10,000 Rounds Through a JP AR-15 Barrel—Is It Cooked or Still a Laser?"

This video features an expert-level accuracy test comparing budget and high-end AR-15 platforms. Instructor Elliott Delp analyzes whether a higher price point consistently correlates with superior accuracy, using MOA measurements to quantify performance. The findings suggest that factors beyond cost, such as ammunition and shooter skill, significantly influence group sizes.

This guide details a method for comparing the velocity readings of different chronograph brands and types, including optical and Doppler radar units. The host of The Gun Dungeon demonstrates a rigorous testing procedure using both rifle and pistol calibers, highlighting that while differences exist between devices, ammunition variance is often more significant. The analysis provides actionable data for shooters seeking to understand their equipment's performance.

This video showcases a creative approach to pumpkin carving using firearms, inspired by Hickok45. The hosts demonstrate carving with a 9mm Glock 34 and an AR-15, highlighting the different effects. The grand finale features a shotgun blast and a 7.62x39mm Draco pistol, illustrating projectile impact on a pumpkin. The content emphasizes safe firearm handling and encourages viewers to engage with shooting sports.

This video demonstrates the process of zeroing an M16A2 rifle and testing the accuracy of two different ammunition types: 69-grain Federal Match and 62-grain M855 Ball. The instructor walks through establishing a 25-meter zero, performing shot groups, and then extending to 100 meters, emphasizing proper shooting technique and sight adjustments. The comparison highlights potential differences in accuracy and point of impact between match-grade and standard ball ammunition.

This video showcases a 300 BLK competition, highlighting timed runs on steel targets. The speaker, an experienced shooter, provides commentary on performance, including missed targets and split times. The content emphasizes the practical application and competitive potential of the 300 BLK cartridge in an AR-platform rifle setup.

This video compares the ballistic performance of M855 62gr FMJ and a 60gr Nosler Partition handload fired from AR-15 platforms with 10.5-inch and 16-inch barrels into Clear Ballistics gel. The instructor notes significant differences in wound channel and penetration based on barrel length and ammunition type, particularly highlighting the tumbling effect of M855 from the shorter barrel and the expansion characteristics of the Nosler Partition.

Preston Moore, demonstrating high expertise, provides an analytical assessment of a Criterion CORE series barrel after 15,000 rounds. He details significant internal wear, including throat erosion and fire cracking, using specialized tools like borescopes and erosion gauges. Despite the degradation, the barrel still produced surprisingly acceptable groups with specific ammunition, highlighting its durability and the importance of testing worn components.

This video provides an in-depth review and accuracy test of a Ballistic Advantage AR-15 barrel. The presenter, Preston Moore, details the barrel's specifications, including its Hensley profile, 16-inch length, mid-length gas system, and 1:7 twist rate. He conducts extensive live-fire testing with four different ammunition types at 100 yards, meticulously recording group sizes, velocities, and rifle stability scores using advanced equipment. The results are compared against Ballistic Advantage's sub-MOA guarantee, offering practical insights into the barrel's real-world performance.

This video provides an in-depth accuracy test of the Sons of Liberty Gunworks 16-inch SPR barrel, featuring unique polygonal rifling and a 5/8x24 thread pitch. The instructor conducts 30-shot groups with various ammunition types, meticulously recording data on velocity, rifle stability, and group size using advanced metrics like the A-ZED score. The results demonstrate exceptional accuracy, positioning the barrel favorably against competitors.

This video provides a detailed comparison of two BCM ELW (Extreme Lightweight) barrels, examining their manufacturing consistency and on-range performance. The presenter conducts thorough bench inspections, including gauging, weighing, and borescope analysis, highlighting potential manufacturing variations. Live-fire testing involves 30-shot groups at 100 yards with various ammunition types to assess accuracy, velocity, and consistency, offering insights into the practical performance of these lightweight barrels.
