    Form 1 Suppressors

    Got my Form 1s back today, 6/22 for a 9mm can and 7/28 for an integral .300 BLK.

    Time to get to work!

    Here's the endcap and modded booster for the 9mm

    Did you use a kit? Or make them yourself?

    Form 1 Suppressors

    I'm making the baffles myself. The booster is a Liberty Mystic that's had the threads moved back 3/8" and the OD turned down to 1.25". Place called Diversified Machine did that and the endcap for me. Ive got a buddy with a lathe that's helping thread the tube which is a piece of 2024 I got off of onlinemetals.

    The .300 I'm doing most of the work myself. I'll have the tube turned down to fit inside a Geissele barrel nut on the back end. I'm building a custom two piece gas block. I'll port the barrel right behind the threads. The endcap will be held in place by the muzzle device. There won't be any baffles, just a reflex style blast baffle integral to the gun. Probably going to use a Griffin minimalist on the muzzle to attach another Form 1 can. It'll be a three stamp build when I'm done. Already have the SBR stamp approved.

    Look forward to seeing your results after some range time. I think a Form 1 Suppressor would be a fun/great project to do. The Kit prices I've seen are very reasonable.

    I agree. Considering some of the new stuff offered by companies like SDTA (I think I got that right), will allow the use of muzzle devices by Griffin, YHM, etc, and not just thread on options (not that I have an issue with that) makes it so much easier nowadays....a friend just built a brake mounted SS & Ti .30 cal can in the low $200 range WITH parts left over for another one (parts not yet considered silencer parts)....

    It makes me want to build a few, to say the least. I'd like to start with making my own .22 can and then a lightweight .30 can for hunting

    SDTA no longer offers any brake adapters other than their own. Diversified Machine does Griffin, YHM, and 3 lug. He only takes custom orders and has a long lead time though, the quality is worth it in my opinion. There are a few other shops doing custom work as well, I just haven't dealt with them. Your budget and imagination are pretty much the only limitations when it comes to Form 1 cans. If you want a sub $100 can, you can build it, it'll be heavy and maybe not the most effective, but it will work. If you want to spend a grand on a can, you can do that to. Realistically though, you can do a can that's compares favorably to commercial cans for about $200-300 or so. Inconel and Stellite are the only metals that aren't as readily available for Form 1 builders. You can still get them, they're just prohibitively expensive. Grade 5 Ti, 17-4 SS, 7075 AL, etc. are all readily available for decent prices.

    Very cool. Have any CAD exports showing the general design? Really interested to see that .300 BLK integral build.

    Thanks for updating the info.

    There's a member on ARFcom suppressor forum/moderator (Big Waylon) and he's also active on Carolina Shooter's Club who is a WEALTH of info for form 1 cans...he's built I think 6-7 of them with a variety of machined adapters to work with YHM mounts, SiCo ASR (Spec War) mounts and I think some others (3 lug maybe). If anyone is interested in a Form1, stalk him on ARFcom.

    I wish, me and CAD software don't get along very well
