First Form 1 Design

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.

First Form 1 Design

Post by Dunkman » Tue Dec 31, 2019 10:32 am

I am designing my first Form 1 silencer and I would like some feedback or input. I have already purchased the radial cups so that is the direction I am heading. I do not have any other parts so the size could vary slightly, but this is as close to accurate as I can get for the time being. I was planning on machining a groove so all the clips line up, hence why the spacing is slightly less than the spacer size listed below. My first question is if I have enough clearance between baffles when I drop the spacing for the last three? I dropped the spacing to allow for another baffle. My next question is if my blast chamber is too large? I believe the distance the muzzle brake surpasses the ASR mount is correct. This is going to see 5.56/.223, 6.8 SPC, and 300 Blackout. What size do you recommend I ream the baffles and clip? Would anyone change anything?

I think it looks good.

I don't think you need the 2" spacer because the DM tube has that built in. Correct me if I am wrong there. Never bought an ASR tube.

.375" bore (or even slightly smaller) should cover all of your bases.

Single clips, aligned, and you've got a SiCo Saker ASR 762

I will probably buy the tube once I get my Form 1 approved, and see what spacer I need then.

I would be happy with Saker results for this can!

Any input on going to a radial coned end cap vs. the low profile one I initially planned on?

Coned endcap is supposed to cause more gas turbulence at the end of your can, which I guess should equate to better suppression.

How are things coming along?

All documents received by ATF, waiting on approval now. I went ahead and ordered materials from Diversified Machine 18 days ago and haven't had any contact from them since the initial email confirming my order. I've sent 3 emails for an order status to both of their email addresses and haven't heard a peep. Has anyone else had problems with them?

If the items you ordered were in stock at the time, just sit back and wait.

Yes, they were in stock. I may be a little impatient, but spending $200+ with someone and not getting a response can be eerie.

On other forums there are constant threads asking about DM lead times, not responding to emails etc. No question that they have good quality parts but their lack of customer service response is the norm it seems.

On another note, I've ordered some items from Maverick Precision recently and their communication has been stellar. Almost immediate order confirmation emails, shipping notices and tracking info provided without asking. In stock items shipping within 3-7 days and arriving 3 days priority mail packed well. I've had one item from them that the confirmation email got buried in spam and I emailed them after 5 days asking about order status. I had a reply back in 30 minutes assuring me my order was going out the same day.
