Franklin Armory's custom designed billet lowers are now available! This 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. These Built Lower Receivers come with a carbine length 6-position collapsible stock buffer tube without any stock installed. This allows the customer to install whatever stock they prefer without paying for a generic one that they may likely remove anyway. - Lower Receiver: - Franklin Armory Libertas Proprietary Billet Lower Receiver - Machined From 7075-T6 Aluminum - Hard Coat Type III Anodized Black - Flared Magazine Well for Quick Magazine Changes - Ambidextrous Push Button QD Sling Mounts - Integral Cold Weather Trigger Guard - Serrated Memory Index Point for Shooting Finger - Textured Front Area for Offhand Grip - Specialized Tension Screw - Eliminates Upper/Lower Play - Franklin Armory Binary Firing System - Ergo Ambi Sure Grip - Magazine: - Magpul Pmag P20 or P30 Depending on Availability - Anti-Tilt Follower - Stock: - Six Position Receiver Extension Installed - MILSPEC Diameter - No Stock Included - Additional Features: - Comprehensive Safety Manual - California Certified Cable Lock - Specify Color: BLK - NO SALES TO THE STATES OF NEW YORK DELAWARE and NEW JERSEY
