Tape the brake off for vise work as not to mar the finish to much..

 

 

use #29 drill bit (comes with 8-32 IRWIN Brand tap set at Lowes $7 or so)

 

 

tap the hole with 8-32 tap (included in above kit)

 

 

 

Crown 8-32 x 3/16" setscrews $0.70/2pk at lowes or HD I forget... perfect fit.. IMHO..

 

I also used RED loctite on the threads of the screw and barrel threads..

 

 

Tada.. grind flush and add a WELD (try a mig it works great for a tack)..

 

 

I hope this helps some DIY on here

Very nice . So all it takes is a tac? I alays wondered how everyone hid their welds so well.

ADCO replied on AR15 that a weld over the screw is GTG.. not that I'd say thats gospel..

 

but a tack-weld, and RED Loctite on the barrel threads, and the screw threads would make it additional PITA for most to argue that you ONLY tried.. IMHO..

i have seen in another thread ar15.com were they used a piece of coat hanger instead of a screw for the pinn and they put tac over that, not sure if that's ok in good ol' nj...

How do you guys do these welds yourself?

One would assume they have a welder.

 

You can buy a crappy mig welder at harbor freight for $95. Its not like this use remotely approaches real welding in terms of worrying about duty cycles/durability/etc. , so the $90 welder will probably do.

What I would really like to know is if anyone is using one of those cheap HF inverter Tig welders for lite use?????

me too!

I found another place re-opening online soon that also will be doing this and the bayo-lug thing..

 

AccessoryArms.Com .. can't check the prices from work.. buts it seemed less than ADCO and includes shipping back to you.. (which ADCO has to figure out)...

I have a 115v ESAB stick/TIG set up if somebody wants to try it. All you need ia an argon bottle as I only stick with it.

If you don't mind, how much do they go for?

Call your local welding supply because I don't know.

I use a 220 volt mig with flux wire ,, Some people hate the flux but if you use it enough you will get good at it.

My flux welds come out better then most peoples.

 

The set screw is a nice idea.

hi guys need a quick opinion, I did the first part of my brake pinning project, I drilled a Hole in my muzzle brake, I dimpled the barrel, I then threaded the hole, I put a little Allen screw in the hole, the screw was sticking out a little so I counter sunk it, figured it didnt matter and would make it easier for weld to drop in. i made sure it was good, I took a wrench to the brake it didn't move at all. anyway I took my barrel to local gunsmith to get a drop of weld but I was told it was done all wrong, that I should have left the screw sticking out so the weld will drip around it, that I should have used locktite that I believe is not totally necessary by law as it is written, he said some other stuff bla bla bla, he wants to charge me 55.00 to redo it, I left the barrel there for him to do the job but it kind of left a bad taste in my mouth driving home... here is a pic of the work I did which I thought came out really nice. do you think I should just get my barrel back and go somewhere else for a quick drop of tig or just get a simple welder from harbor frieght which im leaning towards or should I just let him redo it his way either way it will get done but I just wanted to do everything on my first ar rifle build myself...

 

IMHO I would go get the barrel back from that 'smith asap and find someone to just throw a quick weld on it.

yeah, i called him back already and told him i would pick it up tomorrow... i doubled checked alot threads, and i did it right...

 

I thought this was a cool read...

whose barrel is that?

its my barrel! lol! but if you want to know who made it its dez arms. they make some really cool barrels and ship extremely quick... I know I know before anyone says anything it's not chromed lined, but I'd rather have a little more accuracy vs easy cleaning, it's not like I'm gonna be shooting thousands of rounds a week...

That works too, the coat hanger wire is nice ebcause it's soft enough to upset with a punch and really compress into the hole in the barrel and the brake.
