YHM originally designed a Billet lower that mimicked a standard (forged) lower receiver, but after seeing the prototype production they decided to go with a receiver that was more stylized, something that didn't look like every other AR-15 on the planet. It was this mindset that helped YHM arrive at the Model-57, and in turn this lower receiver. This lower is crafted from 7075-T6 aluminum and has a hardcoat anodized matte black finish. It features over-sized magazine well chambers for easier magazine changes. It accepts all generations of PMAG's and Mil-Spec Upper receivers. It has a built in oversized machined trigger guard. It fits all standard parts (except for a trigger guard) and still fits, and functions with your standard upper receivers.

Spike's Enhanced LPK was designed for the end user who demands the most longevity possible out of the parts in their rifles. The core of the Spike's Enhanced LPK is the ST Battle Trigger which is a single stage Mil-Spec trigger, rounded hammer, and disconnector that is Nickel Boron-plated for a very smooth and crisp trigger pull that gets even smoother the more you shoot it. The Battle Trigger is held in place via KNS Gen II Mod II Anti-Rotation pins which keep the hammer and trigger pins from walking out (a problem in some 9mm ARs and full auto M4/M16s) and keeps the pin holes from enlarging and "egg-holing" after years and years of use. Spike's also included an ambidextrous safety selector, ST Billet Trigger guard with set screw, and Ergo grip featuring Spike's Spider logo. The Spike's Enhanced LPK also features a Mil-Spec bolt catch, mag catch, and mag catch button. As well as utilizing Mil-Spec detents, plungers, pins, and springs. The is kit also includes quality spiral roll pins for the trigger guard and bolt catch, as well as a 1/4" allen screw and washer for the Ergo grip.
