I mostly keep it with the 22 upper on, but still hoping to find some .32 at a decent price.

It eats Aguila super extra subs and standards without much trouble, but it does get hella dirty with the can on there.

The Czeckpoint receiver comes with their own safety lever which does not have the hole for full auto. It also has a smaller diameter shoulder on the far end so a parts kit safety will not fit into the receiver. Do you still cut off the tail on the sear?

Mars Triggers just teased a VZ61 FRT. Could it possibly be finally happening?

Received approval for the can the other day, and overnight for the first of my 3d printed lowers as an SBR. Prior can of same design worked well on my MP5, should do fine on these. PA6-GF on this one.

Bought this in 22lr complete. Love it but jams so much.

Anything to help with the jams? Is it just the break in? I’ve put about 200 rounds so far and it does shoot a bit better but still jams often. Is it possible to swap out for the .32 acp upper. Will this lower work ?

With the price and rarity of the metal lowers these days, I have decided to just print my own!!! I have recommended this to many others as it's so easy and comes out so nice. This was printed on the Qidi Q2 printer in SUNLU PLA+ 2.0 as this was meant to be a test frame and I'm going to print in PA6-cf for the final build.

This is the super safety lower that uses an AR15 FCG so the super safety can work with the gun. I ordered an all metal SS housing, trip bar, lever, and cam. I made a post about them in this sub a couple weeks ago, and although people shit on it, the parts fit PERFECTLY. I haven't quite got it built yet (will do tonight) but seems like all is good.

This one has the original stock adapter but there are options in the files to use a rail type adapter, top rail or no top rail etc and a few grips options. I'm going to do the original grip style but that fits onto this frame to keep the look the same.

Now if I just got my form 1 bullshit completed so I can actually put the stock on the thing. I'll update when I build and test shoot it as a pistol until my form 1 approves.

Shoot me any questions!!!

Beta version I printed the other day. Pla+ filament for trial. Had everything but a dang AR safety, spring and detent on hand. Got a partial lower kit in and put it together. Tried with a resized case with just a primer to insure it would strike properly, yep. And then 5 rounds to check it out. Yep, works. Just std AR innards. No frt. Not interested in totally wasting money, especially for the cost of ammo, even if I am reloading most.

Added a Makarov variant to the Skorpion collection 🦂 Next up is the .380

Delayed blowback vz61 ive been working on. And yes it does work, ive put 10 rounds through it this morning.

So I just impulsively bought the KVAR painted Vz61 kit with intentions to print the lower. Not until i opened the print file and read the "Read Me" did i realize i just bought a surplus kit and it probably has a full auto capable bolt/parts. It does not specify on KVAR. What are my options here. Can i make this thing semi auto only or do i have to go do federal paperwork now before I do anything with this kit? Thanks. And i know this is as dumb as it gets. i saw the kit and just bought it instantly without a thought.

Much like the rest of you I love this little thing. Its so much in such a small package. Which got me thinking. How hard would it be to make a drone that could use it?

Most of the questions for this idea are obviously for the drone community, BUT for you boys:

How much of this do you think could be removed and this gun still function? Weight being the primary factor.

Been trying to put my barrel pin in, but it gets halfway then stops. I don't wanna just keep hitting harder and looking inside I see something partially obstructing the hole.

Is that possibly the barrel or is it something that helps hold the barrel?

Upgrade for my Skorpion.

Waiting for the rail.

Want to change this cheap red dot. I am hesitating between one Eotech XPS2-0 (large & expensive) or one Holosun Aems...

Still have to true up holes but it does all fit.

Next step - trimming a mil spec hammer to be the correct length and working on a trip for a FRT

For anyone trying to figure out the best way to thread their muzzle, I used a 12mm shaft collar (link in comments) in my threading coupler I designed to ensure perfectly straight threads. Before firing through any muzzle devices, always ensure that your bore is concentric with your device and there are no obstructions.

Anyone running a good surplus or similar style case for these? I don't want a soft case, and I'd rather it not be some PLANO brand type stuff either. I'm considering gutting an old snap on drill case but like I said, I'd prefer something more period correct/surplus looking. Bonus points if it'll hold two 69 style!

Rolled the dice on a ST Vz61. I know they have been hit or miss. I also know they pay attention to these posts and have been trying to work out the kinks. 100 rounds and not an issue so far. I will say that I sprayed some CLP in the action because it looked pretty dry, and I used S&B fmj. As far as accuracy, it's hitting steel at 15 yards or so. I'm not going to worry about getting the sights dialed in until my tax stamp comes back. At the price, I'm very happy with it so far. Ymmv

My rate reducer/pistol grip mount does not want to thread very far into my Czeckpoint receiver. So I decided to buy a tap/die set to clean up the threads. I checked the original blueprint and it calls for an M16 x 1mm thread so that is what I ordered. I don't have that tap yet but I just measured my rate reducer thread and it measures .585", or 14. 88 mm so it is really an M15, not M16.
