What is an 80% Lower?

An 80% lower receiver is an unfinished and unserialized blank which requires so 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 a 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.

Key Gun Laws in Maryland

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

Firearm Possession and Purchase Requirements

The state of Maryland requires individuals to be 21 years of age in order to legally purchase a handgun. For long guns, the minimum age for purchase is 18 years old and there is no minimum age to possess rifles or shotguns.

All firearm purchases require a background check 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. Maryland’s Secretary of State Police acts as a partial point of contact for the NICS and as a result, dealers must conduct their background checks by going through that state department directly. Long gun related background checks/transactions are run through the FBI’s NICS. Maryland has a 7 day mandatory waiting period for all firearm buyers before allowing them to take their purchase(s) home.

Open and Concealed Carrying

When it comes to conceal carry, Maryland is a “may-issue” state which means local authorities must determine whether CCW permits should be given to any individual citizen or not. Open and concealed carry are both legal in Maryland but only for those with ccw’s in the form of “WCHP” or Maryland Wear/Carry Handgun Permit. However, open carry of long guns in public is permitted. Applicants must be at least 21 years of age, a resident of the state and complete a state approved 16-hour long firearms training course. For renewals, another 8 hour course is required.

NFA Restrictions

While the state of Maryland does allow for the ownership of NFA weapons and related items, they must also be registered with the state police on top of the existing federal requirements. Maryland does also restrict “assault weapons” which includes “assault pistols” and “assault long guns.

Magazine Capacity Restrictions

There is also a large capacity magazine ban in Maryland limiting all magazines to only 10 rounds.

Mandatory Storage Requirements

There are no mandatory storage requirements for firearms in Maryland but all handguns manufactured after 2002 must include an integrated mechanical safety device in order to be legally sold in the state.

However, you should still exercise caution and can be tried for negligently leaving your guns accessible to children. If you need some good ideas or best practices for storing your guns and gear here are 5 ways to store your firearms at home.

Self-Defense

Maryland is a castle doctrine state which means there is no legal duty to retreat when at home if met with a threat. However, when outside the home there is a duty to retreat if possible before responding with lethal force in the name of self-defense as there is no stand your ground law in place in Maryland.

Ammunition Purchase

In order to buy ammo in Maryland the buyer must be at least 18 years old. Persons 18 years old and up may purchase long gun ammunition. To purchase handgun ammo buyers must be at least 21 years of age. Maryland prohibits the manufacturing, possession or sale of armor-piercing bullets.
