This video conducts a head-to-head comparison between an FN-branded cold hammer forged chrome-lined barrel and a 14.5" Hodge Defense barrel, both built to FN specifications. The analysis includes a detailed spec rundown, inspection, borescope examination, gas system comparison, and side-by-side accuracy testing with various ammunition types including Federal GM 77gr SMK and IMI Razor Core 77gr. Rifle stability is tracked using a Mantis X10, and results are scored using the A-ZED system. The video aims to evaluate how a mil-spec FN barrel performs against a boutique-spec Hodge barrel, with the Hodge barrel showing a strong performance, particularly with premium ammunition.
This video features a comprehensive review and test of a 16-inch White Oak Armament SPR barrel after 4,000 rounds. The analysis includes bench inspection with a borescope, throat erosion gauging, and measurements of the gas block journal and barrel extension. Despite minor issues, the barrel is then tested on the range with three different ammunition types (Hornady 73gr ELD-Match, AAC 62gr FMJ, AAC 77gr SMK) for 30-shot groups at 100 yards. Shot tracking is done with a chronograph and Mantis X10, with group measurements using the Ballistic-X App. The review utilizes the A-ZED metric to assess practical accuracy against a USPSA A-zone, ultimately placing the barrel second on the creator's leaderboard.
This video features an in-depth review and accuracy test of the Palmetto State Armory JAKL-10 chambered in .308 Winchester. The reviewer performs a borescope inspection, uncovering a rough chamber and a blemish on the crown, and analyzes the impact of these defects on accuracy. The video details a shooting setup using 30-shot groups at 100 yards with four types of ammunition (PMC Bronze 147gr FMJ, AAC 168gr Sierra MatchKing, AAC 175gr Sierra MatchKing, and PMC X-TAC Match 168gr OTM), measuring mean radius, group size, velocity, standard deviation, and shooter-induced flyers using the Mantis X-10. A new A-ZED metric is introduced to assess practical long-range performance. The review also includes a comparison to a 5.56 SPR using the Applied Ballistics WEZ tool.
This video evaluates the accuracy and durability of a 16.25" Geissele Cold Hammer Forged (CHF) Barrel. The analysis includes a detailed look at specifications, borescope inspection, throat erosion and gas port measurements. A rigorous accuracy test is conducted using 30-shot groups, chronograph data, and an accelerometer to identify shooter-induced flyers. Results are broken down and compared to other tested barrels, with the introduction of a "Budget Hit Probability Calculator" for practical range estimation. The video aims to provide data-driven insights for those considering a Geissele CHF barrel or interested in in-depth barrel testing.
This video provides a review of a 16" Midlength nitride barrel from Anderson Manufacturing with a 5.56 NATO chamber and a 1/7 twist. The reviewer covers the barrel's features, conducts a borescope inspection of its interior, and then takes it to the range for accuracy testing. Three 30-shot groups were fired with different ammunition types to evaluate the barrel's performance. The reviewer expresses that while they didn't expect exceptional accuracy, the results were lower than anticipated.
This video showcases Teslong workbench borescopes and features a shop cat named Rebel. The description details how to download the Android application for the Teslong borescope, emphasizing that it's an APK download and not available on the Google Play Store. Users will need to allow untrusted application installations and may require an APK installer. The find is credited to Josh Money.
