Form 1 can builds

[Poconnor]

Who has built one? I want to build a few..—22LR, .30 cal and 9mm. Looking to hear first hand experience

[snow white]

I was just about to start this exact thred. I want to know how form 1 cans stand up to factory cans. How tough are the form 1 cans?

[5pins]

Are you talking about making one out of one the "solvent trap kits" you see advertised?

[LittleLebowski]

It depends. Aluminum solvent trap from China? Quality steel or titanium tube from the US?

[snow white]

I would go with a quality American company.

I would also be looking at durability as my #1 priority for the can so steel would be the choice.

[Casual Friday]

I'm doing a form 1 can right now. Should I do a thread about it? I wasn't sure anyone would be interested.

I would be grateful for the information for shure.

I would be grateful for the information for shure.

Ok I'll start a thread in next day or so with a parts list and whatnot.

[SecondsCount]

I really want to do one for a 22LR but have a hard time paying that ridiculous $200 tax on something that would cost me $20 in materials to build :mad:

[5pins]

OK good no solvent traps. We get those kits in seized all the time and they are pure garbage.

There are several vendors who offer quality parts that you can build a form 1 can with. You can find tubes and other parts machined from titanium, stainless steel, and aluminum. These require some finishing work by the builder.

You can spend as much on these parts as buying a commercial can, or close to it. The biggest advantage to going this route right now is that ATF is approving form 1 submissions in as little as 30 days.

I recommend that anyone interested in doing this take a look at Form1suppresor.boards.net. There is a wealth of information available there.

I have a Form 1 rimfire can that I made using a Quiet Bore kit. The tube is aluminum and baffles are titanium.

I think Form 1 cans are great for rimfire. You end up with the same materials and construction method that the commercial offerings use, but with a 4 week wait and usually less cost. All in my kit was $250 including the jig and bit to drill the cups and end cap. It took 20 days for my Form 1 to be approved last fall.

When you get up to center-fire cans I think you give up a lot. The newer sleeveless designs from Q, YHM, Dead Air, etc are much lighter with more internal volume. Even with a sleeved if you weld the baffle stack together you can use a thinner walled outer tube.

My YHM Turbo K was $300 on sale which is a friggen steal for how good it is. Every time I price out a Form 1 .30 call can using primarily titanium with a few 17-4 blast baffles it ends up being $600+ and heavier than I want. yHM Resonator is the same weight and cheaper while a Nomad Ti is a little more expensive and a lot lighter. Plus they have warranties.

This looks interesting.

There is a therad here on the form1suppressor.boards.net.

$205 to $240 plus tax stamp sounds like a decent deal.

I agree it is interesting. It's also 18 oz.

You could order a YHM Resonator, with a QD attachment, for $500 or less. It would be quieter, lighter, and have a warranty. And an inconnel blast baffle.

I still think Form 1 makes sense for pistol and rimfire cans, but you are giving up a lot compared to modern tubeless rifle cans.

[5pins]

So I can pay twice as much, wait for nine months to a year, if I can find it in stock, and save 1.2 oz in weight. Oh, and get a lifetime warranty I will probably never use.

I understand what you are saying but, $250+ more and wait for who knows how long are not great selling points.

On the other hand, I can order this and submit my form 1 now and probably have them both by mid next month. Not to mention it's more fun to do it yourself.


I'm thinking of making it dedicated to my 10.5 inch 5.56. Directly connect it to the barrel. I'm not sure if there is something out there that would do better for that price so I'm still looking around. Just thinking out loud right now.

I’m thinking about doing a Form 1 .22 rimfire suppressor build. I know absolutely nothing about the legitimate vendors who sell kits. Who offers the best ones?

Not a recommendation but an interesting video.

If the serial numbered tube on the outside of the can survived the abuse, he could replace the core, maintain the tube and still have an operable and legal suppressor.

I’d pay a lot more for this exact can in Ti. Anyone know where I can find one? $200 stamp plus a $200 kit would be a deal.

That is a very grey area. ATF had been clear that as an individual you cannot manufacture new components or repair your own can after completion.

OK. I will admit I’m not an expert. He is an SOT, and he manufactured the can to begin with. So I went with the assumption that the serialized part was undamaged, and he was replacing other parts. I viewed it like replacing an end cap, or using two end caps, one in 22lr, one in 9mm (as the manufacturer). Again I could be completely wrong.

Yes, as an SOT he can repair it.

I just submitted my form 1 and I'm going to use it for the kit I linked above. Well, not the whole kit just the tube and 7 cups. They don't have the adaptor I need so I'm going to make my own. And if I'm going to make the adaptor I may as well make the end cap also since I have 1/2 inch stainless bar stock.

After waiting for a little over 4 months the ATF finally gave me permission to drill.

This is the kit I got from Straight Six Tactical. I decided to get the complete kit with heat treatment instead of making an endcap and adapter. It came with the Griffin adapter so I decided to get it so I could use it on different rifles. While I was waiting for the ATF I test fitted and found out their adapter, unfortunately, only works with the short EZ brake which I was not going to use.

https://i.imgur.com/WpISzwAl.jpg

All the brakes I had were all too long and hit the first "cup". I ended up getting a Griffin Plan-A XL adapter giving me the extra space needed.
This brought up another issue. The Griffin adapter would not screw on the tube. It seemed that the threads on the tube were not cut deep enough. SST sent me a shipping label to sent it back so they could fix it but I decided to take care of it myself and after about 20 minutes of elbow grease and some lapping compound I was able to get it to fit.

Finally last week I was able to drill, assemble, and paint it with KG Kote. The first 30 rounds out of my 10.5 inch AR sounded great.

I had a chance to see how my can did with a Larson Davis LxT sound meter. I set it up one meter to the left of the muzzle. I'm not an expert but set it up as best as I could and think I got it right.

Unsuppressed I got a 10 shot average of 164.9 dB. With the suppressor on the 10 shot velocity was 139.1 dB. This is with a 10.5 inch AR using Federal .223 62gr soft points. The can was drilled out to .30 cal.

Next, I plan on trying a 16 inch AR in .223, and an 18 inch 6.5 Grendel. Then a 24 inch .308 bolt gun and a 26 inch .300 Win Mag.

[5pins]

I totally forgot to come back to this thread with some more readings.

With a 16-inch AR using .223 ammo I had a 10 shot unsuppressed reading of 163.7 dB and a 10 suppressed of 135.7. In my 6.5 Grendel the 10 shot unsuppressed was also 163.7 dB and a 10 shot suppressed of 135.7 dB.

From my Remington 700 .308 with a 24-inch barrel using Winchester 168gr match the 5 shot unsuppressed was 167.3 dB and a 5 shot suppressed of 138.6 dB.

And finally in my .300 Win Mag I had a 3 shot unsuppressed of 171.3 dB and a suppressed 3 shot of 143.3 dB.
