giving incorrect information is not the way to conduct yourself either. saying that an autococker is not a pneumatically CONTROLED gun is tottaly wrong. weather or not the hammer is force forward with a spring or not. the hammer cant be put into the cocked position without the aid of the pnuematcis.

[elTwitcho]

So since gas pushes a blowbacks hammer into the cocked position, it's fully pnuematic now? And yeah you can cock the marker without gas. Take your tank off (now there's no gas) grab the back block, pull it back, then forward. Wow, it's cocked.

As for pnuematically controled, you pull the trigger, what moves the hammer forward? A spring. What prevents the hammer from moving forward when it's cocked? A sear. Neither of those are pnuematic components

[xen_100]

ok, with that arguement then an angel, bushy, imp, et all are not pnuematically controled then either. cause the trigger, silenoid, wiring, and control board or not pnuematic parts either. if you want to get into sematics I can do that too.

I would love to hear how you would define the word "pneumatic control" cause you dont seem to know.
