GBBR M4/M16 Magazines question
 

I am curious about why a gas tank has to be built-in to a GBBR M4 magazine?

Would it be more flexible if a gas tank was separated from an actual magazine, so a GBBR M4 can use any AEG M4 magazines? (i.e. EMAG, PMAG..etc)

For example a pistol grip or a stock would be perfect places for housing a gas tank. I would see this as an attractive feature for any potential GBBR buyers.

I wonder why GBBR magazines are designed the way they are?

IF you're talking about making the stock or the grip like a GBB mag... it's because with every mag change of BB's you've got fresh gas... You'd have to turn your gun over and re-fill it with every mag change instead of having pre-filled magazines.

If you're talking about an external line... They do exist, but they were for the most part phased out by AEG's waaaay back.

if the gas source is gun bourne instead of mag bourne, the number of fhots is limited to the guns capacity, but in the mag you can fire as many shots as you have mags

Would the issue of capacity limitation be overcome by a larger gas tank housed in a M4 stock?

Take a gander at Daytona Gun, or Classic airsoft. They have the air supply separate from the gun.

To answer your question, there's no room in the stock, nor the pistol grip to hold enough gas i would think.

no, it would be MORE shots, but still limited to the gas capacity, it can never be "solved"

Unless you can somehow fit 2000 shots worth of propellant into the stock...

Nope.

Well words have that Justin of Daytonagun is working on making a F2000 from G2010 base. Folks at the CA forum said that there might be able to allocate enough space maybe for a 9oz tank. (that's approx 400 shots) Although I doubt it as regulator aint small.

That would be feasible because of the size of F2000 stock. For M4 family, we need a creative solution for housing an 9oz tank or smaller. External PEQ box, specially designed foregrip or even unique shape gas tanks for fitting into rail systems/handguards.

SRC was working on a GBBR platform back in 2007, and from the pictures I have, it had 12g CO2 cylinders in the buffer tube....

OR just use gas in mag systems or daytona gun "classic" systems and not try and reinvent the wheel.

if it ain't broke........

in the magwell it was crap....beyond that..

M4 simply dont have space, even if you use a 12" M203 and have it all the way maybe you can manage a 9oz...

This is actually a very nice idea. The buffer tube should be big enough. If this is possible, then GBBR could be able to utilize AEG mags.

but co2 in buffer tube = no recoil...since the bolt would have nowhere to move.... unless they frankenstein a PDW bolt in it... :S

G&P released few years back a drop-in CO2 mechbox (co2 in the grip)...but it could only shoot semi...
