USED Custom SOLGW M4 AR-15 Pistol – Daniel Defense RIS II – KAK K-SPEC BCG – Super Safety

This custom AR-15 pistol is built around a Sons of Liberty Gun Works Model M4 lower receiver and combines components from several respected manufacturers. The lower is marked “Model M4 / 1776-469193 / CALS MULTI” and is equipped with an aftermarket Super Safety-style trigger/selector system, upgraded pistol grip, and pistol-style rear receiver extension.

The upper features a Daniel Defense free-float quad-rail handguard, appearing consistent with the M4A1 RIS II 12.25-inch rail, complete with Picatinny rail covers and a folding rear sight. Internally, the photos clearly show a KAK Industry K-SPEC bolt carrier group. The front end is fitted with a multi-port muzzle device. Cosmetic wear is visible on the selector, trigger, rail edges, and several control surfaces, but the overall build presents in good to very good used condition.

This is a parts-built configuration rather than a factory-complete SOLGW model, so the exact barrel manufacturer, barrel length, chambering, upper receiver manufacturer, muzzle device manufacturer, and internal trigger components should be physically verified before final cataloging. The lower is marked multi-caliber; the photographs alone do not conclusively establish the chambering.
