Do you have threads checked for alignment?

If anyone wants to check at home for a reasonable amount of money, you can get tightly toleranced ground to diameter (not extruded) tool steel rods from McMaster Carr for this purpose.

I bought:
8893K193 Tight-Tolerance Multipurpose O1 Tool Steel Rod, 0.2188" Diameter, 3 Feet Long
8893K219 Tight-Tolerance Multipurpose O1 Tool Steel Rod, 0.2969" Diameter, 3 Feet Long
8893K191 Tight-Tolerance Multipurpose O1 Tool Steel Rod, 0.2120" Diameter, 3 Feet Long

The first is good for .223 / 5.56, the second for .308 / .300blk (with a tiny bit of play), and the third for .22. The cost for all three of these shipped next day to my house was $22.98. They may not be as "perfect" as the very expensive gauge rods that are out there, but they're good enough to let you know if you have a problem or not.

Thanks Hawkeye! Ordered.

Before using a rod, roll it on a pane of glass. If it rolls smoothly it is straight. If not, you may be able to gently straighten it until it does.

They are dicks.

I sent out a Lilja .22 barrel to Long Rifles Inc. They threaded it, made a thread protector, and Cerakoted in ONE day.

Round trip was a week.

Probably not a bad idea to also file/sand the end that will go through the muzzle. They might be rough or bulged at the ends.

I greased them as well.
