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 percent lowers we have to offer, check out our multiple collections.

Key Gun Laws in South Carolina

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

Firearm Possession and Purchase Requirements

To purchase a long gun in South Carolina buyers must be at least 18 years old. To purchase a handgun in South Carolina buyers must be at least 21 years old. No extra permits are needed to purchase handguns or long guns in South Carolina nor is extra registration necessary. South Carolina’s minimum age for possession of handguns is 18 years old and there is no minimum age restriction for possession of long guns. In the event a minor is in possession of a handgun the normal exemption applies when minors are in the direct supervision or presence of their parents, guardian or when attending a hunter’s or firearms safety course, using the gun for target practice or recreational shooting at an established range, involved in an organized competition, hunting or trapping with a valid license, traveling to and from these events, or at their own residence with permission and supervision of a parents or a legal guardian.

All firearm purchases and transfers require a background check not including private party transfers (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. South Carolina is not a point of contact for the NICS and as a result, dealers must conduct their background checks by going through the FBI along with another background check that is to be conducted by the state police or local chief of police. South Carolina CCW holders are exempt from background checks when purchasing a gun from a FFL dealer.

Open and Concealed Carrying

South Carolina is a “shall-issue” state for ccw’s with permits being issued at the state level by the South Carolina Law Enforcement Division or (SLED). CCW’s are offered to South Carolina residents in the form of a “CWP” or Concealed Weapons Permit. Open carrying is legal for those with a CWP only. CWP applicants must be at least 21 years old and complete a state approved course. be able to explain why they need a firearm and must also be able to provide three references. Non-residents that own property in the state are also eligible to apply for a CWP otherwise applicants would have to be military personnel stationed in South Carolina. For more details on their concealed carrying policies see South Carolina’s reciprocity map here.

Residents in South Carolina can legally purchase and possess all NFA weapons and related items however, for automatic weapons, the state restricts ownership of any guns that were made after May of 1986. Also, South Carolina does not have any “assault weapons” bans.
