Griffin Armament MK2AL Ambidextrous AR-15 Lower

Griffin Armament MK2AL Ambidextrous Lower Receiver

The MK2AL represents a thoughtful approach to AR-15 platform building. This stripped lower receiver serves as the regulated foundation of your rifle, and Griffin Armament has engineered it with precision and purpose.

Materials and Construction

7075-T6 Aluminum: This aerospace-grade alloy provides exceptional strength-to-weight ratio while maintaining the dimensional accuracy necessary for reliable function. Griffin machines each lower to exacting tolerances, ensuring proper fitment with standard mil-spec components.

Hardcoat Type 3 Anodizing: The finish goes beyond cosmetics. This durable surface treatment resists wear, scuffs, scratches, and the corrosive effects of cleaning solvents and gun oils—essential protection for a component you'll handle frequently during builds and maintenance.

Ambidextrous Controls

Griffin includes two key features that enhance usability:

• Ambidextrous Magazine Release: Positioned for intuitive operation by shooters of either hand
• Ambidextrous Bolt Catch and Release: Allows charging handle manipulation and bolt lock-back from either side

These controls make the MK2AL an excellent choice whether you're a southpaw shooter or building a rifle for shared use.

What You're Getting

This is a stripped lower—the regulated component that requires additional parts (trigger group, safety selector, buffer tube assembly, and stock) to complete. It's an ideal starting point for builders who want to customize their rifle from the ground up.
