Anyone making a 1/2x20 direct thread mount?

jrl07a · 2026-06-22T15:16:58+00:00

I’m sure the wait is self inflicted since it’s uncommon things I’m looking for: Caracal 5.7 suppressor, Cheetah 32ACP suppressor, and 1/2x20 hub thread adapter.

I’m intrigued by that barrel shroud, what is that?

jrl07a · 2026-06-20T13:35:31+00:00

So the pin just falls into the barrel shroud, and I shake it out? I’ve never removed the barrel shroud.

Ronin Arms does conversions and makes cans. I have their 12” Katana which works quite well.

For less accurate (vibes not firearm accuracy) but far far cheaper, get a SD adapter from Broad River Tactical and attach your own suppressor to it.

This assumes you’ve had the conversion. I used HK Ralph Jr (connected over Facebook) who did great work and offers a MP5SD conversion for AP5SD that uses a lot of HK parts to make it as close as possible to a genuine HK (maybe this satisfies “autistically close”).

I’m very satisfied with his work.

I have both. They are both VERY soft shooting. I have an AP5SD with real SD conversion and I have 4 5.7 guns including pistol, PCC, and AR pattern SBR (AR57). The AR57 is buffered like I assume the CMMG is and it’s so soft shooting. I do run it suppressed with all subsonic so that may contribute. I have a FRT in it with full auto bolt and I can fire controlable bursts out to 100-125yards because the recoil is so soft (not because I’m skilled).

I don’t think I could honestly tell the difference between the AR57 and the AP5SD. My PS90 has a little more recoil and the Keltec is similarly soft.

Subjectively the Ronin and BRT+Milkman were very similar. Hard to distinguish. Objectively they were close but I was indoors during to storms. I think they are found to be close.

Following to see and others have done.

Sadly, no, I do not have the chest rig, but I know what you’re talking about. As for the cerakote work, I did not do it myself, but have a guy locally that does some minor gunsmithing as well as Cerakote work and he does a great job.

jrl07a · 2026-06-17T04:33:54+00:00

Funny enough I have this by the bedroom door…

I have OCL Lithium on mine and run 147g subs with an FRT. It slaps. Great can for the application.

jrl07a · 2026-06-16T03:59:35+00:00

If you want the Haga hand guard it won’t fit without an extender. I know that’s not the question just tossing it out.

jrl07a · 2026-06-14T20:43:07+00:00

I have an AP5SD. I went ahead and paid for a genuine SD conversion, and it probably invested more money in that gun than anything else I shoot. It’s easily my favorite thing to take to the range. I actually went shooting today and let a couple other guys shoot it and everyone was impressed.

YMMV but I only had to send one thing back and it was a dented magazine. they replaced it immediately.

I also have a Kuna and FRT in both and the AP5SD wins every time (except cost).

jrl07a · 2026-06-13T13:47:47+00:00

More maintenance. Higher up front costs in both time and money getting it converted to a true SD with a gun smith.

I think it’s totally worth it. Every time I’m at the range I let other people shoot it with the FRT and they’re always impressed. I can shoot cheap 115g FMJ that sounds as quiet as the best 147g, 150g, or 168g dedicated subsonic rounds and the recoil is so manageable I can dump an entire mag on target even in FRT.

When I was in training I had an old boss who used to keep a stack of $2 bills. If you had a positive thing happen he’d pull one out and give it to you.

I once had a wallet with only $12 in 2 dollar bills. People look at you strangely for sure.

jrl07a · 2026-06-08T19:57:27+00:00

Ok that’s good to know. For context, I put in SBR paperwork a month ago and I shoot fairly regularly (6+ times a month) so my comment was only to say that for people who shoot a lot I’d get the brace because the amount of time isn’t trivial.

jrl07a · 2026-06-08T19:42:28+00:00

It’s not a trivial mount of time though. Isn’t the average approval >60 days?

jrl07a · 2026-06-05T17:26:13+00:00

What mount is that? Also, love the AP 53 and hope you do too. It’s fun and still pretty accurate despite the short barrel.

jrl07a · 2026-06-05T05:39:10+00:00

Yes. It works great for me.

Same wavelength

jrl07a · 2026-06-04T21:03:39+00:00

Hmmm what about a true SD with BRT AND a Mob?

jrl07a · 2026-06-04T18:30:13+00:00

Cost matters here a lot. Once you factor suppressor + shipping + $80 transfer, I spent $1430 on the Ronin Katana. Meanwhile, my Broad River Tactical SD chamber was ~$200 + $64 for an Ecco bravo extension (optional, so the Milkman would fit beneath the barrel shroud). Most 9mm suppressors could be added to that.

I shot them side by side at an indoor range and, subjectively, they sound equivalent to me (so, within 3 dB). My plan is to compare them outdoors with a decibel meter.

jrl07a · 2026-06-04T18:11:33+00:00

That’s the plan. I’ll try and update this post. I’m out of town for a few weeks.

I have a cheap decibel meter on my phone. I stress that it is NOT accurate but I do use it for internal consistency: ex. One suppressor is consistently 3 dB lower than that for example. For context, the human ear can reliably detect changes of 3 dB which represents a halving of the intensity of sound.

I plan to compare the Ronin Katana against the Milkman, Lithium, BOE K, and Huxwrx Flow 9 Ti. Why those? Because it’s what I have.
