The KAK Industry AR-15 Complete Lower Parts Kit packages the parts to finish a stripped AR-15 lower receiver: a mil-spec trigger group, a KAK billet trigger guard, a standard A2 pistol grip and black oxide springs. It ships in a clear bag.

KAK Industry was founded in 2011 by Kurt Kosman to supply quality American-made components at affordable, sustainable prices. This kit follows that approach: a mil-spec trigger group with standard trigger feel, the familiar A2 grip angle, and a KAK billet trigger guard. It is a straightforward way to complete a first build or a budget rifle without sourcing parts one at a time.

Features:

• Mil-spec trigger group
• KAK billet trigger guard
• Standard A2 pistol grip
• Black oxide springs
• Packaged in a clear bag

Fits mil-spec AR-15 lower receivers. Lower parts kits take patience to install, especially the bolt catch roll pin and the small detent springs, so use a roll pin punch set and capture each spring as you go. Function-check the safety, trigger and hammer reset before firing.
