The XO-26™ is a cross over between rifles and pistols.  The 26 refers to the absolute minimum length of the firearm as allotted by federal law.  However, we chose to make the length an inch longer than necessary so that it would still be long enough to qualify as a non-AOW even if the muzzle device was removed.  This length also makes it easier to see the chamber indication.

Buying a complete firearm or lower from Franklin Armory® is easy, safe and legal. Federal law requires all firearms be shipped to a licensed dealer.

During the checkout process, enter the name and contact information for your FFL in the special instructions field. Please be sure to have made prior arrangements with your FFL, to include having your FFL contact us with all of their proper documentation for verification of their license.
