Oregon residents: If you are making a firearm purchase online from us, please understand, you are more than likely going to go in the FICS background check line of over 37,000. This means, that there's a good chance you'll still be in line on the 18th of December and are at the mercy of what the Judge in Harney County decides. At the point, there's a chance you'll have to get a permit-to-purchase said firearm. There will be no refunds for people that go in line and have to wait. Purchase at your own risk. That being said, we will continue to fulfil orders as they come in. Thank you for your patience! ~ Fifty1Fifty Tactical, LLC
