    I think an MP18 would be a good candidate since the brake control is on the bottom of the action.

    Oh that’s neat! I was wondering what practical uses this had when tube magazines have existed for quite some time.

    Between this and the Pedersen device, there have been some fascinating modifications for firearms.

    I had a neat thought but not the effort to figure it out but could you build something like this for a paper cartridge gun?

    A well tuned Altdorf device is one of the most satisfying mechanical things for me to watch. I'd really like to see someone running a well-adjusted hard, like in a 3-gun match.

    Alof device. When pump actions first came this was an alternative for those who owned a single shot already

    I am kind of lining the tri-tone, but I’m not sold. Any suggestions for the color? Obsessed with the copper fx cerakote. I have an LFA Apollo on order with the same.

    Lever v2 SSA-E buffer removal hammer mod

    Originally posted by u/zemogwai at 2025-06-15T02:04:53Z

    Anybody know where I can find the hammer mod for the SSA-E trigger to eliminate the need for the 48mm buffer? S3igu2 was working on one but I dont think it ever got released

    Meatbanana (i think thats his name) has a hammer mod but I believe it requires modifying the hammer which I dont want to do.

    Any help is appreciated!

    MKII mags?

    Absolutely love shooting my Savage MKII.

    The 5 round magazine was infuriating. Bought a few 10 round mags and I’m not any less pissed off loading them every 30 seconds.

    Is there a know 20+ round solution already out there already?

    I’ve got a 3 pack of 33 round Glock mag springs and a 3rd grade understanding of Fusion. I’m willing to use both.

    I think using a homemade trigger group wasn't that good of an idea, because I think I just unlocked the secret giggle-switch on it 😬

    Not American I bought a new trigger pack and just swapped the trigger shoe. the metal reset was about 80USD to get from a SCS so i made it at work with an angle grinder and files. Works OK but i have to tune it slightly to make it more smooth.

    Not illegal here but a gray zone.

    Pistol Compensator?

    Has anyone successfully printed a functioning pistol compensator? I designed and printed one using PA6-CF and it separated in half after the first shot. I’m thinking I am going to have to change print orientation, but just curious what others may have done.

    Almost finished with this build. It's not exactly to the point I would say it's finished. But it is definitely at the testing stage. Hopefully I can get some rounds through it this evening and start the process of debugging.

    Anyone got one on hand or care to guess what size they are? Should be “90 degree torsion spring” but what size wire, how many turns and coil diameter.

    I’m guessing like 0.2mm wire, 3-6 coils, 10-15mm legs.

    Stock -> Brace 🎉🥳

    Someone who sleeps in my bed accidentally ordered a strike industries folding stock 😱 instead of the brace like our great overlords demand for safety of course!

    I took the db brace thing based on the strike industries brace and just changed the mounting. Idk where or if the s i files are available. I couldn't find them so this works just as well. If I can figure out how to post is somewhere maybe I will.

    Finished my MAC-9 build with the velocity upper and lower parts kit. Printed with polymaker PLA pro. Modified the STL to remove the rails, optimized the print orientation for larger contact points with the print plate, and reinforced the rear of the lower.

    First outing was halfway decent. 3 malfunctions throughout 150 rounds. Thinking it may be magazine related. Magazine follower got stuck and didn’t push the rounds up and and 2 double feed jams. Any tips for the feeding issues? I’m using the curved sten mag that came with the files and Glock 17 extended magazine springs cut to about 3” longer than the magazine.
