I'm looking at buying a 14.5" upper and having a vortex pinned.  What's involved with pinning an flash hider on?  Is it something any gunsmith could do?  Anything to watch out for?

Thanks

if its a good smith there shouldnt be any problems to watch for.

ADCO will do this. Check there website out for pics

I like the 14.7+ and the 14.5+

Also BCM might have it instock

I have a 16" BCM upper AR currently.  I'm looking to order the smartgunner Daniel Defense deal they have going right now.  The Vortex comes pre-drilled.  I just didn't know if it was something simple to do or not.  Thanks

I had the same question as you, and searched and found a couple different answers.

http://www.ar15.com/forums/topic.html?b=3&f=4&t=407395

I am going to go with the SS technique as I already have the MAPP gas, and all I had to do was order some SS paste, and heat paste.

Also ordered through SmartGunner.com, and went with the build your own upper, and got a 14.5 with the YHM 5C2, just going to perm attach it myself since Tommy said they do not do the pinning anymore.

if SS means silver solder, im pretty sure its not an atf approved method.

I just had ACDO do one for me.

I can't even tell they pinned it they did such a great job!

Yeah, doesn't show much, nice and neat.
Someone here opined that you want it to show at least a little bit, in case you are challenged about the length of your barrel.

FWIW, I have a L1A1 that I bought from a dealer during the the ban.  It came with the muzzle break silver soldered on the full lenght barrel.  So why wouldn't silver solder be accepted in this case ? ( to make the barrel conform to the 16" lenght)

It's LEGAL!!!

If you do the footwork yourself, its easy and cheap to do.

I drill the hole in the flash hider, attach the flash hider, then I drill again but into the threads this time, very carefully.
After that you can drive a pin in place (making sure it sinks into the threads).
Take it by a welder and have them make a small bead over the pin.
Smooth it over with a file, etc, and touch up with some blue.

The guy who does mine charges 5$ each. I also get to drink a beer while he works.

I can see mine very easy
Glad they are doing a better job !

I used to pay for the cut and pin and weld service, but now I bought a harbor freight home welder and I buy factory 14.5 barrels and then do my own pin and weld. It is not hard at all.

I figured it would be really noticable. I actually had to look really close to find the pin. It's nice and flush and if you weren't looking for it, you'd never see it.

If you have access to a TIG welder your end product will come out much nicer

I am leaning towards this method but with the SS method you can more easily rmove the fh if something else catches your fancy.

If you have an oxy-acetylene torch, then you are GTG.  But if you don't then I would invest in a TIG welder.  Propane and/or MAP gas isn't going to work since you'll have a hard time getting the compensator/barrel threads hot enough.
