Anyone on here able to remove a perm attached FH to weld/ pin? I don't have the tools but I would like to remove the front sight and add free floated guards in the future. Right now it is a bit over my head. 
ETA: Or know someone who performs such services for a reasonable price in the OKC area? |

Is it a short barrel SBR or something special? My first build was during the ban, the barrel has a fake flash hider permanently installed, after the ban lifted I inquired about removal and getting the barrel threaded so I could use a regular flash hider, in case I ever wanted to install a floating hand guard or something similar, I was told by many people it would be a lot easier, and probably cheaper to just replace it with a regular barrel. |

Anyone familiar with Surefire Rocksett? Does it meet the requirements for perm attached FS and is it removable in the future? I have read a thread in the tech forums about 1100 silver solder... And I'm hoping it is actually easy to remove, there is debate.
essentially, I want to free float and lowpro gas block my AR, and I just want to make sure that the FS can be removed to perform said task. |

one would ASSuME that the same heat that melted the solder to install the FH could be used to melt the solder for removal of said device .
i have no direct knowledge of this though. the idea of subjecting a barrel tp 1100 degrees once, let alone twice is unsettling. |

It is a 14 5" with a silver soldered FS I do not have a dremel to pin it myself with. (Mid 20s and still haven't built a tool hut). Anyone familiar with Surefire Rocksett?

You're better off getting a new barrel. You would have to raise the temperature of the barrel to a point where the material may crystallize while cooling down. I don't know if I would trust that barrel enough to shoot it after I had done that. |

The first one he did came loose after a 1000 rds or so because of the silver solder paste he used. It cames from Brownells. Now he uses flux and silver solder, not a mixture of both. He resoldered the flash hider and we have shot thousands of rounds out of it without a problem. That AMD 65 shoots relatively accurately for an AK. |

i'm 99.9% sure Rocksett isn't a approved method of permanently attaching a muzzle device.
i couldn't find the official ATF rule but guys on this archived thread even seem to think Silver Solder isn't legal. http://www.ar15.com/archive/topic.html?b=3&f=118&t=509774 a quick call to Adco would probably ease your mind. its just easier all around for me pin and weld over the pin. easier to get off,too. and...this IS only to get a short barrel to 16 inches, right? you don't think all muzzle devices have to be permanently attached, do you? |
|
No, I honestly don't know why someone would perm attach a FS to any barrel they don't have to.
Thanks for the link Hotdog. Did you pin/ weld your own? Or did you take it somewhere? ETA: ADCO has quite a few services I'm seeing. Has anyone used them? Is CHA the only place local to OKC that offers similar services? |

You can silver solder but it has to have a melting point of 1100 degrees Fahreinheit.
DEPARTMENT OF THE TREASURY Bureau of Alcohol, Tobacco and Firearms Washington, D.C. 20226 JUN 18 1998 F:FPD:FTB:RAT 3311 Dear Mr. : This refers to your letter of March 31, 1998, in which you ask about permanently attaching a muzzle device to various firearms. A muzzle device, such as a muzzle brake or barrel extension, which is attached to a barrel by means of welding or high temperature silver solder having a melting point of at least 1,100 degrees Fahrenheit, is considered to be part of the barrel for purposes of measurement. A seam weld extending at least one-half the circumference of the barrel or four equidistant tack welds around the circumference of the barrel are adequate for this purpose. Industrial adhesive products are not an acceptable method for permanently attaching a muzzle device. We trust that the foregoing has been responsive to your inquiry. If you have further questions concerning this matter, please contact us. Sincerely yours, Edward M. Owen, Jr. Chief, Firearms Technology Branch |

1100 solder or pin and weld are your ONLY options.
If you are just wanting to low profile your FSB and float your barrel, I'd Dremel off your FSB and shave it down, and install a Centurion rail. It'll use a standard barrel nut so you don't have to disassemble. All you need to do is cut off your handguard cap, delta ring, and remove springs/snap ring. 30 minutes tops.
