Form 1 Suppressor kits

Has anyone tried, or heard whether or not the JK armament kits are any good? They cost more but they’re modular. I can’t seem to find any decent reviews on the rimfire kits.

I know nothing about JK.
I have two of the modular Rebel Silencer brand suppressors. They are quiet enough, but the first round pop is quite noticeable. I now see it as more of a gimmick than an advantage, as I have never decided to make either of them shorter. Cleaning might be a little easier.

I'm not exactly trying to talk you out of anything, my experiences with a different brand may not even be relevant. I, personally, would pass in favor of a more traditional design.

By all means talk me out of/into something. I’m new at the surpressor game and any and all feed back is welcome.

I think it comes down to price and the 1.3" outside diameter of the tube. When you add in the thread adapter, drill jig, and extra cone the price is right up there. A 1.3" OD tube is pretty large compared to the usual 1" .22 rimfire suppressors. It may or may not start to occlude your site picture on pistols but shouldn't be a problem on rifles.

I just realized that my quietest .22LR suppressor, the Osprey Micro, is also modular and I've never had any desire to shorten it. It stays on a 22/45 Lite and works fine as-is on that pistol.
If you think you will actually want to make your suppressor shorter take a look at the $450 SilenerCo switchback and compare it to the JK system before making a decision. Bowers and Hughes make super short rimfire suppressors that I think have pretty reasonable reviews, so maybe there is something to making them shorter.

Here is a test on my 5.56 Form 1 suppressor. Kit is: 7.6" titanium tube from SD Tactical with titanium end cap and direct thread adapter. Internals are 50 degree stainless super duper cones from Pure Performance Armory.

This is the other Form 1 suppressor I did specifically for my 300 Blackout AR pistol. Barrel is an 8" Ballistic Advantage barrel with SD Tactical muzzle brake. Kit is a 6" carbon steel tube, end cap and muzzle brake adapter. Internals are also 50 degree stainless cones from Pure Performance Armory.

Wow, that is quiet. Less decibels than your voice?

The second video does not come through for me, says age restricted (and I am only 8 ;)

Cameras equalize sound, so it will bring the voice up to the level of the can on the play back. It would still sound impressively quiet in person though. Cameras just can't really capture the sound.

Same thing here. The action and wind sound as loud as the reports

That's not a form 1 can though, so ignore that part.

Are there differences in performance between form 1 and form X suppressors? I thought that it was just whether you buy a suppressor directly (form 1), or in a "trust?" (form X?)
