This comprehensive inspection of multiple Smith & Wesson M&P 15 Sport II rifles reveals a range of manufacturing and assembly issues. The video details checks for bolt lock, magazine release function, magazine well dimensions, selector engagement, forward assist operation, muzzle device alignment, receiver extension alignment, rail screw torque, takedown pin bores, gas block screw torque, barrel extension alignment, buffer spring length and compression, gas port alignment, headspace, trigger pull weight, castle nut torque, and carrier key alignment. Several firearms exhibited problems including sticky magazine releases, tight magazine wells, misaligned muzzle devices, clocked receiver extensions, undertorqued rail screws, loose gas block screws, short buffer springs, and loose castle nuts.

This video details the significant financial and logistical burdens of obtaining concealed carry permits across multiple states. The School of the American Rifle hosts explain their $12,804.63 expenditure for permits covering 46 states and D.C., highlighting the complex, state-specific requirements and the impact on Second Amendment rights. They discuss dropped permits due to changing laws and the challenges faced by non-residents.

This guide details the installation of an AR-15 buffer tube using the LAW Tactical Alignment Tool (LAT) in conjunction with a Geissele Reaction Block. Expert instruction from the School of the American Rifle demonstrates how to achieve perfect alignment of the receiver extension with the lower receiver, crucial for proper function and preventing common assembly errors. The process involves securing the components, torquing the castle nut to 38-42 foot-pounds, and ensuring a reliable build.

This video from School of the American Rifle serves as a teaser for an upcoming multi-part "Secret Shopper" review series focusing on the Smith & Wesson M&P 15 Sport III. The instructor, demonstrating expert authority, outlines the detailed testing process, which includes acquiring replacement parts, and announces the series will begin the following week, following a similar format to their previous Ruger series. Viewers are encouraged to stay tuned for the comprehensive evaluation.

This expert guide from the School of the American Rifle details how to identify and address rough carrier key bores in AR-15 bolt carrier groups. The instructor, demonstrating expert knowledge, explains how these manufacturing defects, particularly on Colt components, can lead to premature wear on the gas tube and reduced reliability. Solutions involve replacing the defective carrier key to ensure smooth operation and longevity of the firearm.

This expert guide from School of the American Rifle details how to identify and replace a malformed weld spring in an AR-15's delta ring assembly. A misaligned weld spring can cause gas tube issues, leading to potential component damage. The video provides a clear visual comparison and step-by-step instructions for replacement, emphasizing proper alignment for optimal function.

This guide details the process of staking AR-15 carrier key screws, a critical step for preventing loosening under operational stress. It covers historical staking methods, modern techniques like OCKS, and specific torque values for different generations. The instruction emphasizes the importance of proper staking for reliability, drawing on historical military technical manuals.

This guide details the use of the Obsidian Arms Bolt Assembly/Disassembly Tool for AR-15, AR-10, and SR-25 platforms. The tool features dual knockout holes, beneficial for stubborn or damaged roll pins, unlike single-hole designs. It includes a roll pin holder and punch. The video emphasizes using a stable wood bench block for striking and a flat-face punch for final pin seating to prevent damage. Instruction is provided by Chad Albrecht, a recognized expert in AR technical maintenance.

This guide details how to inspect an AR-15 Bolt Carrier Group (BCG) for critical defects, specifically peening marks on the carrier rails. Instruction from School of the American Rifle highlights how improper peening can lead to significant damage to the upper receiver. Proper inspection is crucial for ensuring BCG longevity and firearm safety.

This guide details a crucial maintenance tip for the Smith & Wesson M&P 15-22, as demonstrated by Chad Albrecht from the School of the American Rifle. The video addresses a common issue where cleaning tools can damage the rifle's ejector assembly. By applying a simple protective sleeve, users can prevent damage to both the ejector and their cleaning equipment, avoiding costly repairs or part replacements from Smith & Wesson.

This video is a deeply personal and emotional tribute to a beloved pet, Rebel Cat, who passed away from kidney failure. The creator expresses profound sadness and gratitude to their audience for their love and support of Rebel Cat. The focus is entirely on the loss of the pet and the impact it has had on the creator and the community.

This video provides an abbreviated autopsy of an Anderson Manufacturing Bolt Carrier Group (BCG) that experienced a unique failure: a sheared lug near the ejector after only 150 rounds. The instructor notes that typical lug failures occur near the extractor due to higher load. While the carrier key screws passed a breakaway test, the carrier key itself leaked, indicating poor efficiency. The instructor emphasizes checking all firearm components regardless of manufacturer.
