I have a Noveske KX5 that is pinned and weld to my barrel. The pin must be pretty hard steel because I am struggling to drill through it. I am a mechanic I have access to a lot of quality tools and drill bits. What can I do to get this thing off without destroying it.

I called around to find an armorer today but everyone fairly closes doesnt deal with this kind of work so being me I attempted it myself. The job would be easy if it where not for the hard pin. I hardly maid a dent in this thing so far. I need to get it off so that I can replace the barrel nut. I am about to cut the dang thing off and purchase a new KX5. Lol it might be cheaper than what an armorer is going to charge.

Good luck.

I always end up grinding half the muzzle device off trying to get the pin out.

the BATFE concept of a pinned and welded is that it does have to be destroyed to remove!

I tinker and tinker and tinker and cant stop. I will be pinning my own for now on. Something I can drill through just in case my urge to tinker comes back.

Also I have a chicken named Ronin.

Are there any Armors near lancaster willing to do this, type of work? All the gun shops I have called so far dont seem to do anything pin related with muzzles.

Post a message in the Hometown section for your state and see if someone there has a idea.

I've unpinned a couple, and had better luck drilling holes on either side of the pin. Use those to get hold of the pin and pull it out. Rewelding after repinning fills the holes I drilled.

It's probably not the right way to do it, but it has worked for me.

You need a machine shop, not a gun shop.

A dremel with a very small grinding bit works, but takes time and patience.

You need a carbide end mill, a mill and a machine shop. I have saved several muzzle devises by using a carbide end mill to mill out the pin.

I found a shop in gap pa that says they can get it done. It's about a two week turn around but it will be done.

Send it to these guys: https://www.adcofirearms.com/shopservices/

They do excellent work, with a quick turn around. I shipped a barrel to them last week, arrived at their shop Wednesday at 10am, and I had a return tracking number at 1pm same day.  It was in my hands 2 days later.

You really wanted a new muzzle device anyway...
Mine get destroyed

You won't get the muzzle device back. They basically grind it off. At least that's how they used to do it.

As a mechanic I'm sure he has and knows how to use a cutoff wheel, just a little care and the muzzle device will split and separate.

They're right.  Right tool for the job.  Otherwise its a DIY.

Cut off wheel would be doing it wrong considering I want to keep the KX5. I realize I need a carbide bit to remove it. I don't have one and the drill press I have is pretty antique. I am probably going to outsource thus job to a guy in gap pa that has experience doing what I need. Even though everything in me is telling me to go get a carbide bit and do it myself.

It's a factory pin and weld from noveske.

If your drill press spindle isn't rigid enough (most aren't plus the chuck/spindle may have a lot of run out) the end mill will wander off center and you can chip or break the end mill.

It would take a regular machine shop about 15 minutes max to mill the pin out.

OP if your the type of person who likes to tinker with the rifle a lot I would suggest buying a 16" upper. I built my 14.7" upper for HD use, then bought a 16" to tinker with.
