I have a Battlecomp on the end of my M4 barrel that is pinned and welded to be permanently attached. The weld spot is a bit "rough", as you can see here...

 

 

 

 

Was wondering if someone could offer any suggestions how to best fix this so the spot is smoother? I'm in Morris County.

 

Thanks in advance!

Holy crap who did that weld? Looks like a mig weld and they forgot the gas, and then went nuts with the grinder. PM inbound

But the guy a Sears said the Flux-cored wire was just as good...

you gotta put before and after pics... I asked once about flux welding a muzzle and it wasn't recommended, I understand it should be tig? does it really matter? harbor freight always some cheapie welders sale...

Tig will yeild the cleanest weld and coolest weld. Thats what I use (JETagent)

Always Tig, but watch out as the battlecomp is stainless so cold blue will not refinish it well.

can someone post a nice vid of a muzzle brake being pinned welded, checked YouTube nada!

Thanks for the replies. Someone out of state did the job. I'll leave out details though.

 

JET, replied to your pm.

First couple minutes of the video:

While the cheap ones from them will do ok with some light material and if you don't use gas you will get a lot of splatter, all I will say is you get what you pay for.

File it smooth and use cold blue or duracoat?

Damn, that's pretty bad.

 

I will gladly say that JetAgent has done numerous modifications for me and his welds are really nice and clean...

so where are the after pics?
