Guntec USA AR-10 Complete Lower Parts Kit .308 w/ Ergonomic Grip

The Guntec USA Complete Lower Parts Kit (LPK-GRIP-308) is a drop-in component set for finishing any stripped AR-10 lower receiver in .308 Winchester (LR-308 / AR-308) and is built to fit all lowers that meet DPMS specifications. Everything required to bring a bare .308-pattern lower up to a fully functional assembly is included, and it installs directly into the lower with no additional fitting required.

The headline feature is the Guntec ergonomic pistol grip, which uses a neoprene rubber construction and incorporates an integrated storage compartment inside the grip body for a more comfortable, practical carry. Two popular upgrades ship in the box alongside the standard parts: an extended magazine release for faster, no-look mag swaps, and extended takedown pins that make field stripping quicker and easier.

Inside the kit you will find the full complement of small parts needed to assemble a complete AR-10 lower: the trigger and hammer assembly with their springs, the bolt catch and magazine catch, the safety selector and detent, the buffer retainer and spring, the pivot pin, takedown pin, and all the detents and springs required for correct installation. A stock is not included; this is the lower parts kit only, intended to be paired with a user-supplied buttstock assembly and the stripped lower receiver of your choice.

Made in the USA by Guntec USA, the LPK-GRIP-308 is an economical way to complete a custom .308 AR build, replace worn internals, or refresh an existing lower with upgraded controls and a more comfortable grip. It is compatible with any DPMS-spec stripped AR-10 / LR-308 lower receiver.
