Description

The AR-STONER Performance Enhanced Lower Receiver Parts Kit for the AR-15 platform is the perfect choice if you are looking to build your next AR-15. This kit includes all the standard mil-spec parts used in an AR-15 lower receiver to ensure smooth and reliable operation with an enhanced fire control group and some Magpul parts. The AR-STONER Duty lower parts kits offers the rugged reliability of AR-Stoner, with the upgraded performance you expect from Magpul where it really matters. This winning combination makes this kit an economical way to build a complete lower, less a stock assembly of your choice and a stripped lower receiver. The AR-STONER Two Stage Enhanced Trigger Group for the AR-15 (Small Pin .154") is a mil-spec replacement trigger group featuring a non-adjustable trigger pull. With a first stage pull weight of 2.0lbs and a second stage of 2.5lbs this trigger is perfect for tactical applications or long range precision shooting. The hammer and trigger are nickel boron plated, providing a smooth pull and crisp break, enabling the shooter to stay on target. The Magpul AR Enhanced Magazine Release provides an enlarged contact surface for quick and fumble free magazine changes. With easy bolt-on installation with no gunsmithing required, the Enhanced AR Magazine Release is made of Mil-Spec hard anodized aluminum to provide durability and light weight. Developed from the operational experience of the Magpul Dynamics team, the B.A.D. Lever (Battery Assist Device) is designed to considerably improve the speed and efficiency of the AR15/M16 bolt catch. The B.A.D. Lever quickly addresses reloading and malfunction clearance shortcomings of AR15/M16 platforms by extending a paddle to the right side of the weapon, allowing manipulation of the bolt stop from the fire control/ready position with the right-hand trigger finger. Made from milspec-anodized aluminum, the B.A.D. Lever attaches to the standard AR15/M16 bolt release without permanent modification to the weapon. Functional for both left and right-handed shooters, the B.A.D. Lever also allows traditional bolt catch manipulation according to the AR15/M16 manual of arms. All mounting hardware included. The Magpul ESK (Enhanced Selector Kit) - AR is a modular, ambidextrous selector kit designed for AR pattern firearms that provides user-configurable selectors with modern ergonomics at an accessible price. The ESK - AR includes three levers: full, short, and hybrid, a selector pin, and a reversible, corrosion-resistant steel selector axle with 60 and 90-degree options. The selector pin comes in either black or red and secures the lever to the axle while acting as a selector position indicator. Installing the levers is easy and can be done without any tools. When it's time to remove a lever, all that's required is a punch. With smart design and ergonomic angles in the right spots, this kit allows multiple selector variations and easier firing hand selector manipulation to allow a modern manual of arms to be employed. Designed for Mil-Spec AR-pattern lower receivers. Not compatible with select fire receivers. Grip Style Options:Similar in concept to the MOE-K, the Magpul MOE-K2 (Magpul Original Equipment) is a drop in upgrade for AR15/M4 pistol grips with a more vertical grip angle optimized for short LOP weapons that bring the primary hand in closer to the shooter's body. With an aggressive new texture for positive weapon control, compatibility with optional Storage Cores for gear stowage, and a unique backstrap design for proper trigger finger placement, the K2 brings modern styling and ergonomics to the AR platform. Mounting hardware and a basic grip cap included.The Magpul MOE-K2+ Grip combines reinforced polymer body construction with comfortable, wrap-around rubber overmolding for maximum weapon control in adverse environments. Similar in concept to the smaller MOE-K, the MOE-K2 is a drop in upgrade for AR15/M4's that offers a more vertical grip angle, but in a full-size grip design. The steeper vertical grip angle is optimized for use on PDW (Personal Defense Weapon) configurations and improves comfort and control on short LOP rifles that bring the primary hand in closer to the shooter's body. With the rubber overmolding for positive weapon control, compatibility with optional Storage Cores for gear stowage, and a unique backstrap design for proper trigger finger placement, the K2+ brings modern styling, ergonomics, and comfort to the AR platform.
