Flash Hider pin/weld to barrel job

[Guest JCothron2]

I need someone who can do this fairly quickly just put my 14.5" AR together with a BattleComp 1.5 FH, need it pinned to make it legal, any help is much appreciated. Looking in the Nashville Area.

Welcome to the forum, Mt juliet myself.

Can not help, do not have a TIG or way to drill and pin.

Nor do I have a place to send you, Reloaders Bench?

Another option is to solder the joint instead of pinning and welding.  Brownells carries a paste that is high temp silver solder mixed with flux.  Clean threads apply thread on flash hider, heat with torch.  Not terribly dofficult but if your not carefull you can end up with a brittle bond or discolor your barrel/flash hider.  If you choose to solder it it has to be high temp silver solder.

 

I know nashville armory has a gunsmith they work with but havent personally had any work done by him. 

 

Jeff walle at guns and leather is probaly one of the best smiths in TN.  His shop is still next to the greenbrier location, which had an unfortunate fire a little while back, but IIRC you can do drop offs at the hendersonville location.

Ha, wouldn't it work if you applied the solder then sent 100 rds down the barrel in quick succession?

TMF Possibly if you used the cheap low temp solder.   ATF requires it to be high temp (1100 degree+) silver solder to meet the defnition of permanantly attached.

Best take the stock off till its pinned , with a stock it's a SBR.

Or just remove the upper. Edited February 26, 2013 by Threeeighty

Didn't know that. I'd think getting over 1100 degrees would surely discolor the barrel and flash suppressor, wouldn't it?

theres a possibility of discoloring the metal.  Some have had great results others not so much.  The best results i have seen used the fusion paste as well as a heat stop paste.  Apply the heat stop paste on the barrel apprx 1/8 of inch past where the FH stops and apply it to all byt the last 1/8 inch of the FH itself.  That way you are only exposig about 1/4 inch of the metal to the torches heat.

 

Edited to add:  Soldering also has the additional benifit of being easy to remove.  Vise torch and wrench are all thats needed.  It also prevents from having to drill a second spot in your barrel if you ever choose to replace the FH.

You will need to use mapp gas to get it to the right temp. have put on about 60 flash hiders and I use 80PA Silver Braze.

Have you done this yourself yet?

[c.a.willard]

Havent done it myself yet.  Havent really had a need for permanently fixed FH.  Had a budy that used it for a rifle that he was waiting on a stamp for. I think he did have a little discoloration but not much.  Ive silver soldered some other stuff just not gun parts.  Started looking into it more when i ordered a PS90 because i think im gonna pull the barrel extension and permanently attach a fake suppressor to meet the required length  thats if the thing ever gets here.  Been waiting since early december so i've had alot of time to go through videos and tutorials

any recommendation or updates on who does quality pinned flash hider in the middle Tn area?

[gjohnsoniv]

Outpost Armory does it. Can't speak for their quality though. Think they charge 20 bucks.

Thank you sir... Anyone else ?

[justincase]

anyone else have a good local gunsmith?

[quedz]

Bump!

If they charge $20 with refinishing I dare say you won't find a price cheaper anywhere. I've done my own (only 3 though) and I wouldn't do one for less than that. I've welded mine, no reason to mess with that other stuff if you can weld IMO Edited December 16, 2015 by KKing

Silver solder a gun barrel ?  I'm a plumber with 20 years of experience and I have silver soldered many joints in copper pipe. I have to get the pipe glowing cherry red to get the solder to flow . I'm dumbfounded.

[justincase]

and I found out the Outpost Armory doesn't do this type of work as of last week. I did find someone local to do it though... I will let you know how it turns out and will post more info then
