This video delves into the Smith & Wesson M&P 2.0 platform, comparing its mechanical accuracy to Glock Gen 5 models. The discussion highlights potential improvements through aftermarket barrels and trigger modifications, such as Apex Tactical kits. It also addresses grip ergonomics and the subjective nature of firearm fit, emphasizing that with modifications and training, the M&P 2.0 can be a highly capable pistol.

This video explains the proper use of a torque wrench, particularly for AR-15 barrel nuts. It clarifies that while a 90-degree angle is ideal for accurate torque application, minor deviations typically result in only a 4-5 ft-lb difference, which is often within the acceptable tolerance for components like AR-15 barrel nuts. The presenter emphasizes that while not always critical for certain components, maintaining the correct angle is considered best practice.

This video demonstrates the use of a fixed ballistic barrel to test the accuracy of Sellier & Bellot 5.56mm ammunition. The setup is designed to eliminate shooter error, providing a pure measure of the ammunition's mechanical accuracy. An experienced instructor guides the viewer through the process, highlighting the importance of controlled testing environments.

Instruction from Brownells experts Steve and Caleb debunks the myth that a tight AR-15 upper-to-lower receiver fit is crucial for mechanical accuracy. They explain that accuracy is primarily determined by components within the upper receiver, such as the barrel and optic mounting. While a tighter fit may improve shooter perception and follow-up shot speed, it does not affect the inherent precision of the firearm.

This review of the LaRue Tactical MBT-2S trigger highlights its significant impact on a rifle's potential accuracy, distinguishing it from mechanical accuracy. The instructor, with extensive experience, ranks LaRue slightly above Geissele due to his understanding of Mark LaRue's manufacturing. The MBT-2S offers a light, consistent pull and a crisp, short reset, dramatically improving shooting performance compared to gritty mil-spec triggers. At $87, it represents exceptional value for a custom-grade AR-15 trigger.
