Franklin Armory Salus Complete Lower Features The Franklin Armory Salus Complete Lower is machined from forged 7075-T6 aluminum and finished in hardcoat anodized black giving the receiver excellent durability against wear and corrosion in hard use. The Binary AR-Elite trigger allows the shooter to fire one round on the pull and a second round on the release adding a distinctive rate-of-fire option to a standard AR build. A three-position safety selector keeps the manual of arms familiar to any AR-pattern shooter switching to this lower. The specialized tension screw tightens the fit between upper and lower receivers reducing rattle and improving overall consistency. An Ergo Ami Sure grip provides a secure contoured purchase for the firing hand while the flared magazine well makes inserting magazines faster and more reliable during quick reloads. Ambi QD sling mounts let shooters attach a sling on either side of the receiver to match their preferred carry method. The lower ships complete with an SBM4 pistol brace and a Magpul PMag 30-round magazine giving builders a ready-to-shoot foundation right out of the box. For AR builders seeking a fully equipped binary-trigger-ready lower the Salus Complete Lower is available for sale at GrabAGun.
