The Libertas design incorporates integrated ambidextrous, anti-rotational Quick Detach sling mounts. On the magwell, forward of the trigger is a textured Memory Index Point for safely resting the trigger finger when not ready to fire. The magazine well is also enlarged and beveled to facilitate quicker magazine changes. The integral trigger guard is over-sized to allow room for larger hands or gloves. The front of the magazine well is also textured to allow it to be used as a grip for forward support. The specialized tension screw factilitates in eliminating play between the upper and lower receiver.Specifications:Franklin Armory Libertas Propietary Billet Lower ReceiverMachined from 7075-T6 AluminumHard Coat Type III Anodized Black, Desert Smoke, or Olive Drab GreenFlared Magazine Well for Quick Magazine ChangesAmbidextrous Push Button QD Sling MountsSpecialized Tension Screw - Eliminates Upper/Lower PlayIntergral Cold Weather Trigger GuardSerrated Memory Index Point for Shooting FingerTextured Front Area for Offhand Grip
