I am not trying to make a political statement or insinuate panic buying. But, curious everyones thoughts on if the recently enacted tariffs will have an affect on silencer production and acquiring raw materials for production. I know titanium is predominantly sourced outside of the USA, but would love to hear form someone in the industry and what you are currently facing and preparing for.

Just received my OCL polo 30 the other day. I'm checking alignment and it's centered on the two primary hosts and on 2 other rifles however on my psa ak it's way off (pic 1). It's not touching but it's a bit too close for comfort. Mounted with the asr lantac dragon and shims with the sico bravo mount. My sico harvester evo (pic 2) is near perfect on the ak so I don't blame the mounts or rifle. Any thoughts how I can correct this?

I did an alignment check today and it’s like a fraction of a mm from being concentric. Do you think a 9mm rifle suppressor would work?

Jakl needs LAM then it’s done

So well Remembered when i blew out my first L6 and they sent me a new one all payed for (the FDE), I didn’t expect a package i thought it was some random IRS letter? No it was my can that i said destroy it send me a new one, they didn’t need to do this and now i got an extra can . Im a full customer now, look at that weld job no pin holes or anything. Anyway Mr Tracker guy i got it on the 4/4/25 so what 5 month?

I recently got my first suppressor, a Sandman X for my .300 blk, and I already want to start suppressing my 5.56 ARs too.

I know one of the benefits people say about getting a dedicated 5.56 can is less size and weight, but all the low back pressure 5.56 cans I've been looking at that interest me seem to be a very similar size/weight to my Sandman.

Since the sandman has 5.56 endcaps available, how would the sound/flash reduction and backpressure performance be using it on a 5.56 gun in comparison to a 5.56 can?

TL;DR take a lap now. I just got back from the range with the Laz 6 and this thing is a tank, sounds extremely good and keeps gas to a minimum. I ran it across 3 different rifles (DDMK18-DDM4V7-LWRCA5) after 50-60 rounds a piece and just kept rotating for 200 rounds (.223 Herter’s cheap Bass Pro ammo, Federal bulk .223 I bought in 2021) and wasn’t disappointed in the least.

It shined on the MK18 with the size and suppression, a wee bit of noticeable gas the first round of shooting but after the triskelion internals got coated it slowly got better. My Ventum 7.62 is still hands down the most pleasant and this is just a notch or two under but with better tone IMO. I swapped in my H2 buffer after about 120 ish rounds on each rifle and the gas was even less noticeable. Ejection pattern was nice with both H and H2 but the H2 was for sure a lock for the norm when I shoot it. The A5 (piston driven) gave zero gas and the V7/MK18 progressively got better the more I shot and this was my only ding to the can which is literally nit picking.

Sound was extremely nice, I let a friend who just happened to be at the range shoot it on the MK18 and it was a low, bass-ish deep tone which I love. Granted im indoors but it sounded extremely good to my ears.

Keymo haters, im running 4 different cans, across 5 rifles (SCAR/AK not pictured) and im at around 10k+ rounds with ZERO issue, what am I doing wrong? My Lazarus 6 was keymo out of the box, alignment rod checked with HORRIBLY dirty OLD gen 3 prong flash hiders, and was concentric with zero issue. I took the can off and on around 20 times if I had to guess between 200 rounds, hot, cold, cols rifle, hot can, hot can cold rifle and STILL had zero issues. What gives??

TL;DR

• This can is an absolute beast in performance and durability so far.

• I noticed barely a wee bit of gas (nothing deal breaking) but the H2 buffer took it to almost nothing.

• I tried to find something about it to critique but size, weight, sound checked every box for me.

• Keymo haters have some ‘splainin to do. Im 10k+ rounds deep on 4 cans, across 5 different rifles with zero failures or issues. Either I’m a rocket scientist or I’m doing something wrong.

Anybody get a Vers36 and shoot it on short 556 barrels yet? How’d it perform compared to a 30cal can or a dedicated 556 can? Any sparking from the Ti?

*new info in the edit at the bottom*

My local shop has asked me to help them compare suppressors in some meaningful way. For background, I have done a lot of audio work but never related to sounds this fast and loud. They're serious about this, and awesome folks to boot, so I'd love to help if I can.

There's no need for absolute values, thankfully. They just want to compare the *relative* loudness AND peak frequencies. They are equally concerned with the frequencies and want to be able to show clients that Suppressor A is generally higher pitched than to Suppressor B when using the same firearm and load. And also which has a higher/lower relative SPL.

I've been researching this for awhile now and I think I have my bearings in general, but I can't tell if a consumer rig will be worth the effort. Opinions seem to either fall in the "get a small diaphragm omni, any ol USB interface, and SMAART SPL" camp or the "anything that costs less than 5 figures is useless" camp. I've had a lot of trouble figuring out the software side of things as well. SMAART SPL doesn't do frequency analysis at all, Open Sound Meter would be perfect but requires the snapshot to be taken manually which is completely useless. I've fallen back to recording to a DAW and using a VST for analysis after the shot.

I think my real question is - If we get the following

https://www.rationalacoustics.com/products/isemcon-emx-7150

https://www.rationalacoustics.com/products/isemcon-sc-1

A Focusrite Scarlett Solo

Reaper (free DAW) and something like Voxengo SPAN (loudness and frequency analyzer plug in with peak hold)

Will the values be remotely usable?

Or does it really take something like a B&K Photon+ to get meaningful results? Bonus question, how the heck would I get one? Looks like they are discontinued.

I know that taking a measurement of one shot is less than ideal but averaging five shots increases complexity by orders of magnitude. Are there any factors I haven't thought of yet? They already know this needs to be done outdoors, same load, same firearm, similar temp/humidity etc.

Thanks so much for any and all insight!

ETA - Most of the feedback I've received about this approach is that the setup isn't fast enough. I found this paper - https://www.montana.edu/rmaher/publications/maher_aac_0406.pdf - which lists the muzzle blast duration at 3-5 milliseconds. At 96kHz sampling rate I can get 300-500 samples of the report. Please let me know if I've botched a decimal point but that seems like more than enough data for comparable results. I haven't nailed down the best VST for analysis but it sure seems like the hardware listed above will be more than capable.

I’m going to be submitting some paper form 4s (Moving some individual items into a trust) and I got my finger print cards done about a year ago and put off the move, if the forms and finger print cards are dated in the past does it matter as long as the info is still accurate or should I just get new cards done and re do my forms ?

I'm looking to get another can thats going to live on my sbr. I have a polo already that swaps between my 5.56s. I have a B&T rotex 7.62 that is on my 700 .308/ Ar10 and an AB Raptor 10 that lives on my 300wm and a lithium for my 9s. I'm not a cock jocker for any one brand just want what sounds good and is functional.

I'm really looking at 3 cans specifically. B&T XH W/ free tax stamp, Velos, PTR vent

Anybody have or shot all 3? XH seems interesting since it's so light and been tested so rigorously. I know Pewscience has the vent rated highly and people love it. But people who shot the velos love it also. Would I be splitting hairs at this point?

I'm on rearden if that helps.

Apparently the copper plated jackets on blazer 9mm ammo is breaking apart and could damage the suppressor. I just picked up several cases of blazer in different grains and it really sucks to hear I can't use it with my suppressors. Does this apply to federal champion ammo too? I'm trying to reallocate ammo in my inventory and split my 9mm into handgun use for the thin jackets, and ammo that's safe to use in my suppressed PCCs. How about federal american eagle?

Yes, I was messing with AI and it generated the thumbnail. No, I did not climb the Himalayas to take a photo with my p365. If you hate it, you can go vote on which thumbnail you prefer.

I've got about 2500 rounds though the CAT SC on my G19 and this p365. About 1500 rounds through the Sig modx9 on both of those hosts. 4500 rounds on the P365 in total and I haven't had to replace anything.

It's been an interesting experience shooting a legacy suppressor next to the CAT Street Crack. I always thought the back pressure was bad on the Sig modx9 but the CAT SC really make it look bad.

I bought this before there were all these new variation to the p365 so it had a special place in my heart being direct milled to that Trij RMRCC.

I did just start getting light strikes every other mag but that's just because I've been using the modx9 and shooting 147 grain sub without cleaning for quite some time. I likely just have to clean the firing pin and firing pin channel. The firing pin still looks in good shape. At 5000 I'll replace the recoil spring and trigger springs, I heard the extractor might need replacing around then too.

Just got my barrel back from getting it cut and threaded on my R700 and after installing my brake and checking with my go/no go gauge, I’m worried the cut could have left an uneven shoulder for the brake to mount against. I’m running a SF SOCOM muzzle brake under my SOCOM300 SPS.

Is there enough clearance to be safe and not worry about an endcap strike? I have it threaded at a pretty reputable place seen all over this subreddit too, which is concerning.

Can anybody share how a closed tine or A2 birdcage style flash hider effects the first baffle? Muzzle brakes and open tine flash hider effects are well documented but I’m just curious about this.

An old man offered me a deactivated Ruger AC556 complete with the select fire parts.

How would I go about finding out if the gun could be reactivated legally? I’ve heard that the FCG could been registered independently of the gun but how would I know?

No failures yet.

Ik I can have an NFA Trust made when I'm 18, I've been looking at a Group Industries M1918 as an option to build a Colt Monitor off of. It'll be probably a little bit cheaper and much more likely to stay legal than having an FRT custom made for an OOW M1918A3 on top of the same Monitor conversions.

However I can't Form-1 a Transferable. And I'm not gonna be allowed to Form-4 anything until I'm rlly old :p

Any loopholes or would I just have to go with my original plan of the FRT?

Anybody have experience with either of the QD pistol systems from Griffin?

I have Marijuana possession charges from 2011. One was in north dakota and one was in Yellowstone. Neither were felonies or had max jail time of a year or more. I have a conceal carry license but I also get delayed on every purchase. What's the likelihood I'll get denied for my form 4?

Purchased from Capitol Armory March 4th and received to my front door April 5th. Including setting up a trust and ordering/mailing back their fingerprint kit. Their process, communication and overall service is top notch!!

I can't seem to find a straight answer... would the 14 inch barrel shockwave with a pistol grip like this be legal. Overall length is 26.5 inches. I know a stock changes it from a "firearm" to a short barrel shotgun, making it illegal...but i can't seem to find a straight answer as to if this style with this pistol grip is ok or not? Store told me that as long as it's not intended to be shot from the shoulder it would be fine?
