This video from SmythBusters investigates the common practice of mounting optics on AR-15 handguards, including bridging the receiver and handguard. Steve and Caleb from Brownells use red dot sights and LPVOs to demonstrate how this mounting method impacts accuracy, group size, and zero retention. They conduct drop tests to show zero shift and compare the performance of optics mounted on the handguard versus the receiver. The video concludes by debunking this internet myth and emphasizing the importance of proper optic mounting for reliable firearm performance.

This video provides a detailed review of AAC's 77-grain Open Tip Match ammunition (AAC556OTM1-20) for the AR-15 platform. The creator tests the ammunition across six different AR-15 barrels, meticulously recording group sizes and velocities using both Garmin Xero C1 Pro and ProChrono DLX chronographs. The analysis includes A-ZED scores for group performance context, comparisons against other ammunition loads in each barrel, and highlights any unusual findings like extreme low-velocity shots or platform variability. The content is sponsored by Jack Wolf Knives and sets the stage for a future video on lot-to-lot variations.

This video showcases the first group of shots fired from a suppressed T/C Encore rifle. The focus is on the firearm's performance, particularly with the addition of a suppressor, and the resulting accuracy from the initial firing session.

This video focuses on the critical concepts of grouping and group size for achieving consistent long-range shooting accuracy. It explains how external factors become more influential at longer distances, leading to larger groups. The description emphasizes learning the fundamentals to improve accuracy, directing viewers to sobtactical.com for the full content. The video is presented by SOB Tactical and tagged with #sobtactical, #precisionshooting, #tacticaltraining, and #shorts.

This video showcases a 21-round group and zeroing process at 25 yards, featuring a Trijicon RMR with a 3.25 MOA dot. While the specific firearm isn't explicitly named in the title or description, the focus on a red dot optic and group size suggests a pistol or carbine. The content is geared towards firearm enthusiasts interested in optics performance and basic marksmanship.

This video explores the practical application of weight sorting centerfire rifle ammunition to improve consistency and accuracy. The creator tests this theory using inexpensive bulk 5.56mm ammunition at a 100-yard range. The video details the process of weight sorting, the range tests conducted, target measurements, and insights gained from the experiment. It emphasizes that the content is for educational and entertainment purposes and was filmed in a safe, regulated environment.

This video features range time with a Ruger American Predator rifle chambered in .223 Remington. The creator tests the rifle's accuracy, reporting group sizes of 11/16" at 50 yards and 1" at 100 yards (averaging 1 3/16"). The video also includes a brief comparison to a Savage Walking Varminter, noting the Ruger performed slightly better with inexpensive ammunition on a windy day, using the same optics and rings. The creator expresses satisfaction with the rifle's performance.

This YouTube Q&A video covers a wide range of firearms topics, including the British adoption of the Besa machine gun, potential Magpul Masada/ACR upper receiver compatibility with AR-15 platforms, the unpopularity of auto-ejecting magazines, and impressive small arms development by smaller countries. It also delves into the pros and cons of en-bloc clips, the future of smaller/faster handgun cartridges, methods of measuring group size, guns with added ballast for recoil control, open-bolt/closed-bolt firing mechanisms, the future of the SIG 550 series in the US, and the potential for an ebook version of 'Chassepot to FAMAS'. Other discussions include the Dreyse rifle's suitability for the US Civil War, surprising auction prices, an incident with an EM2 rifle, the most advanced arms conceivable around 1900, thoughts on the Daewoo K2, French trials of the Madsen LMG, left-handed firearm designs, the British 4.85mm cartridge, a lunch at Rock Island Auction Co., a hypothetical weapon choice for fighting Franco in 1936, interesting firearm locking and operating systems, and which 'Forgotten Weapon' the host wishes to see back in production. The video also briefly mentions reproduction French WW1 uniforms.

This video provides a comprehensive test of three different match-grade .308 ammunition options for long-range precision shooting. The host, Joel, meticulously analyzes each round by measuring muzzle velocity with a chronograph, evaluating standard deviation, and calculating extreme spread. He then compares the accuracy of each ammunition type by measuring group sizes on paper, all through a Daniel Defense DD5V2 rifle. The video highlights sponsors Ventura Munitions, BLACKHAWK!, and Blue Alpha Gear, and encourages support through Patreon and the TFBTV Discord server.

This video investigates claims of accuracy issues with the H&K G36 rifle when heated, specifically after firing four magazines on full auto. The creators aim to empirically test how much the Point of Impact (POI) shifts and group sizes increase under heavy use. The featured rifle is an H&K G36k, acquired independently for a local police department's evaluation, not supplied or endorsed by H&K. The test was serendipitous, occurring before the widely reported accuracy concerns became public.
