DIY suppressor

[oldhunter1954]

Just curious if anyone has played with JK Armament’s rifle Modular Solvent Trap (MST) kit. This kit allows you to create your own suppressor. I am aware that you need to do a Form 1 and get a tax stamp, etc before building anything. More interested if anyone has tried to build their own rifle suppressor. I have heard the Online Form 1 transactions are being processed way sooner than Form 4 transactions.

Haven’t used one but looks to be a solid design. Are they in stock anywhere?

[oldhunter1954]

Silencershop said they would have them very soon. I am on the email list.

I've been looking into DIY kits as well to save time waiting and a little $$$. These look like they have a great design but purportedly costs $500 and is made from aluminum. I've heard random people say don't buy aluminum cans unless it's for pistol rounds.

i have friends with aluminum cans and they work just fine im also in the middle of building mine and about to put in for another stamp as well , what u dont want is aluminum baffles. what u can do is use a Ti or stainless front 1 or 2 baffles and the rest aluminum if u want to save weight
i also dont suggest an aluminum cap on the threaded end they dont hold up well but fine on the other end

This is of interest to me, so who has the most effective best design?

i just put in for a second form 1 this one will be an 1.5x8 can , soon as my tube comes back from engraving on my first form1 ill do a build thread on that one as well its a 2x10 can

my first stamp was done in 37 days should be about the same on this next one , its well over a year for a form 4

That makes absolutely no sense at all. They make someone wait for a year that shells out 6-1300 for a suppressor, but 40 days for someone that makes their own? I can't imagine they do anything different background check wise for one vs the other. WTF?!

I have built several Form 1 cans they easily work as good or better than my cans made by other companies. I have a 1.5x7 Ti can with an ASR mount for my AR Grendel it shoots better than my Harvester does.

I think there are far better options then a JK MST. I have heard they do not hold up very well shooting supers out of a rifle.

So, anylinks to the better build ones or names of said ones? This sounds very interesting and I just might try this! Been looking at tbac newer ones butlong wait just trying to get one before the form 4 wait!

Avoid aluminum suppressors. You're buying something that will be with you a lifetime. That said, I've built two form 1 cans so far and my advice is also avoid them in totality. It's a fun project but not at all worth it in the end. Factory suppressors have come down so very far in price that Form 1's just aren't as good an investment. In the end you will have a non welded can that you've built for usually more money invested than say a YHM Resonator R2. In the end a form 1 rifle can will run you in the neighborhood of 5-600 dollars and that money would be better spent on an actual well made tuned can.

Here is a picture from AR15.com of that suppressor with what they claim as 8 mags of 5.56 run through it. Pretty eroded already. If you're set on the modular form 1 route, look at the hanshon brothers can the Quell Tech Mod-u-less (at least it's fully titanium). The main downfall there being it is only a 1" OD can rather than the standard 1.5" that most are these days.

If built correctly a form 1 can will last as long as a factory built can. Mine is all 17-4 including the tube which I bored a piece of 17-4 bar stock and made my tube. Go to a form1supressor board if you want good info on the how to’s and best suppliers of cones or radials. My cousin built himself one with aegis radials and it’s as good as any commercial can I’ve heard. Don’t go aluminum for a can shooting supers. I have probably 800-1000 rds of Grendel and 4-500 5.56 along with couple hundred 260 AI and creeds through mine and no erosion of my blast baffle as of yet. Do some research, it’s worth it

ETA: you can run all aluminum if used only for slow fire hunting. Rapid fire heat on aluminum is when you’ll start seeing erosion. Threaded cans are fine as long as your caps are secured with rocksett. Like mentioned above, a couple 17-4 baffles followed by aluminum would be better than all aluminum. Even better is 17-4 followed by TI, and best would be all 17-4.

I guess I should have prefaced my post with something to the affect of "if you have a lathe and are competent with turning/threading/machining then you can make a form 1 suppressor for a fraction of a factory can". As Mel and ricsmall show, if you have that kind of access then by all means go for it. If you are getting into a form 1 to shortcut the wait time and thinking you'll only have to drill some holes, then it's best to save your money and buy a factory can. If you're buying the parts, assembling it, drilling holes, and clipping baffles, expect to spend 500+ on a form 1 can (including the stamp) that is of much quality.

i only used the lathe to drill my baffles other then that i bought everything else , when i do another one only change ill make is a ti tube instead of an al tube
if i wanted to i could have machined every piece on my own , but it would have cost more then buying the parts sepreatly once i factor in my time

What components did you use that only cost $125 total? I'd get back into it at that price

I have 7 cans my favorites are the Form 1s and they are just as good or better than my factory cans. I use a Harvester 300 and a Form1 1.5 x 8 inch can on my 6.5's and my homemade one is just slightly more accurate.
Cost.
Harvester $750
Titanium can $450

All of my factory cans cost more and took upwards of 11 months to get my forms back. My Form1 builds on average took 4 weeks from submission of a Form 1 to taking it out shooting. One can was done with just a hand drill the rest with a mill and or a lathe. I have seen and heard of people building very successful cans with just drills and dremils.

my buddy is one that talked me into doing one by bringing one of his cans over for me to try to compare to an oem can
