I asked him what the brand of the rifle was. He said he didn't know. I just told him to look on the gun and it should say the brand name or manufacturer. He said he couldn't find anything. Anyway he brought it over and i started looking all over it and couldn't find a brand name. He bought it off a state surplus auction site. Here is where it gets weird. I found the serial number. It looks like an after the fact serial number hammered in by somebody who didn't care. The first three letters of the serial number are "ATF". I told him i think he bought a homemade 50 cal that was confiscated by the aft but somehow wound up on a state auction site. I would assume if the atf got it, it would have been destroyed. I told him to be careful when he fires it for the first time. I do have pics of the rifle but forgot to get a pic of the serial number. I don't know how to post pics but can send it to someone to post. Any thoughts on if the atf does serial numbers but then releases the rifle back into the wild? Was it like this?  |

There was an old AR manufacturer that used the abbreviation of C.I.A.
This sometimes produced humorous results at the fun show. (Rando drunk wobbles up to the table) "Wanna buy a gun that belonged to the C.I.A.?" (This is where would explain it to them but you're out of crayons. So you just laugh.) |

Quote HistoryOriginally Posted By DarkLordVader: Some clown at a local range brought in a .50bmg and setup. Before he does anything he asks me if I wanted to shoot it. I was like sure, go ahead and send a few down and I will try it. He say no, I want you to shoot it first, I have never fired it before.  I declined the offer to be his crash test dummy. Wow that dude has a set a balls on him. A hi ho fuck you should have been the reply! |

The ATF declared Maadi-Griffin kits as firearms even though the ATF only tested them with blanks and not live rounds. I can shoot blanks from an aluminum tube but would not want to fire live rounds that way. Then he Maadi-Griffin screwed up and tried to hired someone to kill the judge.

I may be wrong but wasn’t that Burt’s rifle in the 2nd Tremors movie. The one he shot the shrieker and engine block with?

Mine has been fired with the 1000Gr bullet proof load. No issues there is SO much meat on that action, and the lugs are way over sized.
It was a fun project, in the shop some where I have a second receiver and barrel. to build a pistol.

Quote HistoryOriginally Posted By Ridgerunner9876: I would trust yours. I watched your build thread. I built one kinda like the SWAT actions Klaus Horstkamp used to build. 17-4ph at 45-47 Rc and over built by about 4x. I trusted that one.  Ultramagbyron had a sweet falling block .50 half built by an old school gunsmith friend of his. I tried to buy it from him but he wouldn't sell. Caught up to him on akfiles and he had sold it....fargin bastage. |

Quote HistoryOriginally Posted By backbencher: It's a Maadi-Griffin, down to the ATF dictated serial number. According to ATF, it's not a homebuilt. AFT went after the rifle "kits" they sold that were deemed more than 80% or some other factor. People that had them were contacted by AFT and informed they had to apply an approved serial number or turn over the kit. My shooting bud had one and was contacted by AFT and those were his options. Home built 50's can be fun....

50BMG or any magnum rifle are not for poors… buy something reputable or end up like that youtube guy who almost blew his face off (granted that one was due to counterfeit ammo)
His best option is to deactivate it and use it as a display piece. |

Quote HistoryOriginally Posted By Ridgerunner9876: Doesn't really matter if it holds together once or 10 times. Without knowing the material, heat treat, and some other stuff that isnt hard to measure if you're in the trade, you could just as well be setting up stress fractures or metal fatigue. Tell him to watch the Kentucky Ballistics video of a .50 coming apart and nearly killing him. I wont comment on Scott's wisdom in his course of actions that day. Glad he came through it. Yeah, using slap ammo on a firearm he knew ge wasn't supposed to use slap ammo on is the same thing. |
