Dirty Bird MCFA Ambidextrous Matched Receiver Set

Introducing the Dirty Bird Industries Multi-Cal Forged Ambidextrous (MCF-A) Receiver Set. Lower Receiver: Start with Quality Forgings All MCF-A lowers are machined from top-tier 7075 Aluminum Forgings from Cerro Fabricated Products. It is a common misconception that all forgings are created equal. Cerro Fabricated Products has been a leader in precision forging, machining, heat treating and more since 1915. Meticulous Machining We wanted perfection, so we teamed up with the folks at MVB Industries. MVB, best known for their innovative ARC-X PDW Stock, is one of the industries’ best kept secrets. And while we’d love to keep them all for ourselves, we can’t talk about the quality of this lower without giving huge props to their team. Lots of companies are known for their creative vision, others are known for their unwavering attention to detail. MVB does both, and they do it very, very well. A Quality-Control Centered Process You’ll notice that in addition to ATF issued serial numbers, all of the lowers feature a unique identifier machined near the pistol grip interface. This is for tracking each individual unit throughout the production process. This added step allows QC staff to trace any potential quality issues back to an exact machine and a given batch, no matter how long it has been since that unit was produced. Features: Ambidextrous Bolt Catch / Release The Dirty Bird MCF-A Lower Receiver uses MVB’s patent pending mechanism that implements an Ambidextrous Bolt Catch / Release with elegance, rather than complexity. The mechanism both releases and actuates the bolt catch automatically. If the bolt is already in battery, hitting the lever will raise the bolt catch, enabling you to lock the bolt back. If the bolt is locked-back, hitting the lever will release the bolt. Simple. The mechanism is non-interfering, meaning that if the Ambi bolt lever is damaged during hard-use or movement is blocked by debris, the standard bolt catch / release paddle still functions flawlessly. The mechanism consists of only 4 proprietary components, all of which are machined from Billet S7 Tool Steel and QPQ Nitrided which means pretty much anything on the lower would break before they do. Utilizes zero hex screws. Instead, the Ambi Bolt Catch lever is installed with a standard bolt-catch roll pin. This simplifies things and gives the unit a higher level of serviceability. Self-Adjusting Receiver Tensioner The MCF-A utilizes a spring-loaded plunger to reduce slop between the upper and lower receiver. No more tension screws or accu-wedges. Upper Receiver Features: 7075-T6 Aluminum Forging from Cerro Fabricated Products Mil-Spec, MIL-A-8625 Type III Hardcoat Anodized Finish Precision Machining To Ensure Flawless Use with Aftermarket Products The Dirty Bird Ambidextrous Receiver Set is the perfect building block for your next AR Build and we promise that you will not be disappointed. Made in the USA Backed by the Dirty Bird Limited Lifetime Warranty *Limited compatibility with anti-walk / anti-rotation pins. We can confirm compatibility with Dirty Bird Brand Anti-Walk pins. *Black color is type 3 hard anodized per mil-spec. Other colors will be Cerakote. *Will not come with takedown/pivot pins.

San Tan Tactical STT-15L Lite PILLAR Billet Receiver Combo - STT-15L-Lite-PILLAR-Combo

The San Tan Tactical STT-15 Lite Pillar Billet Receiver Set was designed from the ground up to be exceptionally lightweight without making any compromises. Each receiver set is precisely machined out of a solid block of 7075-T6 aluminum on state-of-the-art CNC machinery. This allows for a greater degree of precision for extremely tight tolerances and additional features like lightening cuts to reduce weight and an enlarged magazine well and trigger guard. The STT-15L billet AR-15 receiver set from San Tan Tactical offers uncompromising performance, so you can build the rifle you need. Features: Machined from 7075-T6 aluminum Mil-Spec Type III hardcoat anodized black 3D CAD Designed for maximum weight savings Threaded bolt catch pin Compatible with Mil-Spec parts kits .154” trigger pin holes Lightened receiver cuts Enlarged trigger guard and beveled magazine well Receiver tension screw Upper receiver comes assembled Matched set weighs 14.6 Oz The lower receiver makes assembly easy thanks to the limination of roll pins, but a lower parts kit is still required to finish it. Compatible with all Mil-Spec components like a trigger with .154” pin diameters and ambidextrous safety selectors. However, the upper receiver comes fully assembled with a dust cover, eliminating the forward assist to further improve weight savings. An additional feature of this AR-15 billet receiver set is built in receiver tension screw that can be accessed through the bottom near the pistol grip. San Tan Tactical believes in carrying on the tradition of American designed and made firearms and that is exactly what they are doing. Their receivers and lower parts are some of the most innovative in the industry and they are proud bring you a product not only made from American sourced materials, but American machinery as well. They take the time to listen to customers critiques and are constantly evolving their products to satisfy your needs.
