Frequently Asked Questions
The LEO TakeDown is compatible with most free-float hand guards. Hand guards that are compression locking with a flat edge work the best. Hand guards with anti-rotation features that protrude over the upper receiver will not work unless the protrusions are removed. The LEO TakeDown is NOT compatible with D-Ring mounted hand guards.
When properly installed, the LEO TakeDown moves the hand guard, barrel nut forward approximately 1” toward the muzzle. On pistol length, and some carbine length, barrels we recommend barrel nut lengths 2 in. and shorter. For barrel nuts longer than 2 in., a “wedge” may need to be cut into the leading edge of the barrel nut to allow the gas tube to free float.
A – Check to make sure the hand guard does not have any appendages protruding back further than the barrel nut. B – The barrel nut is not properly seated on the barrel and may require shimming. Contact us if further assistance is needed.
Recommend a shorter hand guard. Keep in mind, the LEO TakeDown will move the hand guard barrel nut forward approximately 1” on the barrel.
The traditional D-Ring supported hand guard (M-4 clam shell) requires mounting the hand guard using receptacles in the front and back. A modified, or cut down, free float hand guard can be used with the traditional A post but the coupling is not designed to support the traditional D-Ring clam shell type hand guard. We recommend a free float, compression locking hand guard that has a flat surface on the upper receiver end.
Mil-Spec style AR-15 barrels with a diameter at the barrel extension of .975 to .980 in.
The LEO TakeDown adds no additional length to the barrel or the firearm. However, the LEO TakeDown moves the barrel nut down the barrel 1 in. making rails functionally 1 in. longer. Consider this when choosing rail length so as not to cover the muzzle.
The LEO TakeDown is compatible with all calibers that currently run out of the AR-15 chassis.
Those are the lockout studs, which correspond to index marks on the slip ring that allow you to insert and remove the barrel when aligned. To lock the barrel in place rotate the index marks out of alignment with the studs. These are set at the factory, please do not adjust.
If the gas piston is the diameter of the gas tube or smaller, professional gunsmith modifications are required.
