US Tactical Systems Clubfoot Stock "Back-up Twenty" with Push Button Design
Have the security of knowing you always have a spare 20-round mag as back-up just in case other ammo sources are not available. The BACK-UP TWENTY™ buttstock adds minimal bulk to the overall weapon, yet the extra magazine may be the difference between life and death. Constructed of durable Dupont® Zytel®, the stock retains the spare magazine using the same latching mechanism as the regular M16A2. Simply unlatch the textured rear plate, turn the plate to the side and press the standard mag release to drop the secured spare magazine.
The magazine is securely stored in a dust-free environment until the trap door is deliberately opened and the magazine release button is pushed.This stock replaces the standard M16A2 or AR-15 buttstock and maintains the weapons existing handling characteristics. Includes a standard size sling loop. Utilizes a mil-spec rifle length A2 buffer tube, spring and buffer which are not included.
