This review of the new Stag 15 Tactical highlights its updated features and manufacturing relocation to Cheyenne, Wyoming. Key improvements include a Melonite treated barrel and bolt carrier group for enhanced durability and accuracy, a Magpul MOE stock for improved ergonomics, and a modern MLOK handguard. The mid-length gas system paired with an H buffer suggests a smooth shooting experience. The reviewer emphasizes Stag's commitment to quality and modernizing their builds.

This video provides an in-depth review of the Bravo Company USA RECCE 16 Precision rifle. The reviewer, with over 1000 rounds fired through the platform, highlights its precision-oriented design, comparing it conceptually to a modern Mk12 Holland rifle. Key features discussed include the 410 stainless steel barrel with a 1:8 twist, the 5.56 NATO match chamber, the Mark II upper receiver designed to reduce flex, and the high-quality BCM bolt carrier group. Accuracy testing with various ammunition types reveals a preference for 69-grain loads, achieving half-inch center-to-center groups. The review also covers the MCMMR handguard, BCM's staking practices, and the rifle's overall reliability and build quality, positioning it as a high-value, performance-driven AR-15.

This live Q&A session from Small Arms Solutions covers a wide range of firearms topics. The instructor discusses the internal components of bolt carrier groups, the historical quality issues with Olympic Arms, and the differences between stainless steel and chrome-lined barrels. He also touches on the manufacturing practices of various AR-15 manufacturers like DPMS, Bushmaster, and Saber Defense, the pros and cons of different buffer systems, and recommendations for AR-15 optics. The discussion extends to the military's potential adoption of new combat rifles, the reliability of DPMS firearms, and the design philosophy behind Glock's grip angle. Additionally, the instructor addresses questions about specific calibers like 6.5 Grendel and 6.8 SPC, the effectiveness of Black Hills ammunition, and the best rifle for an apocalyptic scenario.

This guide, drawing on the expertise of Brownells, details the function and selection of AR-15 buffers. It explains the components of standard, H, H2, and pistol buffers, highlighting how tungsten carbide weights in heavier buffers manage bolt carrier group speed. The guide provides specific recommendations for buffer selection based on firearm type, caliber, and operational characteristics like full-auto fire or short barrels, emphasizing their role in smoothing recoil impulse and ensuring reliable cycling in direct blowback systems.

This guide, drawing from an expert assessment by nsz85, details the critical role of AR-15 buffers in rifle function. It covers buffer weight selection based on the principle of using the heaviest buffer that ensures bolt lock-back on an empty magazine. Key concepts like dwell time, overgassing, and their impact on extraction are explained, along with the mechanical differences between standard rattling buffers and those using tungsten powder.
