This video provides an expert assessment of the Mk18's relevance in 2026, detailing its pros and cons. The speaker, demonstrating experienced knowledge, discusses critical factors like velocity, fragmentation range, dwell time, and effective range limitations. Recommendations are made for optimizing performance and considering alternative barrel lengths for specific needs.

This video details a comprehensive 'without rule of law' or doomsday kit setup, covering gear from head to toe. It emphasizes a streamlined plate carrier, a two-piece belt system for secondary weapons and medical, and a well-stocked 48-hour assault bag. The instructor stresses tailoring gear to METTC and prioritizing reliable, functional equipment for survival scenarios.

This video provides an expert-level test of the Mk 262 Mod 1 5.56mm 77-grain OTM ammunition, famously linked to the Osama Bin Laden raid. The host, demonstrating high-level expertise, uses a Daniel Defense MK18 and DNT Zulus HD V2 scope to recreate the reported ballistics on a Ballistic Dummy Lab bust, concluding on the ammunition's extreme close-range lethality.

This video compares the accuracy and velocity of 77-grain Open Tip Match (OTM) ammunition from AAC, Phantom Defense, and IMI, tested in both 16-inch and 11.5-inch AR-15 barrels. The presenter also briefly touches on 55-grain ammunition for comparison. The testing focuses on group size and muzzle velocity, providing data points for each ammunition type across different barrel lengths.

This video details the process of zeroing the Radical Defense Mark1 Mod 1 DMR rifle equipped with a CV Life Eagle Blaze 5-25x50 first focal plane scope. The review highlights the rifle's features, including its B5 furniture and two-stage trigger, and thoroughly tests the budget-friendly scope's clarity, adjustments, and performance at 100 yards, achieving sub-MOA groups. The presenter emphasizes the bang-for-buck value of the entire setup.

This video tests the accuracy and velocity of four different AAC 5.56 ammunition loads (69gr HPBT, 69gr Sierra Match King, 77gr OTM, 77gr Sierra Match King) fired from a 16-inch Bear Creek Arsenal upper with a 1:8 twist rate. The instructor notes that the rifle has become more accurate as it has broken in. While most loads performed well, the 77gr Sierra Match King showed inconsistent results, particularly in five-shot groups.

This guide details the practical application of four popular rifle zero distances (25, 36, 50, and 100 yards) as demonstrated by American Outlaw. The expert-level instruction emphasizes how each zero affects point of aim/impact at various ranges, providing specific recommendations for different use cases, from CQB to designated marksman roles. The video highlights the importance of selecting the correct zero for your specific mission requirements.

This video debunks common myths surrounding 55-grain FMJ 5.56x45mm NATO ammunition for WROL/SHTF scenarios. The speaker, Trench Grenade, emphasizes that while 55-grain FMJ may experience increased deviation past 350 meters and is less effective in shorter barrels (under 14.5 inches) due to reduced velocity and yaw capability, it remains a viable option for home defense and general use with longer barrels (14.5 inches and above). The discussion highlights the importance of barrel length in achieving optimal projectile performance and yaw for terminal ballistics.

This video tests the ballistic resistance of SAPI side plates against various calibers including 9mm, 5.56x45mm (55 and 62 grain green tip), and 7.62x39mm. The plates, despite being older (2007 date code) and purchased at a flea market, demonstrated significant resistance, stopping all tested rounds without dangerous pass-throughs, even under multiple hits. The presenter notes their effectiveness and value for their cost.

This video explains how to understand holdovers for long-range shooting with a red dot sight on an AK platform. The instructor details how to calculate holdovers based on the reticle's MOA values and ballistic data for specific ammunition.

This video provides a 750-round update on a BCM Raider M13 upper receiver, focusing on accuracy testing with 77-grain Open Tip Match (OTM) ammunition from Palmetto State Armory and AAC. The presenter demonstrates zeroing an EOTech optic with 55-grain ammunition at 50 and 100 yards, noting the impact of not using a magnifier. The video also touches on the firearm's reliability and the use of a Springfield Saint lower receiver.

This video from Trench Grenade discusses the top four rifle rounds for SHTF and home defense scenarios, focusing on 5.56x45mm NATO. The host, an experienced shooter, breaks down the pros and cons of M193 (55gr FMJ), M855 (62gr green tip), M855A1, and 77gr OTM ammunition, offering practical advice on their effectiveness against unarmored targets, body armor, and barriers. The discussion emphasizes terminal ballistics and practical application for civilian defense.
