If you haven't seen these yet, the concept started as a "for $10 and 3 hours of time, make a gun in your garage with simple tools then trade it into one of the local gun buy back programs" This is to prove many points, the buy backs don't get guns off the street, its a waste of public resources, they can't stop people from owning guns, and you CAN make a gun that works. Even with simple tools. So, I didn't buy his plans nor did I research how he did it anything beyond my head turning after seeing a video. The result is a poorly planned, crudely executed version of Marks design. Yes I have a mill, I have a lathe, but I didn't use them. The most expensive tool I used was a $100 drill press and that could have been done just as well with a hand drill. The majority of the work was done with Harbor Freight right angle grinders, a hacksaw and files. Hence the crude results. Rough Cuts Fitting the “Bolt” or center piece of the “slide” Drilled the “Bolt” not to match it up to the slide slabs Gutting the “Bolt” for springs Guide pins for the springs Slide fitted Need a recess for the rim A little off center, but that’s how it goes with crude tooling sometimes… Firing pin hole Barrel block rough cut Cutting slots for the “frame” Slots done, time to drill it Soldered in a barrel liner Some mounting holes Threaded the barrel block Firing View Quote |

Nice.
Here's what I put together Sunday night: Attached File Just chopped off the tail of an eBay AR trigger jig, everything bolts up. Need to throw a .223" upper on it, see if I get ejection and bolt lockup. AR57 upper, here we come! |

Nicely done! Building single shot pistols is a great way to practice skills and craftsmanship, and gun buybacks make a nice way to offload mistakes or earlier designs as your work evolves.
Personally I learned to work on stocks by making pipe shotguns (ala TM31-210) by carving and finishing stocks made from logs, 2x4s/2x6s and plywood. Also got to test several such guns for longevity as useful firearms and improving on the designs. (as a fun note, a better trigger can be made by using a medieval crossbow "nut" style trigger to hold the striker back) Sadly, the buybacks around here don't pay worth beans now days, you use to be able to make good money/gift cards off those things |

Dang, nice job. I have to start looking in here every day and keep up instead of getting distracted by work and my own projects.

I really like homemade guns.
Interesting build, using common hand tools just proves how "simple" it can be. |

This thread reminded me I have a 12"x12" piece of 1/4" steel in my garage I purchased with the intent to build a few single shot handguns out of.

This one is the simplicity and cost. It's still a lot more time than the end product warrants, but I've wasted more time on less. Plenty more projects and ideas in the hopper. But the wish list is long. Like a gatling gun. I'd love to make some dies and start cranking out WWII Liberators. |

Awesome! I recently saw that video and have been considering some homemade gun designs. I've got a pretty well equipped shop to work in but I always seem to be too busy with other things!
I'm also torn between a simple gun design like this or working on a black powder cannon of some sort. |

When you start getting serious about it, let me know. I have some stainless I could donate. http://i1023.photobucket.com/albums/af357/ligaf2000/20170406_202254_zpseqtj2clv.jpg View Quote What other designs have you looked at? I was planning on messing with the JACO stuff but instead of 22LR make them in straight walled rimmed pistol cartridges. I really do want to make a Kirkit25....but probably in something a bit more powerful than 25ACP. |

View Quote In ohio, besides slugs, only certain pistol calibers are legal for deer hunting, so a 38/357 rolling block or Stevens favorite type single rifle is on the short list. |

For those not keeping up with his builds post ARFcom, sixtysixdeuce built a GB22 in 380.

Nice, keep us posted. I'm trudging through all the woodworking projects before kiddo #2 is born. Might actually get my bandsaw frame built before the big day...if I'm lucky...

Why does that look like a 22 blank? Yet possibly a hole in the can? It's hard to tell as it's never seen clearly but maybe for a frame or two. Did you put a .22 pellet in the barrel and then chamber a blank and fire it?

Did Mark Serbu ever get a reply from the ATF to the letter he sent?

If anyone wants to try their hand at home-rifling a GB-22 barrel, here is a video about a DIY method using EDM:
Electro Discharge Machining (easier than it sounds). https://m.youtube.com/watch?v=ixwAVj9fCoA |

Mark Serbu's excellent video did not clearly show HOW he rifled the barrel on his prototype.
Anyone know? And what about the plans for the "closed bolt model" ?? ETA? |

View Quote The 9mm build I'm working on (back-burnered) will be closed bolt. Even if I finish it before Mark releases his kits, I'll still buy one if it comes in at or under $100. I'm no engineer, but I can re-engineer everything! |

Here's a review from the SHOT show:
http://www.tacticalfanboy.com/2017/01/21/shot-show-17-serbu-firearms-gb-22/ Anyone know if the plans for the "closed bolt" version are available yet? |

Hydro jet or laser cut would be good. Jack Squat could certainly laser cut a weld together version.

Finally did some cold bluing. I didn't bother with the slide serrations, yet. http://i1023.photobucket.com/albums/af357/ligaf2000/20170608_200609_zpsxauz0rkp.jpg View Quote Q. Do you think the design could be adapted to making the barrel and "bolt" out of regular Rebar or reinforcing bar used to reinforce concrete? |

This thing was a hoot to shoot at the HTF Grub-n-Gun. Kiddo's liked it... A lot.

Another rifling video: super simple and do-able with tools you already own:

Can it be done at home? Yes. Can it be done well enough to yield accuracy comparable to commercially available products? Probably not. But in respect to the topic at hand, there are plenty of techniques for boring and rifling your own barrel. With a little patience and effort, you can certainly make a 3-4" 9mm barrel that won't keyhole 90% of the time.
I drew up some plans for a sine bar style rifling jig. But with a pile of other projects, one with very little payoff doesnt make the top of the list. Watch ebay and numrich for barrel blanks or cut offs. $10 or less you can score enough to make 2 or 3 pistols. |

View Quote Also - I checked out Brownells for "22 LR Barrel liner" they suggest "glueing" it in with their "Accra-glass" bedding compound (it's really just fiberglass resin). You could use epoxy or simply "JB Weld." It cost just $30 or so for about 3 feet of it. |

That is exactly what I used in this. Redman liner. I usually accraglas them in, but this one I soldered.
