Checking Suppressor Concentricity

[General RE LEE]

Anyone got a method to check the concentricity of a suppressor to the bore that doesnt involve these $50-$100 machines rods?

Are you wanting to simply make sure the bullet will clear the baffles or actually measure concentricity?

I don't want baffle strikes

Screw it on there and look down the bore from the action end, if it's out of spec it should be pretty obvious. Carbon arrow works well too.

My Gold Tip XT Hunters 300 may be a little thick for that lol

I hear you. I had baffle strikes on a Cooper (threaded by Cooper), so I purchased 3 or 4 rods (for various calibers). And while my memory could be wrong, I don’t think I paid that much for all 4. I can check or try to find the order later if needed.

Awesome. I saw a set on eBay but I'm a little skeptical.

Well geewhiz is your guy!

You can buy steel rods from McMaster-Carr and cut them down to size. Much cheaper option.

I had "technical difficulties" that day that I think I could get away with blaming on someone else.

What caliber rifle(s)?
You can buy 6mm, 7mm, 7.5mm 16” stainless rods off amazon fairly cheap, just like Mcmaster. Just need to soften the edges with sandpaper before use.
Might not fit real snug, but the length is enough that they dont have much wobble and work fine for the job.

You can also wrap your cleaning rod with painters tape in a few spots to fit snug as well if you have a straight rod. Mines carbon fiber and fairly straight.

Was gonna recommend this same thing. I believe their around $7 a piece. Also any smith who cuts and threads barrels should be able to check it for you as well.

Aluminum rods work great, soft so they don't ding the bore.
