Lower Parts Kit, Forged

While not strictly limited to Umbrella receivers, we put this kit together as a high-quality option for customers looking to build-out their forged, mil-spec type AR-15 lowers without having to chase down individual components. This Umbrella kit includes all necessary parts to complete your forged lower receiver less the required stock assembly (receiver extension, end plate, extension nut, buffer, action spring, stock). In addition to the high-quality individual pieces, this kit includes a Schmid Elite single stage trigger/hammer group, Schmid ambidextrous selector (long lever + short lever), ambidextrous magazine catch, Magpul oversize aluminum trigger guard, and Umbrella’s own Grip 23T. For those not familiar, Schmid’s Elite GI trigger is a fantastic, but economical upgrade to the standard mil-spec AR-15 trigger. The pull is like the stock trigger but much smoother with a clean break between 3.5 to 4 pounds. And the Schmid ambidextrous 90° selector represents an excellent, but economical upgrade for the platform. Magpul’s aluminum trigger guard provides an oversized profile vs that of the straight mil-spec guard. Parts kit includes the following components:

Note: If you own, or have ordered an Umbrella billet lower, this is not the kit for that receiver. The Umbrella billets include a number of parts already, some of which are again included in this kit. To complete your Umbrella billet lower, look for our “Billet” parts kit.
