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 Oregon

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

Firearm Possession and Purchase Requirements

In the state of Oregon, anyone the age of 18 years or older is eligible to purchase a handgun or a long gun. There isn’t a permit or any extra identification required to purchase handguns other than a driver’s license. Unfortunately, per Oregon state law ORS 166.435, background checks are necessary for private sales or transactions as well. 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. So some states will choose to be as strict as possible with their background checks and some will be more lenient. Oregon does not require background checks for handgun or long gun purchases.

Open and Concealed Carrying

Oregon is a “shall-issue” state for ccw’s and offers them to residents in the form of a “CHL” or Concealed Handgun License. Open carrying is legal without a license for anyone who can legally own/possess a firearm and is at least 18 years old and it can even be done within vehicles. Some locations may be off limits such as federal buildings and Indian reservations. CHL applicants must be at least 21 years old and pass a state approved training course. Oregon does not honor CCW’s from any other states and only offers non-residents from contiguous states to be able to apply for an Oregon CHL. For more details on the state’s concealed carrying policies check out Oregon’s reciprocity map here.

NFA Restrictions

Full automatic machine guns are allowed in the state of Oregon as it’s a very NFA-item friendly state. There are also no NFA items restrictions in Oregon nor are there any “assault weapon” bans either.

Magazine Capacity Restrictions

There are no magazine capacity restrictions in Oregon. Enjoy those drums and belt-fed box magazines! We carry plenty of standard capacity magazines like this 30-round magazine from Lancer. Our favorite color is the translucent smoke one.

Mandatory Storage Requirements

Oregon does have mandatory storage requirements for firearms per SB 554. Therefore, Oregonian gun owners need to exercise extra caution and care when storing their firearms as you can be tried for negligently leaving your guns accessible to children or other people. If you need some good ideas or best practices for storing your guns and gear here are 5 firearm storage options.


Oregon is not a castle doctrine state and does not have a stand your ground law in place however there is precedence from the Oregon Supreme Court case “State of Oregon v. Sandoval” which ruled that Oregonians do not have a duty to retreat when faced with a violent confrontation so exercise good judgement as any response with force still has to be justified. Oregon law also states that residents are allowed to use deadly force to prevent certain property crimes so be sure to look into that more as it is not a blanket statement.

Ammunition Purchase

The only type of ammunition that is prohibited in Oregon is ammo that has bullets coated in teflon. Other than that Oregon does not require a license for the purchase, possession or sale of ammo so long as long gun ammo buyers are at least 18 years old and handgun ammo buyers are at least 21 years old. Online ammo purchases require buyers to be at least 21 years old.
