Proper suppressor alignment

[Mr. Booshie]

ended up ordering a 9mm rod from https://accuracy-solutions.com/

i have 3 diff mounts to test with...then a call to sico i guess. my YHM r9 performed stellar. right at $500 OTD after stamp...the omega 9k was more...

FYI the rod is too long for the APC9, I found out the hard way. The case extractor won’t let the rod go through the receiver.

I use a Rugged obsidian 9 with their mount. No issues on my PRO.

I’ve seen people say they get strikes about everyone but Rugged and CGS 3 lug mounts.
People have complained about strikes with the rugged mount used on a obsidian 45 but not the 9.

The issue you’ll find is 3lug allows movement, if the inner sleeve of the 3 lug isn’t tight tolerance, you’ll have more movement than you should and you’ll have strikes even if the rod shows it’s good. When you use the rod, check, shake the **** out of the gun and check again.

This is the reason I got a B&T RQD can for the APC. It ratchets down and won’t move.

my shorty apc9 has a cherry bomb on it with a YHM r9. no issue there. the longer one with the 3 lug is the bitch right now. I have a rugged 3 lug mount I can try as well.(it seems looser, maybe that's better?)

IF the rod shows the can out of alignment...I assume sico is ez to work with? I am also going to try it on the shorty using a plan B mount like my r9 wears.

I took out my apc9 pro to try out my sico omega 9k today. I am getting "kisses" on the very edge of the exit aperture, endcap whatever. couple of shards of bullet jacket shook out. I cannot see any damage to a baffle...just a tiny bit of copper fouling on the inside edge of the endcap hole.

b&t 3 lug barrel, griffin 3 lug adapter.

anyone have suggestions or a 9mm alignment rod before I order one?

thanks guys.

Call GA firing line, I got 556 and 762 geissele alignment rods from them yesterday in case you dont wanna wait for shipping

McMaster Carr.

Mine was bent from McMaster Carr. Straightened it out well enough to work though.

got the rod today. 4 diff mounts, 3 diff hosts...the rod is biased towards where the rounds are kissing. I tested another can(sico octane 45 hd) on the host in question, seems very well lined up. going to contact silencerco.

Glad you got it figured out.

Let us know how SiCo responds. I have an Omega 9k in jail for a year now.

Spoke to the ATF yesterday. Mines been in jail 400+ days. She said the issue they're having is they don't have enough Examiners. Each Examiner is assigned 100-150 cases at a time. The problem is they are handling everything from FFL/SOT compliance and discrepancies, to stolen firearms, to licensing violations, and Form 1-4s. So if a particular case is sucking up time (such as fraudulent FFL inventory) then all the others have to wait.

Mine was cashed on 3/24/2021 and was JUST assigned to an Examiner on 5/6/2022. Meanwhile, some people have gotten theirs back in less than a month. It's pissing me off.

I'd lean towards the threads on the barrel rather than the can being out of spec.

4 mounts 3 hosts. got RMA info from sico. mailing it tomorrow.

I've destroyed 2 silencerco cans and they took care of me.

Here's the part numbers for what I ordered...labeled by caliber. They all worked perfect, and saved my a$$ on a few misaligned adapters. Used a grinder to round off the edges and smoothed them with fine sandpaper...also put labels on one end for easy identification...
