Videos tagged with AR-15 Gas System

This video provides expert guidance on selecting the correct gas block and gas tube for AR-15 builds. It details how gas system length impacts rifle performance, recoil, and reliability, emphasizing the importance of matching components to barrel diameter and desired shooting characteristics. The instructor highlights the benefits of adjustable gas blocks for fine-tuning performance and mitigating common issues like overgassing.

This video breaks down the different AR-15 gas tube lengths (Pistol, Carbine, Mid, Rifle, and Intermediate) and their impact on shooting dynamics. The presenters demonstrate how barrel length and gas system choice affect recoil, muzzle rise, and overall shooting experience, emphasizing that the 'best' system depends on the intended application and build.

This video explains the rationale behind choosing a mid-length gas system for an 18-inch barrel on AR-platform rifles, specifically addressing the Hansen model. It details how a mid-length system allows for a smaller gas port, more rifling to stabilize the projectile, and improved cycling balance compared to a rifle-length system on the same barrel length. The instructor emphasizes that a larger gas port is required for longer gas systems to compensate for reduced dwell time and less rifling engagement.

This video from The VSO Gun Channel reviews the Adams Arms complete AR-15 piston upper receiver, comparing it to traditional direct impingement (DI) systems. The instructor highlights the primary benefit of piston guns: running cleaner by venting hot gas away from the receiver. The review details the Adams Arms system's design, including its monolithic MLOK rail, adjustable gas block with a set screw for fine-tuning, and a robust piston rod mechanism. While praising its clean operation and solid construction, a minor critique is offered regarding the small size of the gas block's set screw.

This live stream features discussions on AK vs. AR platforms, handgun choices for EDC, ammunition recommendations, and AR-15 build components. The host, with law enforcement experience, shares insights on firearm reliability, practical applications, and personal preferences, emphasizing training and responsible ownership. Topics also touch on political figures and current events within the firearms community.

This video reviews the Rifle Speed Adjustable Gas Block, highlighting its high price point and unique features. The presenter details its tool-less adjustment mechanism, the requirement for a proprietary gas tube, and its effectiveness in taming an over-gassed system. While acknowledging its premium quality and adjustability, the reviewer questions its value proposition for the average shooter compared to properly gassed barrels.

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 entry details a unique prototype Direct Impingement (DI) AK variant developed by Tinck Arms, built on a Zastava M70 receiver. It highlights the conversion from a traditional AK long-stroke piston to an AR-style DI gas system, featuring a lighter bolt carrier and a free-floated barrel. The guide explains the technical modifications and potential benefits like reduced recoil and improved modularity, emphasizing its prototype status.

This Q&A session from Small Arms Solutions delves into the critical topic of gas port sizing on AR-15 and AR-10 platforms. The instructor explains how gas port diameter directly impacts the weapon's cycle of operation, leading to issues like short-stroking with insufficient gas or excessive wear and component damage with too much gas. The discussion also covers how ammunition type and gas port erosion can affect cycling, and the importance of proper gas block installation.

When running a 16-inch 5.56 barrel with a mid-length gas system and a lightweight BCG, the appropriate buffer weight depends on the barrel profile. For a government profile barrel, an 'H' (heavy) buffer is recommended. If the barrel is a heavier SOCOM profile, an H2 buffer would be more suitable. This recommendation aims to optimize the firearm's cycling and reliability.
