How To Install Your Safety And Grip On Your AR15 Lower Reciever (Radian Talon Ambi | Magpul K2-XL)

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 YouTube Short, titled "Install this RIGHT!!!", focuses on a firearm component installation, as indicated by the title and the promotional link for 'ALL MY GEAR + EXCLUSIVE DISCOUNTS'. While the specific firearm or component is not explicitly named, the context strongly suggests a technical aspect of firearm ownership or modification. The video likely demonstrates a correct installation process, aiming to guide viewers through a potentially complex task. The use of "#shorts" implies a concise, fast-paced video format common on the platform.

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.

This video provides a detailed guide on installing a Trijicon RCR red dot sight onto a Glock 17, specifically addressing MOS slides. It emphasizes safety checks, proper disassembly, and the correct use of adapter plates and torque specifications (13 inch-pounds) for secure mounting. The guide also covers reassembly and a final visual check of the optic.

This guide details the installation of a Leupold Delta Point Pro red dot sight on a Glock 17 MOS. It emphasizes proper disassembly, using specific adapter plates like Forward Controls, and applying thread locker with precise torque values (13 inch-lbs for the plate, 25 inch-lbs for the optic). The process also includes installing a rear iron sight for co-witnessing capabilities.

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 video demonstrates the ghost loading technique for the Beretta 1301 Tactical (Mod 1 & 2) to achieve a 9-round capacity (1+1+7). It details the process of loading the magazine tube, manipulating the bolt release, and carefully placing an extra round onto the lifter, especially with the Pro Lifter accessory. The technique allows for a faster follow-up shot by having a round already positioned for chambering.
