What is an 80% Lower?

An 80% lower receiver is an unfinished and unserialized blank which requires some machining work from the end user to turn it into a 100% lower receiver, otherwise, what is legally considered as a firearm. 80 lowers are missing the trigger pocket and three holes that need to be milled and drilled out to be completed. Unless states have passed their own laws barring the possession or sales of 80% products; pending the ATF's updated decision from the most recent proposed rule 2021R-05 80% lowers are completely legal, not considered firearms and thus can be shipped straight to your front door. No FFL required. To explore the 80 lowers we have to offer, check out our multiple collections.

Key Gun Laws in Indiana

Other than laws regarding 80 lowers, these are the key gun laws you should be aware of if you reside or are traveling through Indiana.

Firearm Possession and Purchase Requirements

Indiana is an interesting state for firearm laws. There are actually no rules on how old you have to be in order to buy a firearm at the state level, so the federal laws kick in which mean residents must be at least 18 years or older and cannot be a felon. This is stressed because many people in Indiana have a felony on their record — about 5 percent of the state’s population, which is more than most states’ ccw permit holder population. The state of Indiana prohibits any person under the age of 18 to possess a handgun, assault weapon, or machine gun. For minors to legally possess and shoot guns, they can do so recreationally for target practice, hunting, and safety training when supervised at their own residence or at a range with a parent or legal guardian. Minors, however, can be gifted firearms from their parents. There are no licenses whatsoever needed to purchase a firearm in the state of Indiana and they do not need to be registered either.

All firearm purchases in stores/FFL’s require a background check (Dealer Record of Sale also known as 4473 form or “DROS”). While federal law requires federal firearm license holders (“FFL’s”:) to initiate background checks on buyers prior to the sale of a firearm, federal law also allows states to serve as their own “point of contact” and conduct their own background checks via state, federal records or databases, as well as the option to use the FBI’s National Instant Criminal Background Check System (“NICS”) database. Indiana is not a point of contact for the NICS and as a result, firearms dealers conduct background checks that are processed by contacting the FBI directly. Private party transfers do not require a background check.

Open and Concealed Carrying

Indiana is a “shall issue'' state when it comes to concealed carry and it does recognize CCW permits from any other states. Open carry and concealed carry is legal for Indiana residents with a ccw which comes in the form a “LCH” or License to Carry a Handgun.” Conceal carriers must be at least 18 years of age and have no requirement for firearms training To see more details of Indiana’s policies on concealed carry permits check this reciprocity map here.

NFA Restrictions

NFA weapons and related items are widely allowed in the state of Indiana. Specifically machine guns, silencers, any other weapons (AOW), destructive devices (DD), and short barreled rifles (SBR) are all legal for civilians to own. However, Indiana residents are not allowed to own short barrel shotguns (SBS).

Mandatory Storage Requirements

Ammunition Purchase

To buy ammo in Indiana buyers need only fulfill federal requirements and to be in good legal standing. To buy any bulk ammo online you must be at least 21 years old. The only ammo restriction in Indiana is a prohibition of certain kinds of armor-piercing rounds. The state does not require a license for the sale, purchase or possession of ammunition or require sellers to maintain sales records nor impose a minimum age for the purchase or possession of ammunition.
