I pinned and welded an extended flash suppressor to a barrel yesterday to make it a legal length. Everything seemed fine, but then I looked through the barrel an saw that the pin went into the bore slightly. Its very slight and just thought it was dirt at first. Is there anything that I can do or is this barrel junk now?
Thanks |

Have Adco chop and thread the barrel behind the intrusion. |

you could drill out the pin and repin it without it protruding. it may not have much of an impact like a gas port.

Probably still shoots to .mil specs. May shoot slightly to the pin side. If you did it to someone else's barrel, then you should buy them a new barrel and practice on your barrel until proficient. Shoot it and see. probably will be fine, but won't be "precision" |

I wouldn't call the barrel "junk," .... Just a little bit shorter and a little lighter in the pocket book (unless you have a lathe). |

I may be able to drill it out ok, tap the hole of the flash suppressor, and use a hex screw instead of a pin. Thanks Boywonder!! By the way, do you have an H&R BCG that you would be interested in selling? |

Re-do the pinning job correctly (no protrusion) and see how it shoots. The area will cover in carbon fouling and probably be fine, imo. View Quote View All Quotes View All Quotes Quoted:

I'd suspect the later, considering the location is so close to the muzzle. I would not be content with this plan of action, especially on a retro build that requires leg work and attention to detail. Treat people the way you want to be treated.... |

The area will cover in carbon fouling and probably be fine, imo. Think I will try this method! Thanks I don't know if this would be such a good idea. I would be wary of gas escaping from the hole left in the barrel after you re-pin it. If you go this route, be very careful when you shoot it for the first time. The extra escaping gas near the gas port could cause some cycling issues at the lest or damage to something at the worst. If there is no gas leaking for the first 100rds or so then it should be fine. I know I may be a buzz kill, but I don't take chances with damaged barrels. Barrels are going to be pretty cheap with labor day coming up. I know Primary Arms is having a big labor day sale. Numrich has a pinned to 16", 14.5" barrel with an izzy flash hider for $130. https://www.gunpartscorp.com/Products/1503160.htm |

What's the barrel profile, current length, etc? View Quote The barrel is a standard Colt M4 barrel with a length of 14.5 inches. I was able to get the BCM extended flash suppressor off and removed the pin. I ordered a new flash suppressor for it. Will use a hex screw instead of a pin this time. I am hoping that there will be no effect as the bullet as it leaves the barrel. |

I misunderstood. I was thinking the botched pin job was for the front sight post. If it is near the end of the barrel and the new pin and muzzle brake will cover it, then it will be ok, just make sure there is no intrusion into the actual bore.

Ignore anyone that says the barrel is ruined/accuracy will be awful. NOBODY can tell you if it will shoot accurately or not, you will have to check it to know for sure. Just remove the botched pin/'hider, install another and pin it in another location, weld/smooth it down.

Just an update. I removed the old pin and ordered a new extended A2 flash suppressor from BCM. This time I drilled out the existing hole and used an 8-32 tap to use a 8-32 x 3/16 HEX screw instead of the tiny pin that they supplied. I then welded over the hole to permanently attach the flash suppressor. Took the rifle to the range and it shot PERFECT tight groups. Thanks for all of your help and opinions on what I should do.

Honestly, you were good to tell the person what happened, but you should have said you will be replacing the barrel at no charge to make up for it.
Even though he said he was "happy" with it, I don't believe he was 100% fine with the outcome. It still doesn't change the fact you messed up the barrel and should have replaced it. Just my 2 cents though. |

Not a customer, a friend of the OPs. View Quote Guess I was raised differently that when you break or damage something of another persons, you fix it properly or replace it. Covering the hole is not 'fixing it' as far as accidentally drilling into the barrel. The hole will still accumulate powder and copper jacket residue. Anyone who argues this is an acceptable "repair" should not be working on firearms. |
