Griffin Armament MK2 Ambi Stripped Lower 7075-T6 Aluminum Black 689396839038 MK2AL

The Griffin Armament MK2 Ambi Stripped Lower is a new, premium foundation for your next AR-15 build, precision-machined from high-grade 7075-T6 aluminum to exact tolerances for seamless fitment with mil-spec lower components. Finished with a hardcoat Type 3 anodized black coating, it offers exceptional resistance to wear, scratches, and discoloration from solvents and oils. This lower includes Griffin’s ambidextrous magazine release and bolt catch/release controls, enhancing usability for both right- and left-handed shooters, with no additional accessories provided.

Designed for versatility, the MK2 features a 60° flared magazine well for smooth, consistent reloads and a mil-spec fire control pocket for compatibility with standard triggers. The integrated trigger guard and premium in-machine deburring ensure a refined, user-friendly platform. The ambidextrous controls, including left- and right-side bolt catch/release and a left-side magazine release, provide intuitive operation, though the standard right-side magazine release button is not included, requiring a lower parts kit for completion.

Weighing just 8.9 ounces, this stripped lower balances durability and lightweight performance, making it an ideal choice for custom rifle builds. Its robust construction and ambidextrous functionality cater to shooters seeking a high-quality, adaptable platform for tactical or recreational applications, backed by Griffin Armament’s commitment to precision and innovation.

  • Absolutely the best ambi lower for the money, hands down. It is worth checking Griffin Armament's site occasionally as they will run sales on "blems". I think I got mine on BF for like $150 shipped each. Run one of these on all my higher end builds.
