As many industry insiders are aware, the addition of a secondary vertical grip to a pistol creates a class of firearm called an “AOW,” or any other weapon and requires an NFA tax stamp.  Franklin Armory management made the argument to ATF that the XO-26™ configuration above is not readily concealable and therefore should not be classified as an AOW even though it has a secondary grip.  ATF agreed.
On March 14, 2011, the Chief of The Firearms Technology Branch of the Bureau of Alcohol, Tobacco, Firearms, and Explosives, authorized the sale of the above configuration without the need for any NFA permits!  What is shocking is that it was also defined as a non-pistol.  The 4473 would only need to be filled out with “other” checked off.  Franklin Armory™ is proud to be the first company in the nation to be able to shepherd this project into fruition.
California residents will find that 12001 PC will still define this firearm as a pistol, but thankfully there is not an analog to the AOW classification in state law.  California buyers will have to be at least 21 years of age, and the DROS form will require one to check “Pistol.”
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.
Besides 5.56 NATO, the XO-26™ is available in 7.62x39.  After careful study of the external ballistics of both cartridges in 11.5” barrels, we found that the 7.62x39 produces over 1200 foot pounds of energy while the 5.56 NATO creates 950 FPE.  We believe that the 25% power increase, combined with the heavier weight and greater frontal area of the 7.62x39 cartridge, will make a more effective firearm for defense and even hunting.
