is this copper oxidation in my can? is it harmful to the can?

was LARPing in my dads basement and noticed this can’s rocksett let lose from the adapter so I unscrewed it fully to see this. I googled before posting - as to not be that asshole - and it looks to me like copper oxidizing which makes sense. my real question is should I just let it go and shoot it or will the oxidation damage the actual van?

Slowing down a Fightlite upper?

Anybody had luck slowing down rate of fire on a Fightlite upper? It's a bit fast for my tastes. I like to be around 600-700 rpm.

Full disclosure not really NFA, lower has a super safety, but figured somebody in here might have the answer.

DA Wolfman - To wipe or not to wipe?

I am an absolute noob when it comes to suppressors. I just got my first can, a Dead Air Wolfman. I've decided against using wipes except for maybe the free one they sent me. Dead Air reccomends using the wipe retainer even if no wipe is used but also says you can remove it but grease the wipe cap threads to reduce carbon build up. Am I foolish to just leave it out all together? Would I receive a tiny reduction in sound by installing the retainer without a wipe simply because there is more "stuff" in my can? Apologies for my ingnorance.

Refund out of the blue

Anyone else recieve a refund out of the blue? Years ago, had to have been 6+ now, I submitted a form 1 for a can and a form 1 for an SBR. Or we'll I thought I submitted the one for the SBR. Aparrently I somehow didn't submit it despite paying for it. Never really worried about it and forgot about it. Tonight I received an email from eforms.notifications@atf about a refund asking to call to give them info for the refund. It just seems so strange to me. The email even says "draft application deleted after 90 days", but the only thing they could be refunding is from thousands of days ago at this point.

I figure I'll give them a call tomorrow and see what's up. If nothing else it's frees up $200 for the Oculus I was looking at the other day.

SilencerCo Velos 556K/Plan B

I know I can’t be the only one looking at this option: I have a 14.5” that will obviously require a 2.15-2.25” muzzle device. All the Charlie to Plan B adapters I’ve found do not work with the longer (2”+) muzzle devices for the Velos. SilencerCo said the depth of the first baffle is 1.55”.

Is there an option out there for a slightly longer Charlie to Plan B adapter to be able to use on a 14.5” with ~2.25” muzzle device?

dead airs redemption arc?

New Lazarus finally came in from capitol armory. I know people love to hate dead air but I’m pretty excited to hit the range to try this one out. Just in hand it feels like a tank but I’m really curious to see the lbp capabilities and how they compare to my hux. If anyone has any experience feel free to let me know your thoughts on it.

Form 1 SBR lower without having upper.

I just received my LWRC complete lower which I am planning on building into a SBR with multiple different uppers. My issue is I currently don’t have any of the uppers as I am still waiting for in stock notifications. The main upper for this build will be a 8 to 9in 300blk, but I am also building a dedicated 9in 22lr upper as well, other cartridges will be later down the road. However, as far as filing my eForm 1, I’m not sure how to fill it out as far as the overall length and barrel length, as I currently am not sure exactly what they will be as it will depend on what barrel comes in stock first. I am also unsure if I will be going to an A5 buffer system which will change the OAL. Do I more or less have to have everything on hand before I submit? Or is it ok to estimate these things? It’s my understanding that I can shorten or lengthen the rifle after it is approved, so I’m not sure how important exact numbers are when first submitting.

Any input or suggestions?

Thanks.

Rearden MFG heard my cry

Got the Charlie Atlas mount in today. After getting the Atlas for my Polo 30, I never wanted to touch a collar lock again and they came through with the clutch. Now I can mount both my Polo 30 or Omega36M using .375 pitch muzzle device without having to change brake or mount. Also it shortened the over all length and weight of my 36M. Win Win. Rearden MFG 🐐🫡🇺🇲. P.S. My 36M has been through the trenches, needs to get re-coated asap 😂.

Yhm mount

Does anyone happen to know if a yhm fat cat would fit this? I’m assuming I just need a bravo mount for it but we all know what happens when we assume. I’m still learning all the different types of mounts so I appreciate any help! Thanks

Help me choose a suppressor for my Sig Rattler Canebrake

I’ve been in this sub searching for a few days. I was initially going to get a Flow 762 Ti or Ventum but after reading through here, people advised against a flow thru can for a 5.5” rattler due the cycling issues. I think I’ve narrowed down my choices to either a trash panda or a nomad 30. Which one would you choose? It would’ve been nice to mitigate the gassy nature of a canebrake but I would choose sound suppression for a 300blk subsonic over the gas issue. It’s long shot but does anyone have a video of an Sig Rattler 5.5” with a Nomad 30 vs a Trash Panda? Thanks.

Excited for stamp day

Every stamp day feels like the first one. 7 day approval is a hell of a lot nicer compared to 9 months. Tossing this on my 10.3 to be more healthy

CAT Street Crack - First Impressions

Just certified yesterday, went to the range today to give her a whirl, specifically compared to the Omega 9k. I ran 124gr, 147gr, and 165gr 9mm through my FN509t and Glock 17 Gen 4. I am NOT a great pistol shooter; so, take that FWIW. I can’t say how the CAT SC functions for drills, etc., but it was pretty light on the end of the barrel for me as someone who primarily shoots rifles.

In the short config, it sounded about the same to me as the Omega 9k. It’s maybe 3/8” longer than the Omega, but it feels lighter (didn’t weigh it). My buddy had the same impression: the CAT SC felt easier to control. In the past, I have gotten a lot of particulate blowback from the Omega 9k on my FN509t. I didn’t notice any from the short config, and that can be ammo and host dependent. For example, my Glock is way more forgiving.

In the long config, CAT SC is amazing. I could actually hear and feel the difference between 147gr and 165gr. In short config or with the Omega 9k, all I could tell was supers vs subs. There IS a decent amount of gas blowback in long config, and I got a little blowback particulate but hardly noticeable. Less noticeable than with the Omega 9k.

SC gets hot fairly quickly but also cools down quickly. I haven’t disassembled the booster, but like all pistol cans I have used, I needed to retighten every mag or so. Switching between short and long is easy to do, and for those looking for the next drop, I would personally recommend the long config unless you just want/need the smaller form factor. You can hear the difference between short and long, and I think it’s enough to keep in long config. Modular is nice, but I wonder if the long config fixed is even quieter… 🤔

Another win for CAT. SC joins my ODB, SR, and MOB. Almost bought a WB today, but I want to stay married.

Bolt Action .308 Silencer Recommendation

I picked up this rifle today in .308 and currently have a Huxwrx QD762 for my AR-10 and Huxwrx Ventum 7.62 for my KS47. Neither of these silencers would be ideal for this rifle I feel. My gut tells me a traditional baffle stack type of silencer would work best.

Fast forward....

I really want to support OCL and thinking a traditional stack silencer would be better leads me to believe I should get a Polonium 30.

Any reason I shouldn't or better recommendation for around that price point?
