This entry details the unique XR-86 custom rifle, a 1986 build by Wilfred Ellis. It masterfully combines components from an M60 (flash hider), an M14 (gas system), and an AR-15 (trigger, bolt, locking system). The AR-15 trigger is notably rotated 90 degrees, and its bolt is integrated with the M14 gas system, showcasing advanced gunsmithing.

This video from School of the American Rifle highlights critical manufacturing defects in AR-15 bolt carrier keys, specifically focusing on rough internal bores. Lead instructor demonstrates how a poorly finished carrier key can cause significant friction, premature wear on components like gas tubes, and operational issues, contrasting a problematic new Colt carrier with a well-functioning older model. The expert emphasizes the importance of a smooth bore for reliable function and longevity of expensive parts.

This guide, presented by an expert firearms instructor, details the benefits and installation of adjustable triggers for platforms like the AR-15. It covers understanding trigger mechanics, adjusting pull weight, reset, and overtravel, and highlights ideal users for these components. The instruction emphasizes safety and practical application for competition and precision shooting.

This guide, presented by School of the American Rifle, details how to identify and replace a malformed weld spring in an AR-15 Delta Ring assembly. A misaligned weld spring can cause the gas tube to be pushed off-center, leading to excessive friction or damage to the carrier key and gas tube. Replacing the faulty component ensures proper gas tube alignment and firearm reliability.

This guide details the process of diagnosing and fixing a significant rail wobble issue on a new Daniel Defense Mk18 upper receiver. The primary cause identified was a hand-tight barrel nut, compromising the stability of the RIS II rail system. The steps involve disassembly, inspection of the barrel nut, proper tightening with an armorer's wrench and torque wrench, and reassembly. This addresses a critical quality control failure that can affect firearm accuracy and reliability.

Elliott Delp showcases his favorite AR-15 build, a compact and mobile SBR emphasizing both aesthetics and functionality. The build features a Daniel Defense upper receiver known for reliability, paired with traditional A2 sights and modern accessories like a vertical foregrip and red dot optic. Live-fire demonstrations highlight its performance and manageable recoil.

Security contracting offers significant financial rewards, with daily rates potentially exceeding $1,000, and lifestyle perks like generous time off and high-quality amenities. However, it presents substantial cons, including the risk of 'lifestyle creep' due to high pay and the emotional toll of missing crucial family moments. The speaker, Ivan from Kit Badger, strongly advises having a clear exit strategy to avoid becoming a career contractor.

This project transforms a stock Ruger American .308 into a more capable precision tool. Key upgrades include a Magpul Hunter stock for improved ergonomics and a Bushnell Nitro scope for better long-range adjustments. Barrel modifications involved shortening it to 16.5 inches and threading for a Q Thunder Chicken suppressor, maintaining reasonable accuracy with match loads.

This video explains the realities of security contracting, differentiating it from mercenary work and detailing the stringent requirements for getting started. Key takeaways include the necessity of military or specialized law enforcement experience, the importance of a Statement of Work (SOW), and the often mundane nature of the job contrasted with its high risks. Networking and possessing a TS/SCI clearance are highlighted as crucial for high-paying contracts.

This video demonstrates how to paint a Glock 19 pistol for personalization and protection. Key steps include thorough masking of non-paintable areas like optics and lights, degreasing with Slip 2000 725 for adhesion, applying a sand base coat, and a matte clear coat for durability. Camouflage patterns are layered using stencils like camo netting, with a final 'dusting' to break up lines.
