Suppressor Alignment

Through its S.I.D. kiosks, Silencer Shop has made buying a suppressor as easy as ordering a hamburger at a fast food restaurant. Once you have your suppressor, one thing you want to make sure of when you mount it is that it’s properly aligned.  If not, you can have a bullet/baffle strike.

Remove the bolt and clean the bore, then push the suppressor alignment rod in from the chamber end.

Fortunately, checking alignment is simple.

It’s not the most sexy looking tool in the armory, but a suppressor alignment rod is very important when first mounting a suppressor.

Remove the bolt carrier group and charging handle, then clean the bore. Take the appropriate diameter suppressor alignment rod and simply slide it down the bore from the chamber end until it just sticks out from the muzzle of the suppressor. The small gap between the alignment rod and the muzzle should be concentric all the way around.

Let gravity slide the rod down the bore until it just protrudes from the suppressor’s muzzle. Check to make sure the gap around the rod is concentric.

You cannot use just any old rod, such as your cleaning rod. Alignment gauges are precision ground and checked for straightness. If your suppressor doesn’t align, then you need to take everything to a gunsmith who may be able to reface the shoulder of the barrel. If your bore is off-center though, you’re probably screwed.

This YHM Nitro 30 suppressor is so modular it suppresses gun up to .300 Ultra Mag., is full auto rated, and fits threaded or QD-style muzzles.

    Thanks for touching on this subject. A couple of things to add. You can buy drill rod from McMaster Carr that will do the job of the precision ground range rods. They come in sizes that are close enough and they are three feet long. They may not be perfectly straight but if they will slide down the bore they are good to go. The extra length helps with the longer cans. One of mine came in slightly curved but I straightened by eye like I used to do to my aluminum arrows. If your muzzle threads are not concentric with your bore you are not SOL. Remove the barrel from the action. Face the threads off shortening the barrel by the length of the old threads. Set the barrel up between centers on the lathe. Turn and thread the muzzle end with new threads. Oh and remember to recrown the muzzle.

    • Good info. Doesn’t hurt to have a cheaper “test” tool to confirm a diagnosis or rule it out.

      I love how easy you make it sound to cut, re-thread and re-crown a barrel. Sir, I wish I had your machine shop in my garage.

        I do too! My garage is inhabited by some wood working machinery. Was a machinist for 35 years and luckily have access to a small lathe and a Bridgeport when needed. Like most things machine work is all in the setup. Have crowned and threaded numerous barrels through the years. Will eventually get another lathe and a good mill.

        • I have to be honest. I read what he described, but I wasn’t really following. Glad someone else was.

          I just shoot the guns. Someone else fixes ’em!
