Videos tagged with Barrel Harmonics

The panel discusses the relevance of barrel harmonics in firearm accuracy, suggesting it's often overrated for the average shooter. They argue that factors like insufficient practice and ammunition quality have a greater impact on accuracy than barrel harmonics. While acknowledging harmonics exist, they believe their effect is exaggerated, especially when comparing models like the Glock 45 and Glock 19.

Instruction from USPSA Grandmaster Mark Smith on optimizing rifle setups, emphasizing practical performance over internet trends. Key takeaways include prioritizing barrel precision over longevity for SPRs, understanding gas porting's importance, selecting robust rails to prevent POI shift, and optimizing controls and mounting for stability and ease of use. Smith advocates for gear that enhances shooter performance through intentional, data-driven choices.

This guide explains the concept of free-floating barrels in AR-15 platforms, drawing on insights from GUNBROS. It details how free-float barrels, unlike traditional designs, do not contact the handguard, which is crucial for maintaining accuracy by preventing point-of-impact shifts caused by external pressure. The explanation highlights the mechanical benefits for precision shooting.

This video reviews the Munitions Works Valkyrie DMR in 6.5 Creedmoor, focusing on its performance at 1,000 yards. The review delves into accuracy testing, highlighting how gas block pinning can affect barrel harmonics and group sizes. It also discusses the reliability of AR-10 platforms, particularly in 6.5 Creedmoor, and compares it to other large-frame systems.

This expert guide details how to test the impact of a suppressor on rifle accuracy. It covers methodology for 100 and 200-yard tests, emphasizing the importance of observing point of impact shifts and maintaining group sizes. The instruction highlights that while suppressors may not inherently increase accuracy, they significantly improve the shooting experience by reducing recoil and noise, though re-zeroing is often necessary.

This video reviews the PSA Sabre Super SASS rifle, focusing on its barrel and accuracy. Key features include a Faxon 308 barrel with a 1:10 twist rate and 5R rifling, an adjustable gas block, and a unique compensator designed to manage barrel harmonics. Accuracy testing with various ammunition types yielded results around 1.5 to 2 MOA, with potential for sub-MOA with hand-loaded ammunition.

This guide details the proper procedure for zeroing a rifle for combat engagements. It emphasizes correct optic mounting, grouping to confirm fundamentals, understanding bullet drop compensators, and choosing between a 25-meter or 50-meter zero based on expected engagement distances. The instructor stresses the importance of confirming the zero at range and avoiding common mistakes like resting the barrel on supports.

This guide details the installation of the 'Muzzle Squeezer' prototype, a device designed to improve rifle accuracy by mechanically dampening barrel vibrations. The process involves precise placement of internal components and calibrated tightening using gauge pins. The inventor, Fritz, emphasizes the importance of correct installation for optimal performance, noting its effectiveness on standard hunting rifles but limitations on high-end precision platforms.

This video features Joe Towers from Helix 6 Precision discussing their innovative carbon fiber rifle barrels. The discussion highlights the proprietary carbon fiber application process, the 70% carbon/30% resin ratio for superior heat dissipation and rigidity, and the significant weight reduction compared to traditional steel barrels. The conversation also touches on the impact of barrel harmonics, the ability to cut barrels to custom lengths, and the impressive accuracy achieved with Helix 6 barrels across various calibers and platforms, from bolt-action rifles to AR-style firearms.

This review of the LWRC M6A1G highlights its development as a piston-driven alternative to the M4 and HK416. While acknowledging the product's quality, the reviewer notes potential downsides of piston systems like carrier tilt and increased weight. The M6A1G's non-adjustable piston system is praised for its efficient gas bleeding, performing well suppressed and unsuppressed. However, the older quad-rail handguard design limits modern accessory mounting, and parts availability for the piston system may become an issue.

This guide details common AR-15/AR-10 build mistakes and their solutions, as explained by Steve and Caleb from Brownells. Key areas covered include preventing accessory screw interference with the gas block, ensuring proper gas block alignment, adhering to the 40 ft-lbs torque spec for castle nuts, avoiding over-lapping upper receivers during lapping, and correct buffer tube installation depth. Following these steps ensures reliable function and accuracy.

This discussion between Joe of Steeling Wood Outdoors and The Yankee Marshal delves into the debate surrounding rifle barrel cleaning and its impact on accuracy. While Joe advocates for cleaning between shots for consistent groups, The Yankee Marshal argues that for most shooters, firearm reliability and function outweigh marginal accuracy gains, especially in self-defense scenarios. The conversation highlights the concept of fouling shots and the potential for barrel harmonics to be affected by cleaning intervals.
