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 lower receivers we have to offer, check out our multiple collections.

Key Gun Laws in Kansas

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

Firearm Possession and Purchase Requirements

The state of Kansas does not impose restrictions on sales of firearms to minors but they are not allowed to possess any gun with a barrel shorter than 12 inches long. There are however exception to this if the minor is 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. No state permit or extra licenses are required to purchase a rifle, shotgun, or handgun.

All firearm purchases 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. Kansas 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 transfers do not require a background check. There is also no mandatory waiting period for gun purchases at stores.

Open and Concealed Carrying

Kansas is a constitutional carry state which means any legally eligible person at least 21 years of age may carry a firearm concealed in public without a license or permit. Persons underage wishing to conceal carry may only do so on their own property, residence or fixed place of business. Kansas will continue to issue ccw’s in the form of (CCHL’s) or Concealed Carry Handgun Licenses. The minimum age to obtain a license is 21 years old. But 18 to 20 year olds can apply for a provisional license. Applicants must complete an 8 hour handgun safety and training course that is state approved. Kansas recognizes all other states’ various forms of CCW’s for non-residents. To see more details of Kansas’ policies on concealed carry permits check this reciprocity map here.

NFA Restrictions

The state of Kansas does not have any NFA restricted items meaning residents are allowed to own machine guns, any other weapons, destructive devices, silencers, short barreled shotguns and short barreled rifles. There are also no “assault weapon” bans. Huzzah!

Magazine Capacity Restrictions

There are no magazine capacity restrictions in Kansas. Enjoy those sticks, drums and belt-fed box magazines! We carry plenty of standard capacity magazines like the Advanced Warfighter mag from Lancer which is a 30 rounder too. Our favorite color is the translucent smoke one.

Mandatory Storage Requirements

Kansas does not have any mandatory storage requirements but you should still exercise caution because you 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.


When in Kansas, there is no duty to retreat before force for self-defense can be used because there is a stand your ground law in place and a castle doctrine.

Ammunition Purchase

Kansas does not allow the possession, manufacturing, or sale of any handgun cartridge that is plastic-coated with a core of less than 60% lead by weight. Sellers are not required to maintain a sales record and no licenses are required to purchase or sell ammunition.
