This video provides a detailed, step-by-step guide on assembling the BCM buffer system for an AR-15. It covers the correct installation of the buffer tube, retainer spring and pin, end plate, castle nut, buffer spring, and buffer itself. Key steps include ensuring the buffer tube is threaded correctly to retain the pin without binding and properly aligning the end plate to capture the rear takedown pin spring.
This guide, presented by Steven and Caleb from Brownells on 'Smyth Busters', demonstrates how to un-stake an AR-15 castle nut. The common myth that staking is permanent is debunked, showing that a staked nut can be removed with minimal effort using an armorers wrench. The video emphasizes that staking prevents the castle nut from vibrating loose during use and recommends replacing the endplate upon reinstallation.
This video details the installation of an AR15 buffer tube assembly on an Aero Precision lower receiver. Key steps include preparing the buffer tube, correctly installing the buffer retainer, and securely threading the buffer tube while aligning stock notches downward. The process emphasizes hand-tightening the castle nut, applying significant torque with a wrench, and the importance of staking for recoil resistance, though the staking itself is not demonstrated.
This video explores the necessity of staking an AR-15 castle nut. While essential for duty and competition rifles to prevent loosening, it's debated for casual range use where frequent stock changes occur. An alternative like the PWS ratchet system offers a non-permanent solution for those who swap parts.
This video provides a quick tip on how to install the Primary Weapon Systems (PWS) Enhanced Buffer Tube on an AR-15 pistol or carbine.
