Fuzzbean Homemade Open-Bolt Pistol

Here's one of the single-shot pistols I just finished building. Just showing the loading and ejection. Sorry, my antique camera doesn't have sound. But you know what "bang" sounds like.

what do u use as the spent case ejector? iam trying to understand the mechanics behind ejecting out the shell b4 loading the next round. From what ive read im thinking thats the bolt has some kind of hooking piece attached that grabs the casing by the rim and during blow back (or by pulling back) it hits a tapered protrusion attached to the inside of the barrel causing it to flip out...am i close?

@adonovan702 There is no extractor hook. Since it is blowback, the blowback pressure keeps the empty shell pressed against the bolt as the bolt moves back. Then there is the tip of the recoil spring guide rod that pokes through a hole on one side of the bolt face when the bolt is all the way back... the edge of the empty case hits that, and the case is flipped out of the gun.

@Fuzzybeanerizer aahhh now, can you instead weld a lil piece of protrusion to like the bottom of the receiver (i think thats what its called, no?) so while its moving back the shell hits the shit and flips out the ejector port ontop??

[Fuzzybeanerizer]

@adonovan702 Yes, you could do that instead. I went with the guide rod tip partly because it was easier for me to drill a hole than to mill a deep slot, and partly because I needed a spring guide rod anyway so no extra parts were needed.

hey, is this leagal to make in the states as long as i dont try to sell it?

[Fuzzybeanerizer]

@soixe1997 Yes, it is legal to make for your own use under federal law. You may have to meet some state requirements for owning pistols in general, however, depending on your state.

@Fuzzybeanerizer you are right now that i think about it, it would be easier to make the guide rod act as ejector...do u know of any web sites i can go to for learning the basics? Im really wanting to make something small but semi, or fully maybe even .22 fully auto but idealy something stronger 32 or maybe even 9mm

[nilsywilsy]

just wondering, how heavy is the bolt itself? did you calculate the weight of it with the whole bolt thrust thing or did you just make something? i've seen a guy who made an open bolt .22lr but his bolt doesnt move back after firing, think it was 160 grams or something.

@Fuzzybeanerizer Yes, Knowledge is power ;) You seem like a smart guy.

[Fuzzybeanerizer]

@redneck500 Well yes... lots of people ask me about "converting" this gun to full auto, but that misses the point completely. I designed it to be hard to convert. To try to convert it would be harder than starting from scratch for me. But the knowledge and experience I gained from building it can't be banned.
