Built for Hard Use
The Mitchell Defense 11.5″ Pistol is designed to provide consistent performance across a wide range of conditions. Each component is selected to support durability and reliable operation.
Cold Hammer Forged Chrome-Lined Barrel
Cold hammer forging strengthens the barrel structure while chrome lining improves corrosion resistance and extends service life. This ensures long-term performance even under sustained use.
Armorlube-Coated MD Carbon Cutter Bolt Carrier Group
The MD Carbon Cutter bolt carrier group features an Armorlube coating that enhances lubricity, reduces friction, and improves corrosion resistance. This promotes smooth operation and simplifies maintenance.
MD Enhanced Flat Wire Buffer Spring
The enhanced flat wire buffer spring provides consistent spring tension and improved longevity compared to traditional round wire springs, contributing to reliable cycling.
SBA5 Pistol Brace
The SBA5 pistol brace is designed to assist in stabilizing the firearm when firing with one hand. It attaches to the user’s forearm to provide additional support and improved control while maintaining the intended pistol configuration.
Balanced Platform Design
At 5.6 pounds, the 11.5″ configuration offers a stable shooting platform while maintaining a compact overall size.
Why Choose an 11.5″ AR Pistol?
The 11.5″ barrel length is widely considered one of the most balanced configurations in the AR platform.
Compared to a 10.3″ configuration, the 11.5″ platform provides slightly increased dwell time and velocity, which can contribute to smoother cycling and improved overall performance.
When compared to longer configurations such as 12.5″ or 14.5″, the 11.5″ platform maintains a more compact size while still delivering strong ballistic performance.
For shooters looking for a compact platform that offers a balance of size, reliability, and performance, the 11.5″ configuration is a proven and versatile option.
Product Description
The Mitchell Defense 11.5″ 5.56 NATO Pistol is engineered for shooters who want a compact platform that delivers consistent and reliable performance.
The cold hammer forged chrome-lined barrel features a 1:7 twist rate designed to stabilize a wide range of modern 5.56 projectiles. Chrome lining enhances durability and corrosion resistance, making it suitable for extended use.
The system operates on a direct impingement system with a carbine-length gas system, providing consistent cycling and efficient operation.
Combined with the Armorlube-coated MD Carbon Cutter bolt carrier group and the Mitchell Defense enhanced flat wire buffer spring, the platform delivers smooth and dependable performance.
Finished with B5 Systems furniture and a QD sling mount end plate, the Mitchell Defense 11.5″ Pistol provides a balanced and reliable configuration.
