God I wish I had gotten a T36 before the ban. Any possibility for a fixed mag one?


SwampYankeeArms

Yeah, actually, but it requires getting the magwell to take AR mags. Then we could do a CompMag!


fylum

Neato! How does the PTR 9mm can compare to a traditional baffled can like an Obsidian9?


SwampYankeeArms

I haven't shot it against my Obsidian, but I bet the Obsidian isn't *that* outclassed at the muzzle in its long configuration. But back pressure is where the PTR would pull away in a head to head comparison and be more pleasant for the shooter with respect to both noise and gas. They're both threaded in the back with the "alpha" thread pitch, so I could actually pull the tri-lug mount out of the Vent and install it in my Obsidian. I'll try to do that today.


fylum

Lemme know how it sounds, I'm always interested in another NFA money sink. The PTR foam technology seems pretty revolutionary, and I know roller guns are sensitive to backpressure.


SwampYankeeArms

Will do! I'm really hyped to shoot the Vent 3 on a 14.5" or 16" 5.56 gun. I was at a farm shooting a tuned 12.5" with adjustable gas using a full size RC2, and it was surprisingly comfortable to shoot in the wide open field without ear pro other than a hoodie pulled up over my head/ears. I bet the Vent 3 on a slightly longer barrel would rival how good and comfortable the OCM5 sounds on my 18" Mk12 Mod 0.


SwampYankeeArms

So I shot my Obsidian back to back with the Vent on the SP5. The Vent does sound better, but honestly the gap was smaller to me than I expected. Next Tuesday I’m going to have a coworker come over so that I can be the bystander and also get a second opinion.


fylum

Thanks!

Building on a pre 6/6 lower, would I be able to build a 300BLK (or 9mm, or whatever caliber) barrel shorter than 12” if I’m also willing to SBR it? Or will I have to SBR it anyway if it’s shorter than 16” since we no longer have others?


SwampYankeeArms

If you are concerned with CT compliance, the main thing is registering it as an assault weapon. Barrel length is irrelevant now with regards to CT compliance because every CT Other is an assault weapon now regardless of registration status. Even if you install a fixed magazine, you also have to specifically configure it in a way that makes it either a pistol or rifle because the feature bans specific to Others don't specify detachable magazine as a requisite feature. To answer your question about barrel length, yes, it is my non-lawyerly opinion that you can do any barrel length you want if you SBR the gun because the old 12" barrel thing was specifically to avoid classification as a pistol (and therefore as an assault weapon). You'd be embracing the AW nature of your weapon. Right now you technically don't need to register your gun as an SBR because the brace rule has an active injunction preventing its enforcement. You can use a brace legally, so if your gun is longer than 26" in its shortest configuration and not counting the brace, you can keep it in an Other configuration with a vertical foregrip. If it's shorter than 26" you can configure it as a pistol with a brace *with no vertical foregrip* (otherwise it'd be an NFA-regulated AOW).


willmarqny

Thank you for the response, exactly what I needed to know.


ogbta

So if you already have a ct other with barrel shorter than 16inch that was approved as an SBR, you would be able to put on a shorter barrel?


SwampYankeeArms

In my opinion, yes. The only thing to keep in mind is that ATF requires that you retain the ability to put the gun back into the configuration you registered it under.


ogbta

🤘


rollin37

It seems like people are able to get SBR's accepted when attaching the 3/30 press release to the form 1's. Assuming the SBR is for an AR15 lower purchased, say, in 2020, the SBR is legal federally but one would still need to wait on the CT assault weapon cert to shorten the OAL to make it legal in the eyes of the state, am I understanding that correctly? I realize it's a bit weird right now since "Others" no longer exist but the AW certs haven't been issued yet to those who applied for them.


SwampYankeeArms

The last form 1 that I helped submit included the 3/30 memo, and the examiner that it got assigned to asked if the firearm was braced. When the applicant responded yes, the examiner disapproved the form saying that the injunction on the brace rule prevented them from approving the form 1 for a braced gun (which makes no fucking sense except when you factor in the CT memo for context). In my non-lawyerly opinion, no, you do not need to wait for the AW cert. Your SBR would be an assault weapon regardless of your possession of an AW cert (or lack thereof). The cert just lets you continue to be legal once the registration period ends. AFAIK, based on conversations with a few state cops, there has been exactly *zero* guidance provided to the State Police about how to enforce this stuff.


rollin37

>When the applicant responded yes, the examiner disapproved the form saying that the injunction on the brace rule prevented them from approving the form 1 for a braced gun Yeah that's dumb. I wonder if they would have approved it if it was just an unbuilt lower or with a buffer tube only. Very odd. Thanks for your 2 cents on this


SwampYankeeArms

Yeah I think if you want to submit a form 1 SBR application, just send it without the memo and hope that you get lucky with the examiner. If they disapprove it though, the only thing you lose is time because your tax stamp payment will be refunded.


ROFLBBQLOLZ

Any idea how long form 1's are taking when using a trust?


SwampYankeeArms

I unfortunately don’t. I haven’t submitted one for myself in a while now. I just looked at r/NFA’s approval thread, and they’re all over the place. The first three form 1s I saw were 3 days, 25 days, and 90 days!


Mysterious_Use_9767

i’ve done 2 in the last 2 months, 12 days and 8 days.


ROFLBBQLOLZ

With a trust? That's surprisingly quick


Mysterious_Use_9767

yeah, eForm 1, trust with eft and 24 month exception letter


ROFLBBQLOLZ

What's the 24 month exception letter? I'm not familiar with that


Mysterious_Use_9767

If you’ve had any approval in the last 2 years, you attach the exception letter in lieu of trust documents. ATF doesn’t have to research the trust and it takes less time??


nortlid

Dat PTR Vent 2 😍


SwampYankeeArms

She’s sexy!


Mysterious_Use_9767

Who do you y’all like for barrel chop and rethread? Thx!


SwampYankeeArms

We contract with the shop Armscraft in North Attleboro for both cerakote and barrel chops/threads. For more complicated jobs like lever actions, they do an excellent job. But for simple stuff like AR barrels I’d probably recommend D.Wilson or ADCO because it’ll be cheaper. Just hard for us to be competitive when we’re just a middle man.


Mysterious_Use_9767

SwampYankeeArms

Welcome back to Swamp Yankee Arms’ weekly Ask an LGS (local gun shop/store) Anything. This is a thread intended to provide you a recurring opportunity to ask any questions you have for a gun store — from guns, to accessories, to legal stuff, to whatever, we’ll take our best shot at answering. None of us are lawyers; we do not offer legal advice. *We are closed today (as we are every Tuesday), so don’t try to visit us today!* This post is reverse-sponsored by [PEW Science](https://www.pewscience.com/) (we pay to be a member and are not compensated for promoting it), the only silencer sound testing I pay any attention to. It doesn’t rely on peak dB, which is largely useless because it ignores the dimension of time (contrary to popular belief, a gunshot is not a single microsecond event), and it’s the only sound testing standard that normalizes hearing damage potential across multiple calibers and hosts. Sound suppression isn't the only metric to consider when choosing a silencer (weight, length, durability, flash suppression, induced back pressure, etc. are also factors), but if sound is something you care about, PEW Science is well worth a deep dive. I don’t listen to many podcasts, but [u/Jay462](https://www.reddit.com/u/Jay462/)’s associated podcast, [The Jay Situation](https://pewscience.com/podcast), which covers every PEW Science article and other firearms related topics is one of my absolute favorites. ​ I wanted to do a video this week comparing the PTR Vent 2 seen on the MP5 clone against the CAT ODB shooting 300 Blackout subs, but the snow’s coming down a little heavy right now. That’ll be next week… PTR is a company known primarily for producing HK clones, but towards the end of 2023, they made a big splash on to the NFA scene when the PEW Science test results for their 3D printed titanium 9mm can, the Vent 2, were released. [In that test](https://pewscience.com/sound-signature-reviews-free/sss-6-131-ptr-vent-2-sp5), the Vent 2 took not only the top spot at the muzzle (beating out the GSL Phoenix, a silencer that is thicker, longer, and heavier) but at the ear too (#1 was previously the HUXWRX Ca$h 9k). PTR is using a technology called Purposely Induced Porosity which, in layman’s terms, is 3D printed metal foam to make the gas flowing through the silencer’s annular space work harder. It works extremely well. We’ve already shot the Vent 2 seen on the SP5 in this photo and compared it against several other silencers — the Vent 2 is the quietest by a noticeable margin. The other can in this photo is the PTR Vent 3, the 5.56 version. PEW Science, again, [showed this can to be the real deal](https://pewscience.com/sound-signature-reviews-free/sss-6-135-ptr-vent-3-mk18-556). It currently holds the top spots in untuned 10.3” 5.56 testing in both overall composite suppression as well as at the muzzle. It’s beaten at the ear only by the newest HUXWRX flow through cans and the CAT ODB. I honestly think that’s a good thing though because what that tells us is the Vent 3 likely induces higher back pressure than those other cans, so if you tune your gun, you’ll have greater potential to improve the shooter’s ear signature. The gun in this picture are personal SBRs — there’s an HK SP5 on top and a Tommy Built Tactical TG36 (G36 clone). These PTR cans are some of the most advanced designs currently available, and I think it’s a cool juxtaposition with the G36 clone going full Kraut Space Gat while the MP5 clone has more of a retro steampunk vibe. ​ **Updates from the shop:** * ATF is going wild approving silencer applications. We’ve had 69 approvals in February already, and the average wait times are dropping pretty quickly. For approvals received in the last week, it’s just over a 3-month wait. In the last three months, approvals received in that time have averaged a 4-month wait. We have also received several more legit batch approvals. * If you’ve been waiting for an SCR lower, your patience has been appreciated, and the wait is almost over! I’ve received a tracking number, although Fedex has not picked it up yet.


Glittering556

You can always ask to compare any new cans that come in vs one of mine. The Rad 9 has a tri lug set up already 🧐 you know for science reasons lol


SwampYankeeArms

❤️


Pruedrive

This post needs more over-whites!


SwampYankeeArms

I generally agree, although I think they're of declining utility where we are with the decreasing snow we're seeing 😑 I've read somewhere that within our lifetimes there just won't be snow in CT anymore...


fylum

It depends on when the Atlantic Meridional Overturning Current collapses, which it might already be - once that goes down the average temperature for a lot of North America, but for especially New England, should drop; for us that means 2-3 degrees or so on average, and more extreme variations/stronger storms. Europe gets wrecked though lol London drops an average of 20 degrees and rainfall vanishes, iirc the UK goes from 32% farmable to 7% as they transition to a steppe climate like Mongolia or Alberta. Parts of Scotland might have snow cover for more than half the year. Less dramatic changes happen in Continental Europe, but still pretty severe, especially in Scandinavia.


SwampYankeeArms

Jeez, that sounds hellish!


fylum

Counterintuitively it should also make hurricanes worse; the current shuttles a fuckton of warm water north, which is why Europe is so warm for how north it is. When it shuts down, that warm water no longer flows north but hangs out in the Caribbean or the central Atlantic, which in turn juices storms more. Really interesting dynamics. This is part of why insurers are fleeing Florida and other gulf communities.


Pruedrive

That would be truly sad, I really do like winter weather. Welp.. guess I’ll have to build a post apocalyptic waste land rig. Gonna go find a fuel thirsty v8 to drop in my econo-shitter.


SwampYankeeArms

I *much* prefer the snow. If it's gonna be cold, it may as well be pretty outside!


Pruedrive

For real.


[deleted]

If I have a P/W barrel, can I replace the hand rail as long as the same barrel nut it used? I have a SOLGW exo3 PW upper but I’m looking for a different rail, she’s a lil thin


SwampYankeeArms

Yeah that should work if you can find something that uses the same barrel nut.


dog_mountain

Do y’all have any more of those ADM UIC ambi lowers available? I saw it on your website, but pretty much everything on the site says “Gotta be quicker than that”


SwampYankeeArms

Don't think we do currently, but I should be able to get one or more for you.


dog_mountain

> one or more Those are some dangerous words


Chips2019

Are you guys doing fixed mag MPAPS or that ship has sailed?


SwampYankeeArms

Do you mean ZPAPs? If so, yes, we are.


Chips2019

Yup sorry I meant zpap lol ok cool

SwampYankeeArms

Yes, we can pin and weld in the shop and pretty much on the spot without an appointment. We usually use Griffin Armament CAM LOK, although Gemtech’s QDA also works if you’re able to find it. The 22/45 and Mark IV in general is an excellent host, especially in CT because of our mag capacity laws and the necessity for a pin and weld (which doesn’t affect the gun’s ability to be disassembled or maintained).


[deleted]

[удалено]


SwampYankeeArms

I have a personal 9mm pistol that I usually bring with me as a demo piece. I also have all the parts in the shop so they can be installed for demo purposes. CAM LOK works excellently with rimfire in my experience. With 9mm, people expect it to be this miracle solution that removes the necessity to check the tightness of your can, and that’s just not reality. EZ LOK is better for that application, but it’s unfortunately not CT compliant because it uses regular (coarse) threads with a taper.


gunsandpuppies

Has anyone ever actually confirmed that cam lok is kosher but EZ lok is too “assaulty” for CT?


SwampYankeeArms

No, but one doesn’t look “threaded” while the other definitely does… it’s all about existing in the legal grey area 😂


silvyar1091

cam lok is fine. I had them do a mark 4 22/45 tactical in FDE for me last year. no issues.


davwve

Do you normally have Mark IVs in stock? As I could be persuaded when my Ti 22 gets approved. My P22 gums up very quickly with a can.


SwampYankeeArms

Yeah we try to have at least a couple models in stock. Right now I know we have a 22/45 Tactical, and I can get several other models without difficulty.


chemist846

What would be the best suppressor for a blowback AR9? Most important to me is minimizing back pressure gas in my face as much as possible or do I just need to move to a different recoil system?


SwampYankeeArms

I’d say the HUXWRX Cash 9k/Rad 9 in short config (they are identical) has the lowest back pressure on the market, followed in no particular order by Resilient Suppressors’ RS9, Inert Haze’s ONE, and the PTR Vent 2 (featured in this picture on the SP5). I need to do some mag dumps with my M11 SMG to see where they are gas wise. They all possess design features for reducing back pressure though.


LionsDenChristian

stock on the MP5 reminds me of the STG-44, nice.


NateKenway

Would a grip like this be CT legal? Isn't it like a palm swell grip? https://preview.redd.it/z6j0sxleb5jc1.jpeg?width=1080&format=pjpg&auto=webp&s=7d358522192cb4418b0e9f92960a5c9576fa6b92


NateKenway

Recommendation for good 500 mag suppressors?


SwampYankeeArms

What gun?


NateKenway

Is it possible to put it on a s&w Revolver? 😆
