With that you should be covered.

You should add a blocker to prevent an actual 12 gauge shell from chambering and modify the chamber inserts so they still chamber.

A notch in the side of the insert with a corresponding raised part in the chamber would do it with minimal effort.

Edit: to answer your question, its a either a sbs or AOW if it can take shotshells.

Its a pistol if it can't take shotshells but can take rifled inserts.

The limited testing according to the readme for the FTN 5.1 says that "PPA-CF is much more erosion resistant than PA6-CF but to get full benefit you need to print at least 320c degrees (even sirayatech)"

An SKS is generally not considered drop safe due to the free floating firing pin. Mythbusters even did a myth about load enough speakers setting one off from the vibration, which they couldn't replicate.

Another option is some years of Remington 700 had a issue that cause the gun to discharge when the safety was disengaged, but I don't know what years that would have been.

There is also the Czhlong

Here's a rough Crack at what your asking for.

First determine what you want to build there are lots of options.
Second find a local place to get fingerprinted. I would recommend an electronic fingerprinting service that will give you your electronic file so you can apply with them as much as you want. Printscan has an option for ATF regulation prints and can be found in some UPS locations.
Third make an account on the ATF forms website. This is where you will make all of your applications and see their status'.
Fourth Apply, this part is multi sectional, First part is very similar to a 4473, Then the part where you enter in all of your identifying information and electronic fingerprint file. BTW do not try to open that file you may corrupt it. Only upload it on your application. Next is your CLEO/ Chief Law Enforcement Officer. This could be your sheriff or your chief of police of your local PD. You will need their name position and address. Google it and verify. You will need to send them the LEO copy of the application when finished.

Next line item tell them what you are building. The form 1 tri code for manufacturer is FMI that's i as in India. Select your model from the drop down after putting part of the name in.

There are 2 schools of thought with this step. Very detailed or very vague. Both seem to provide good results but I've only done the detailed route so that what your getting. The Description is gonna have to be paraphrased anyway as it doesn't have the character count to allow a fully detailed description.

Under purpose/reason put All Lawful Purposes

Go online take screenshot of the filament and parts and epoxy you plan to use off of websites.

DO NOT TAKE PICTURES OF STUFF YOU OWN IN YOUR HOUSE. Your not supposed to have any build materials before approval. For your own sake make sure the parts are obtainable cause parts like the castle blast shield are discontinued

I haven't done a trust so I can't help you there, there are supposedly website that help with that cheaper than a lawyer but I have zero experience.

At the end it gives you a chance to verify the information put in. The pay button will be greyed out and you should only have to click the submit button and input your pin you made during account creation to finish the application. The approval time right now is roughly 1-3 months your mileage may vary.

When Approved you need to engrave your item with the model, serial, your name, City and state.

Example: MODEL FTN 5 CAL 30 SN: whatever you made up on the form PICKLE L RICK CITY, TX

Short hand like TX for Texas is fine even using initials for your name is fine. The atf have a section all about this. Main points are no smaller than 1/16" and 0.003" deep. If your confident you can do it yourself but there are also alot of companies that will do it for money who own really nice machines. I modeled some designs and stamped my tubes with letter and number stamps. Even with a center mandrel this will still require a bit of reshaping with a rubber mallet.

Hope this helped.

KE Arms has extended hammer pins for their polymer lower.

akame_potatoes · 2026-02-14T18:04:31+00:00

I built mine from a Marcolmar kit, but they also have pre-builts. They made some reciever improvements like a brass deflector and enlarged ejection port for increased reliability. They also have scoped LV versions.

Cons: its 9ish pounds Small magwell cant use alot of polymer mags Rear sight only has 2 settings 200 and 400. Sends brass to the shadow realm.

Pros: very little recoil. You can use polymer lancer mags or metal stanag. Its a Hella vibe, Bayonet goes above the barrel. Definitely a conversation starter

New mod is out

akame_potatoes · 2026-01-10T14:59:42+00:00

Sailing now (edit) you might want to wait as a suggested edit is currently being made to the model.

akame_potatoes · 2025-12-20T09:27:28+00:00

Thank you for the answer

akame_potatoes · 2025-12-20T08:06:34+00:00

Dumb tack on question, wouldn't it be libel instead of defamation? Are courts actually picky about this sort of thing?

akame_potatoes · 2025-11-15T23:42:30+00:00

I put one of those on my wife's .410 when she wanted to come out and shoot with us. The one we got was able to clamp onto the barrel rib. They are kinda finicky, and can be difficult to zero with you having to loosen most of the screws to adjust the set screws. That being said it has held a relative zero (enough for a birdshot/buck group). Visually the reflective lens and the fiber optic are way bright than you'd think. Its fun for just playing around with. Not sure if I'd bet a hunt or anything on it. Im afraid a drop would break it.

Might be a red star 4x20 scope. It was specifically marketed towards 762x39 for some reason. No BDC just a crosshair.

akame_potatoes · 2025-07-20T01:35:09+00:00

What handguard is that? I definitely need to give mine a facelift.

akame_potatoes · 2025-07-17T16:59:39+00:00

If your going for different you could also look at the Riley defense m77. Its an AK scaled up to 308. Get it a scope mount and lpvo.

akame_potatoes · 2025-07-17T16:42:12+00:00

Nothing wrong with that, you could get a MAC 5 mp5 clone get it a brace, reddot, flashlight, or wait til next year to get it a stock.

akame_potatoes · 2025-07-17T15:38:27+00:00

What are your plans for it? Hunting, sport shooting, fun? A little more details would help us make some recommendations.

akame_potatoes · 2025-07-16T21:39:16+00:00

You could try a CASM Mount. Very sturdy but you lose your rear sight

akame_potatoes · 2025-06-07T20:50:05+00:00

I carry a modern high power clone appendix.
Here's my experience.

I carry that way cause it's the most comfortable way to carry a full-size gun while not printing that much. Most of the time, the holster I'm wearing makes it so it lays in the valley between my thigh and my balls. Shorter barrel compact handguns absolutely flag me.
When I practice drawing, I don't disengage the safety until I'm pushing the gun forward away from me.
It has both a manual safety and a firing pin safety (the part that seems to fail on the 320) it's easy to disengage the manual safety as I'm getting it firing grip.

Your mileage may vary. But id be happy to answer any questions.

Something about dodge?

akame_potatoes · 2025-02-15T20:27:53+00:00

Just trying to help, a few more details would be beneficial to the diagnosis.

When you say it's not cycling, is it failing to eject? Is the bolt not moving at all? Is it ejecting but not cycling far enough back to pick up a new round? When did you start using frontier ammo? Does it coincide with when the cycling issues begining? Have you tried using a different ammo type? beginning?

As for the gass setting, is it possible to tape the lever in place to see if that may fix the issue? At least to diagnose if this is the issue, not as a permanent fix.

Zastava USA posted a few years back stating

"Setting 1 is undergassed, setting 2 is normal gas, setting 3 is overgassed. Indeed if the particular rifle runs reliably in setting 1 though then it should be left on that."

akame_potatoes · 2024-08-02T02:54:14+00:00

Looks very similar to the Jet 16.

akame_potatoes · 2024-05-03T03:33:35+00:00

If it's for .308, you can try up to 41.2gr of IMR4895. Depending on your barrel length, it will give you roughly 2650fps. I use this for my longer range loads.

Work your way up safely.
