Videos tagged with Gas Tube Alignment

This video provides a comprehensive overview of AR-15 gas blocks, explaining their critical role in the direct impingement system. It details standard block types, attachment methods (set screw vs. clamp-on), barrel diameter considerations (0.625", 0.75", 0.93"), and the importance of proper fit to avoid rail interference. The guide also covers adjustable gas blocks for tuning recoil and suppressor performance, while cautioning they add potential failure points.

This video details the diagnosis and correction of a misaligned gas tube and improperly timed barrel nut on a Colt M4A1 SOCOM carbine. The instructor demonstrates how to identify the issue by checking rail alignment and gas tube position, and explains the importance of the bolt carrier group dropping freely. The process involves disassembling the firearm, re-timing the barrel nut, and potentially using specialized tools for gas tube alignment.

This guide details the installation and alignment of an AR-15 gas system, a critical component for reliable operation. It covers selecting the correct gas block, precise alignment with the barrel's gas port using features like indexing dimples, and securing the components. Proper gas tube length and BCG engagement are also emphasized for optimal cycling. Instruction is provided by Randy from AT3 Tactical, highlighting expert knowledge in AR-15 mechanics.

This guide details essential visual inspections for AR-15 upper receivers, focusing on identifying manufacturing defects without specialized gauges. Key areas include feed ramp integrity, bolt carrier group movement, receiver symmetry, gas tube hole concentricity, barrel extension threads, and the presence of cracks. Proper inspection helps ensure reliable firearm function and longevity.

This guide details the assembly of an M16A1 upper receiver using Brownells retro components. It covers the installation of the forward assist, rear sight assembly, ejection port dust cover, barrel, and gas tube, emphasizing proper torque specifications for the barrel nut and alignment procedures for critical components. The process concludes with flash suppressor installation and a function check.
