RE: DLD CT4-2A ATF Variance Approval

To Whom It May Concern:

On 21 September 2017 Delta Level Defense, LLC  filed the formal paperwork with the ATF and the ATF Firearms Technology branch to manufacture a new model of firearm. The exact model of this new firearm is the CT4-2A, the new serial number sequence on file with both branches of the ATF is CT001 through CT9999. We filed a second variance to allow the receiver of the new firearms to be both a specific 9mm, as well as 5.56 & .300BLK. The ATF made the ruling that the 9mm receivers need to be marked specifically 9mm, and the 5.56 & .300BLK are to be marked “Multi”.

On 29 October 2017, Michael R. Curtis, Chief FTISB of the ATF, approved our entire lot of variance paperwork. Our official ATF Variance Control Number is 17-00898.

Additionally, Delta Level Defense, LLC has sent a prototype to the ATF’s Technology Branch for further classification and official categorization.

Should you have any further questions, concerns and or comments please do not hesitate to contact me directly.

RE: Definition of an Assault Weapon / Specifications Defining DLD CT4-2A as an OTHER FIREARM

To Whom It May Concern:

The State of Connecticut’s/ State of New York’s Department of Special Licensing and Firearms Unit defines an Assault Weapon as the following:

Any semi-automatic centerfire rifle, regardless of the date produced, that has the ability to accept a detachable magazine and has at least one of the following features:  1) A folding or telescoping stock; 2) Any grip of the weapon, including a pistol grip, thumbhole stock, or other stock that would allow an individual to grip the weapon, resulting in any finger on the trigger hand in addition to the trigger finger being directly below any portion of the action of the weapon when firing; 3) A forward pistol grip; 4) A flash suppressor; or 5) A grenade or flare launcher. A semiautomatic, centerfire rifle that has:  1) a fixed magazine that can accept more than 10 rounds of ammunition; or 2) an overall length of less than 30 inches.

Furthermore, the ATF Defines an “AOW”, Any Other Weapon, as:

 Any weapon or device capable of being concealed on the person from which a shot can be discharged through the energy of an explosive; ​A pistol or revolver having a barrel with a smooth bore designed or redesigned to fire a fixed shotgun shell;​ Weapons with combination shotgun and rifle barrels 12 inches or more, less than 18 inches in length, from which only a single discharge can be made from either barrel without manual reloading; and Any such weapon which may be readily restored to fire.

The CT4-2A DOES NOT under any circumstance fall under the definition of either an Assault Weapon or an AOW. Below are the follow characteristics defining the CT4-2A as an “OTHER FIREARM”.

1. Is NOT a Rifle as it does not have a buttstock. Features a spineless cylindrical tube that does not allow for any rifle buttstock to ever attach.

2. Is NOT a Pistol as it has a Forward Vertical Grip.

3. Is NOT a Pistol SPECIFICALLY under CT/NY Law as the MINIMUM barrel length is 12.5”. CT Defines a Pistol as have a barrel length of 12” or Shorter,

4. Is NOT an AOW, as it over 26” in overall length, and features a vertical forward grip.
