making a magazine

Unread postAuthor: maverik94 » Thu Jun 04, 2009 12:27 pm

Ok, for my single action 4.5 mm rifle, I am considering making a magazine so all I have to do is pump, shoot, pump, shoot, etc. I am thinking of using a weak spring to push bbs down a tube the same size as the barrel. However, I see 2 problems.
1) more than one bb may shoot every shot
2) air will also go up the tube as well as down the barrel
Does anyone have any ideas on building a magazine like this?

If its single action you could have a reload system were a sleeving pipe shuts off the magazine so only 1 bb or pellet would go in and there would be no dead space.

It pains me to see so many people struggle with magazines.

My solution; Never, EVER reinvent the wheel. Use existing magazines.

Don't waste time and energy (not to mention money) on trying to create something that you know is going to be a colossal challenge. Get an airgun magazine from Wal-Mart, and create a slot for it out of Bondo (if possible, make a molded copy of the original reciever). My favorite airsoft mag design comes from a shitty softair spring pistol. It uses a mag with a small slit runnint along the top, with the hole for the BB in the front face of the mag. A tang on the bottom of the piston slides through the slit and pushes a BB up a ramp and into battery. If only they made STANAG-type mags like that... Then again, tangs don't like rotating bolts...

well, #1, I want to make it myself, and #2, I'm making a 4.5mm air rifle, not a airsoft gun.

i agree with SEAKING9006's first 2 sentences (he's on his own with the rest.)
don't reinvent the wheel and most of all don't hurt your brain over it.

qwerty also has a great point. connect a sleeve mech to the pump action mech. every time u pump it will load the breach then seal it back up again.
i'll draw it out next time i log on.

well, that was kinda the idea I had...but i didn't think of connecting it to the pump. Also, my gun is a lever operated single action pistol...so it way be kinda harder, but well see.

the sleeve thing has been done a few times before. so, as i said, don't reinvent the wheel. i make it a point not to contradict myself. so far i'm still doing a great job. reread my last post then you'll understand. i only agreed with the first 2 sentences.

and thanks for drawing it out. u saved me the trouble.
