Form 1 builder.com

Yes, it can be legal to make a silencer. For everything Form-1, from silencer designs that are easily made, to filing forms with the BATF, to 3D modeling. Remember, you must have an approved BATF Form-1 to make a silencer. All NFA laws apply.

Hey everyone I’m big into thermal hog hunting and and I’m applying for a form 1 to make a can. What do y’all have to say about form1builder.com? Good bad? The solvent trap kit looks great for my budget. I’ll apply for form 1 get approved then order the kit from form 1 builder but what’s your opinion on the site? thanks

All aluminum build wouldn't be what I would want for a possible high rate of fire can. Especially low grade 6061.

I could not comment on their service or quality but the variety of what they have to offer even with them being out of stock on about half their products is a lot more comprehensive than what you might find on Aliexpress. That said their prices are about 10 times as high. If you are hunting hogs with a .22LR or a 9mm carbine I would think their products would be able to satisfy your expectations. If you are using a .223 or anything in a high powered rifle I would not use anything I saw on their site. But, I am not any thing close to an expert on quality of high powered rifle cans.

I’m not sure what to think of them. What would y’all recommend as a form 1 suppressor? This is what I’m looking at, I’m shooting 6.5 grendel. Would it hold up? https://www.form1builder.com/wp-content ... RODUCT.jpg

I hunt hogs with an AR chambered in 6.8 spc.
Hard pass.
Titanium tube, 17-4 PH bast and second baffle, titanium for the rest

You will need a build that is adequate for a .223 or 5.56 AR15 or a 7.62x39 to compare with the Grendel. You might look for people with hands on experience with those. My reasoning is the Grendel is based on the 7.62x39 and has a similar energy capacity of about 1,400 foot pounds.

Places selling similar 10x2" cans often claim they are good for a .308 which has about twice the horsepower and I believe they are probably correct about the ability of their components to be crafted into something that can to take the sound down 25 or 30 dBA. How long will the suppressor hold up is a separate matter. You will find folks confident and those telling you the kit will not last 100 rounds. Look for someone that has hands on experience with a 2"x 10" 6061 Aluminum cone baffle setup on any of the above platforms. Short barrel rifles in the above would also be comparable or a bit harder on the can.

I can't really give you a definitive answer

Are you hunting hogs out past 150 yards?

Here is a red aluminum 1.75" x 10" that claims 7075 threaded end and 6061 everywhere else that ships from the USA for $33. I do not know if this is a good can. It does seem to be in the same spectrum as the one you are asking about. The vendor claims it is good for a 30 cal. they do not note if it is a 300 winmag or a 30/30. Big difference. https://www.aliexpress.com/item/4000110981980.html

I’ll be shooting most hogs about 50-60 yards then if I’m stretching it probably max about 150. I just want something a little quieter. I’m not sure what to buy once I get approved for the form 1.

Can an all Al can be used on 6.5 supers? Sure. It's up to you to use discretion w/ your fire schedule.
Do I know what grade Al (or to what Thk walls) these trap companies are using? No. This is important, especially w/ Al.

Make sure you look at the baffles geometry. Just because someone is selling a "Solvent Trap Kit", doesn't mean it's going to make a good suppressor.

I don't see what shooting distance has to do with this?

I've had some of those through. Recoring them into a durable, effective suppressor is a lot of work.

My opinion? Hard pass. They're really thick everywhere, so don't save any weight, and 6061 isn't an alloy I'd use for any part of a suppressor. If they were half the price and there were no tax stamp, I'd say give it a whirl. But to throw $500 at a kit + stamp and end up with something that doesn't perform well and can't handle any volume of fire? Spend a little more and build something much better.

Some folks consider the Grendel an 800 yard rifle. I don't really know about 800 but am confident it will do 500 within my ability to compensate for ballistics.
You want quiet you might consider shooting something sub-sonic as any high powered rifle is going to still be about as loud as a .22LR pistol if the rifle is suppressed and the pistol is not.
Put a decent can on a 9mm carbine shooting most 147 grain offerings and you can be as quiet as a pellet gun.
Most .22LR out of a rifle are supersonic so still have a supersonic crack. This will go away with a barrel short enough the projectile has not yet reached transonic speed when it exits the muzzle.
I have a 10/22 Charger pistol with a 4 1/2" barrel and most bulk ammo is subsonic from that. If that had a suppressor it could be as quiet as a medium hand clap.
For a bolt action you might look at a 300 blackout or even look for subsonic loading for your Grendel.

Realize if you decide to make a can for use with a high powered rifle shooting subsonic loads your durability and possibly safety will depend on you never getting ammo mixed up.

A decent home brewed can for .2LR or 9mm, could reasonably be in the 1.5x8" range or smaller clear down to 1x6" for .22LR. I would not recommend 1x6" but might do 1x8".

Ballistics on a .22LR or 9mm leaving the muzzle at 1,000 feet per second will drop a total of about 3" in the first 100 feet, less than 1' at 200 feet, about 2' at 100 yards, less than 4' at 400', less than 6' at 500' and less than 9' at 200 yards. your specific loads will determine results. I am able to reliably hit a 24" diameter target with the .22LR pistol described above at 200 yards. 3xscope.

May I ask why?
One of the quietest 22lr, muzzle threaded, designs I've done was right at 1"OD x 5.25"LG.

Because not everyone has your skills and abilities. If I were to hazard a guess I would categorize you as a detail oriented technologically sophisticated artist.

If I were to guess regarding the original poster I would not anticipate he has easy access to a lathe or the ability to fabricate close tolerance assemblies. I doubt more than a handful of machinists would consider purchasing the kit he noted for $300. Likewise, I assumed he wanted quiet enough to not disrupt conversation in and observation from a blind rather than needing movie quiet.

This was directed toward a first builder who was still anticipating a solvent trap component design. I did not think he was even going to consider shortening skirts and adding baffles from a second kit. I myself am awaiting my first form 1 and planning to use solvent trap components. Aluminum components for a .22LR direct thread design. I am willing to sacrifice 2" overall length to accomplish what I might have been able to do in less space with better components and closer tolerances.

Share your small design?

If I shot a .22 the hogs would laugh at me and 300 blackout I’ve already had one i shoot too far for that caliber. I want to shoot grendel but I just want to quiet it down a bit. What kind of tube would y’all recommend or a solvent trap kit? I’d get approved for form 1 first.

For a better source of vendor references check this forum:

https://form1suppressor.boards.net/thre ... dated-list

https://form1suppressor.boards.net/

Otherwise:

https://www.preppersdiscount.com/store/ ... ters_.html

There are a lot of offerings in metals other than 6061 Aluminum here. I can not say whether their products, prices, or customer service is good or bad as I do not know. I do not even know that 6061 Aluminum is no good. But I have heard a lot of folks advise to stay away from it for anything stronger than a .45ACP. Your rifle is about 3x as strong as a .45

It looks like the kits they sell are ala carte offerings. Meaning you will need to be sure you are getting all the components you want and not assume because you see an end cap and a tube that you are getting two end caps and one is threaded or that a stack of baffles is included.

As a less experienced builder you might want to look for a kit that has a little more overall volume than commercial offerings for the your cartridge. I would suggest 50% larger overall.

Looking at their cup offerings I did not see any with profiles that look like they would be much more efficient than freeze plugs. You would probably benefit from finding a source of 60 degree cone baffles, learning about clipped baffles, and about staggering your baffle skirt length.
