yea boi, this was a project my buddy had me draw up and build for him, a blow back assisted bolt action pump.

took some time cause my dremel went wacko and almost cought fire.

enough talk here it is.

It's a bolt action....NOT A PUMP. Like comparing a bolt-action rifle to a pump shotgun.

Otherwise it's good.

That looks pretty neat. but im confused. Is it pump style action (shoot, cock, shoot) or not?

so when you rotate the bolt, you catch the hammer because a u is carved out of the hammer up to the normal hole (allowing it to catch in the cocking direction, but not the firing direction), then when you pull it back the hammer catches the sear, you push the bolt forward to seal the chamber and then rotate it to put it into a locked resting position. you fire and the hammer comes back. good design but the hammer will rotate and will unalign with the sear and wont catch. im 90% sure that is how you made this bolt action, but if it is bolt action, then it wouldnt require you to catch the hammer, because the valve will cuase enough blowback to reengage the hammer. that means that the bolt is only moving to load a ball, not to recock the marker... yes, i did just figure that out while typing and was to lazy to go back. you should fiddle with a reg so that the gun gets enough air to fire a ball at normal velocity but will not recock, and wont sputter so you can use the method i described.

thats close.. it has the same princaples but i did it different.. ill draw it up on paint real quick



before you say anything.. i know i cant draw in paint worth a crap :-D

what i did was....

took the pin out of the bolt, cut it down then jb welded it to the striker, cut 2 notches into the bolt, one for pushing back on the striker, and the other to let the striker move freely down the body hit the striker then push back, its still a semi auto shot, but you have to cock back the bolt to get it to load the ball, i tryed to make it a full blown pump but it wouldnt stop recocking lol dropped the pressure down to about 300 psi and it kept trying to recock, and was having terrible drop off. i consulted my buddy on it to see if he wanted me to keep working on that but he didnt want to wait anylonger :tongue:. so i abandoned that idea and made it like this. if he had wanted me to continue with it i would have but it would ovibously take some modifying to the body and striker. tryed the both but it still recocked :jawdrop:. im putting a modified gas thru on it and cutting the head off the bolt and replacing that with a dice hehe liked the one on my promaster and asked if i could do it to this. thats basicly it. the only drawings i did on this are the ones i just made today hehehe, gots it all figured out in my head.

the three of us were on the phone when he gassed it up. It really does work even though it sounded 'light'...said he was almost outta air so that would be the reason.
and it operates like a normal bolt-action rifle...just that the bolt's on the left side instead of the right. Now...something that I just thought of would be to use a QLoader, side-mount the feed neck to zero-out the profile and it'd be done.

Couldn't you just as well turn it to stock class tubing? Lol, save a lot of money, and won't be half as useless.
