The Strike Industries AR-15 Enhanced Lower Parts Kit replaces the plain mil-spec controls on an AR-15 lower with Strike Industries' enhanced versions in one package. It suits a new build or an upgrade of an existing rifle, and covers the bolt catch, magazine catch and button, pivot and takedown pins, and the selector. A pistol grip is not included.

The SI 60-90° 3-in-1 selector shaft supports both a 60° short throw and the standard 90° mil-spec throw, and the SI selector lever and end plate complete the selector assembly. The enhanced pivot and takedown pins replace the standard mil-spec pins that join the upper and lower receivers.

Features:

• Enhanced bolt catch
• Strike magazine catch
• Strike magazine catch button
• Enhanced pivot pin
• Enhanced takedown pin
• SI selector lever
• SI selector end plate
• SI 60-90° 3-in-1 selector shaft
• Pistol grip not included

Kit contents are listed above, so check them against what your build still needs before ordering. Install on a mil-spec AR-15 lower receiver, then function-check the safety selector in every position and the magazine release with an empty magazine before firing.
