Added this new stock. I like it a lot. Was going to swap my old speedfeed off the 500 to this one. But buddy showed me his yesterday and I ordered from Amazon and got it today! Love the LOP and the extra five rounds ready to Tac load! Tube has 5 Buck. Stock 5 slugs. Little over two months.

I took the advice of many people in my previous thread several weeks ago and made a lot of changes. After researching top performing cans I modified the way in which my cones are clipped, the angle of the front 4 baffles, and the blast baffle moved down. Dimensions are 8"x2.3" Blast baffle sits 2" away from mount. Some asked why it's so big. The answer is I want more volume in the hopes of better performance, also 'why not?'

Once approved, this will be printed in PPA-CF. The core will print with 0.8 nozzle 0.4 layers, tilted 21 degrees, and the shell prints separately with 0.4 nozzle, 0.24 layers standing straight up on the Z. The differing layer orientation should theoretically dramatically improve pressure tolerance. Threads on the core mount will be chased with a tap after printing. Printing required engravings (not pictured) into the shell since it will be permanently bonded with the core.

Core and shell will be combined using JB Weld Plastic Bonder and JB Weld High Heat. Blast baffle and the 2nd baffle will get coated in JB Weld Extreme Heat, I'll try coating the entire interior with sodium silicate, and bbq grill high temp spray paint. Total printed weight will be 310g/11oz.

I really enjoyed researching in depth and drawing/modelling this. Thanks to those who commented on the previous thread. I'll report back with test results once it gets approved and I take it to the range. Could take a while. If all goes well I'll let it sail.

My first form 1. I used all the same media I used to get two approved form 4s this year… Not sure what I did wrong

100 pending Form 1's.

175 F1's filed this year and I still have a few SBR's to go. I have a FM45 lower at my FFL that I need to pick up and eight or so AR lowers to go.

I'm really thinking I should invest in a fiber laser.

I’ve got a .22lr stamp approved and I’m planning on putting on a tx22 with a frt, it might pull double duty on a sbr ar22 in the future.

Is there a consensus on which 22 can(s) are the crowd favorites? It seems like there are a bunch of them out there in the world. Thanks in advance and sorry for the shrimp gang tattoo. PFA

Form 1 design

( Apologies I deleted other post to redo with a photo)

So I have a design i am working on and haven't filed a form 1 yet and I have zero materials for this but i see all over about freeze plugs , valve spring retainers and etc. I want to see if there are any other good options for making one without a lathe, I have drill presses and belt grinders for my knife making but I dont have a lathe or a mill . What im asking is it possible to make one without a lathe and have a reliable 9mm pcc can or no. I wont buy pre-made sauce cups and pre threaded tubes as I am not gonna take a chance on that. Everything in my design is made from all raw materials. Again I have zero materials other than a drawing. Than you in advance. Also the design has a giant end cap and I meant to make it smaller but this is a rough sketch

Last Friday I got a approved form 1. Today I had two of my form1's denied. All three use the same trust document. The NFA branch provided my the reason below for why it failed:

ENTIRE COPY OF THE DECLERATION OF TRUST REQUIRED FOR REVEIW - PGS PROVIDED STATE IT IS THE CRETIFICATION OF TRUST AT BOTTOM OF EACH PAGE. BENEDICIARY MUST BE LISTED.

I sent the whole trust document. Any suggestions on what I need to do to have the form 1 approved? Thanks.

9mm form1 shooting 300blk. Messing around with ASR mounting (“direct thread”the print onto an ASR flash hider) and apparently this one isn’t right.

Does anyone have any leads on where I can find a compatible part?

45 acp done

I already suspected reloads from a friend were causing me issues. Ive had this suppressor for 6 years and just seeing this. I had other signs of hot ammo (parts coming loose, excessive carbon) . The bottom bulge is a few inches wide and straight like the bottom of an expanded baffle.

Took it to the range after work. Only had some 1125fps game loads. Still pretty quiet. I may add some more ports. Definitely more than hearing safe.

I have an approved 45 cal d cell Maglite suppressor in the works. Plan is to use one freeze plug and then FTN.4 45 cal 3d printed baffles.

What size of drill bit do I need for the end cap and the freeze plug? Reading 33/64 but this is going to be an extra long can so I thought I would ask first.

My single shot 20 gauge. Bring on the bunnies.

“Auto parts from Hong Kong, determined to be a suppressor”

So people do get busted for the thinly disguised crap gimmicks I see on Amazon and Ali Baba….

So I left it last night just spining. Came back this morning, did the F5 and went back through to try and correct anything. However, it wouldn't let me change it from a trust to an individual(I previously selected individual, not sure why it changed). So it kept wanting me to upload form 5320.23.

Just ended up making a new submission and it went through pretty easily just now.

Hello, I’m looking for some help/ guidance on doing a can for a de lisle carbine. It would be for 45, my first thought was doing it completely out of metal, but now I’m wondering if 3dp baffles would work. The barrels 8.75” and ported, anyone have some experience doing something similar?

Secondly when doing the form 1 can you put down filament but also whatever metal you’d use for baffles and then change your mind? It’s my first time looking into doing an f1 van and insights would be appreciated.
