Guy had a 12.5" upper and did not want to go the get in bed with the gov route and asked me to make him something to get to 16.25 and he also wanted a suppressor look so found a chunk of aluminum bar in the bin and turned the OD to just barely fit under the handguard then bored the ID out until I thought it looked right. I mistakenly bored the entire thing out forgetting I need something to thread lol so I turned another smaller one and tigged into place and then drilled and single point threaded that to be concentric with the tube. Chamfered everything, media blasted and went ahead and plug welded it to the barrel (I used a threaded set screw then plugged in aluminum on top for this one. I was going to blend off the tig marks but it would not looked welded on so I decided to leave that. After that I taped up the bbl and cerakoted in graphite black.

Good looking end product, but weird choice by the customer IMO.
How much does the extension you made weigh? |

Quote HistoryOriginally Posted By OG1: was going to make that and weld on end caps but I don't know if that is legal or not. Seems it would be, I remember seeing surefire trainers with welded on caps but I have no idea. Final product looks great but I would definitely forego the end cap. All of the SF trainers that I have ever used were open like a blast can. It’s my understanding that the end cap is a no no and constitutes NFA territory. Of course, the FATF is clear as mud on everything, so who knows. ETA: SF trainer link - this is what I have used but maybe there are other models with end caps. IDK |

Nice work, OP. Sounds like a .308 at an indoor range.

Nice. Prettier than any I've made.
I still prefer the pin and weld bayonet. Welded to the barrel, makes it legal length. Win win ! |

I can't believe the ATFE accepts that the bayonet contributes to the length of the barrel just because it's "permanently" attached. Is there a determination letter on that?

Is there a determination letter on that? Not sure, but I think, since it's not threaded on, it has to be welded. And because it has to be welded it has to be a bayonet type that has a ring like any of the issue M4 bayonets, M6,7,9, etc. Because it has to be welded "around" the barrel. Pretty sure I saw one welded onto a threaded sleeve, which was then, threaded on to the muzzle, pin and welded. |

That would be hilarious if that's the answer to the pistol brace bullshit - just weld a bayonet on & throw on a stock? Lol.

I retired my bag gun when the aft went all in retard. I really love this titanium V SEVEN Helios blast can but will see how it goes getting a 7.5 out to 16.25.  |

The steyr MPi 69
Most fun with a full auto sub gun ever Honorable mention HkMP5 SD? The navy version with The suppressor in the forearm Set up with 3 shot burst Point the red dot, tap the trigger And three holes instantly appear Heavier than you think Tommy gun m1? Loud, heavy, other than short burst, hard to keep on target Sub gun I would like to shoot British Lanchester |

Quote HistoryOriginally Posted By OG1: I didn't weigh it but it seemed pretty light. I have some titanium tubing and was going to make that and weld on end caps but I don't know if that is legal or not. Seems it would be, I remember seeing surefire trainers with welded on caps but I have no idea. My KUSA KR-9 has a factory aluminum one and it weighs a freaking ton and I want to make a new one. It has a bbl under it however so it is purely cosmetic. No, the original GSG had a barrel shroud that had a similar setup. ATF came back like a year later and said it was a supressor. If it has end caps it will reduce the sound a couple of DB. If it does that its a supressor. There are some blast shields that have end caps that are perforated. Probably best to side with caution if you cannot test to see if it reduces sound at all. Just wanted to throw that out there. Pretty sure what you made is GTG though. |
