My SHTF rifle BCM 14.5 zeroing some new defensive ammo

This video from Brownells, featuring Caleb, explores the optimal zero distances for an AR-15, primarily for competition use. It analyzes four common zero distances: 25, 36, 50, and 100 yards, detailing their impact zones on an IPSC A-zone target at various ranges. The instructor emphasizes that the 'best' zero is dependent on the intended use of the firearm and the optic employed, recommending the 100-yard zero as a versatile option for experienced shooters, while suggesting 36 or 50 yards for those using red dots or LPVOs respectively, especially for closer engagements.

This content, featuring Retired Sgt. Maj. Kyle Lamb of Viking Tactics, Inc., focuses on the practical application of the AR-15 platform within the NRA ARC Challenge. It emphasizes fundamental shooting skills such as zeroing, understanding mechanical offset, and utilizing holdovers, crucial for both new and experienced shooters. The discussion highlights how the AR platform's modularity and the ARC Challenge's structure encourage skill development and informed gear choices for all levels of firearm owners.

This video highlights critical firearm safety failures and explains the concept of 'height over bore.' It demonstrates how the difference in height between a firearm's optic and its barrel affects bullet impact, especially at close ranges. The content emphasizes the importance of understanding this principle and adhering to the four fundamental rules of gun safety to prevent accidents.

This video demonstrates a fun range day focusing on reactive target engagement with .204 Ruger and .22 Nosler calibers. Expertly handled by the speaker, the session covers shooting various targets from 25 to 100 yards, highlighting the performance of different ammunition types and rifles. The guide provides a structured approach to replicating this type of training, emphasizing safe firearm handling and understanding ballistics.

This video provides a practical demonstration of a shooting technique focused on proper rifle manipulation. The instructor highlights the use of a True North Concepts Grip Stop on a Springfield Armory Saint Victor rifle, emphasizing how it aids in achieving a solid shoulder mount for accurate shooting. The setup also features an EOTech optic and Cloud Defensive light, showcasing a modern rifle configuration.

This video challenges the notion that short-barreled AR-15s (specifically an 11.5-inch BCM) are inaccurate at distance. The instructor demonstrates grouping from various unsupported and supported positions at 140 meters, showing that acceptable combat accuracy is achievable. The content emphasizes practical application over theoretical limitations often cited by 'fuds'.

This video provides a detailed 1,000-round review of the BCM Mark 2 upper with the Raider M13 rail, highlighting its value in 2024. The presenter emphasizes its smooth shooting characteristics, reliability, and the benefits of the BCM recoil mitigation system. Various aftermarket upgrades and personal preferences, such as the Radian safety, Magpul BAD lever, and Geissele trigger, are discussed, offering insights for AR-15 builders.

This video provides an in-depth look at the BCM MK2 upper receiver and Raider handguard, highlighting its design features for enhanced rigidity, accuracy, and durability under hard use. The presenter details the suppressor-ready gas system, reinforced upper receiver, and the Raider handguard's rigid free-float platform. It also touches on the included BCM bolt carrier group and the decision-making process for choosing this upper over competitors.

This video provides an in-depth review and demonstration of a BCM AR-15 build, highlighting the performance benefits of the BCM Mark 2 recoil system. The presenter details the rifle's components, shares over 2,000 rounds of experience with zero malfunctions, and showcases its exceptionally flat shooting characteristics through live-fire drills. The video emphasizes the reliability and shootability of BCM products, particularly the Mark 2 system's ability to reduce felt recoil.

The BCM MK2 recoil mitigation system, featuring an extended rifle-length buffer tube, M16A2 buffer spring, and T2 buffer, significantly reduces felt recoil in an AR-15 platform. The system includes a new end plate with a QD sling mount and a new castle nut. The reviewer estimates a 40-50% reduction in recoil, leading to faster follow-up shots and improved target reacquisition.
