“Zip Gun" vs. lawful “build your own” rifle
Assuming you don’t live in a state with oppressive gun statutes, what’s the difference in building an illegal “zip gun” (as a rifle) and buying or machining all the parts for a speciality rifle (like many here do for precision/ hunting rifles)?
Ie where is the line?

"The line" is........NFA or not NFA
No Federal law prohibits someone from making their own firearm.
Most "zip guns" are illegal not due to being a homemade firearm, but because they lack certain features that make them a Title I firearm. Examples: -No rifling in a handgun barrel. -Barrel length of less than 16", OAL of less than 26" for a rifle. -Barrel length of less than 18", OAL of less than 26" for a shotgun. -OAL length of less than 26" for an Other Firearm. Most common "zip guns" will utilize cheap, easily acquired items like lead pipe for the barrel/chamber, nails for the "firing pin", etc. Home Depot doesn't sell rifled lead pipes. So if you want to make a firearm using that, you;ll need to attach a shoulder stock and have a barrel of at least 18". Any shorter and you'll have an illegal SBS. OR Build that smoothbore firearm without a shoulder stock and with an OAL of more than 26" to classify as an Other Firearm. Any shorter and you'll have an illegal AOW.

There is no federal legal definition of a zip gun.
Crude as you like, as long as it meets the requirements for rifle, pistol, or shotgun, it is legal to make for your own use. Just be sure that your piece of radio antenna is 18"+ long and the overall is 26"+ so it counts as a shotgun. |

If it does not fit the above federal definitions, then it may be a Title II (NFA) firearm that requires registration and tax payment. A Form 1 would need to be filed and approved before the build. If it meets the definition of a short barreled rifle (SBR) or short barreled shotgun (SBS), the tax is $200. If it meets the definition of an "any other weapon" (AOW), the tax is $5.

I thought an AOW was $200 to build and $5 to transfer.

Zip guns are generally made with limited tools and resources and almost always subquality materials. Their very nature makes them unsafe and highly unlikely that a mfg license will have been applied for. They may be good for one shot but their best application is for gun buybacks.

Zip guns are almost always going to be smoothbore because making rifling is difficult and more expensive. So, because most will be smoothbore they have to have a barrel at least 18 inches long and overall 26 inches to not fall under NFA regs.
Easiest way to skirt that now is do what Franklin Armory did and make straight rifling (i.e. grooves) instead. Doesn't do anything to add accuracy or stabilize a bullet, but it makes any gun with a barrel under 16 inches legal. Would probably work really well for a .45 Colt/.410 zip gun. Low pressures and 000 Buck multi projectiles not being spun by rifling.

Let's see: 1- 4" of 1/2" pipe from Home Depot 85 cents (barel) 1- 3" x 4" x 2" piece of wood from Home Depot 30 cents (grip) 1- Clothespin with metal spring 15 cents (hammer) 1/4 ounce of gorilla glue 25 cents (gold it all together) 5 minutes to put it together So for $1.55 I can get $75 back? Can I scale this up to do 12 an hour, that's $881.40 per hour! Sounds like a franchise opportunity to me

With Dogtown Tom as our compliance director and Zxcebob as the engineering director, I think we have a team!

Could make a broach and use it on a shop press to cut some straight rifling in. Would be even easier if there was a company who made broaches to do just this. That way the process stays entirely legal.

Good to know MTT TL. Everything you need in a gun barrel material; soft, heavy, and a low melting point.

Numrich (Gun Parts Corp.) used to sell barrel blanks, in various lengths and calibers. Most were unchambered, and I think they were cut-offs from who knows what. Some were a bit pricey, and others were dirt cheap and would be a way to get a rifled barrel for a DIY project.

Home Depot doesn't sell lead pipes at all, but you don't have to go to ancient Rome. Lead piping was common in houses until the 1920's and in solder until 1986. If your house was built before then you may still have 'em.
Gunparts still sells barrel blanks and barrels. A Google search for 'zip gun' returns 13,100,000 results. Including plans and how-to videos.
