This video, the first part of a four-part series, focuses on the lower receiver of a Ruger AR556. Despite audio issues preventing a reshoot, the reviewer details several problems encountered, including stiff detents, buffer spring issues, receiver extension clocking, under-torqued and unstaked castle nuts, weak hammer springs, receiver extension not engaging buffer detents correctly, notched hammers, insufficient carrier key gaps, and issues with the magazine button and catch leading to binding with PMAGs. The reviewer also notes minor cosmetic scratches. This installment appears to be an in-depth examination of the AR-15 platform's assembly and potential defects.
This YouTube video's title, "Quadruple the Spring Power!", suggests a focus on firearm modifications or enhancements, likely involving increased spring tension. The description promotes an Indiegogo campaign for "2024 shirts" ending November 10th and encourages support through Patreon and SubscribeStar. While the specific firearm is not named, the context of "spring power" strongly implies a mechanical aspect of a firearm, potentially related to recoil springs, hammer springs, or magazine springs. This could be a deep dive into a specific component's function or a comparative analysis of different spring strengths. The call to action for merchandise and support indicates a content creator's engagement with their audience.

This video details a follow-up range trip for a bobbed hammer Charter Arms Undercover revolver. The owner successfully addressed a previous issue by replacing the hammer spring, which allowed previously problematic reloads to function reliably. The successful test confirms the owner's confidence in carrying the firearm again, highlighting its readiness for personal defense.
This "Smyth Busters" episode debunks the myth that large-caliber AR-15s require heavier hammer springs. The video explains that cartridge size is irrelevant to hammer spring force and that primer hardness is the key factor. It explores how this misconception might have originated from issues with over-gassed guns or unreliable ignition with certain ammunition like 7.62x39mm. Ultimately, the video concludes that a standard AR-15 hammer spring is sufficient for most large-caliber applications, unless dealing with difficult primers.
This video focuses on the top three most common AR-15 malfunctions, offering quick tips to resolve them. Expert Caleb Savant details issues like gas block misalignment, incorrect buffer weight or spring, and improperly installed hammer springs. He explains how these problems disrupt AR-15 operation, leading to feeding, extraction, or ejection failures. The advice is relevant for both home-built and factory AR-15s, with a specific call to action for correctly installing mil-spec trigger hammer springs.
This video from Brownells features Gun Techs Steve Ostrem and Caleb Savant discussing essential spare parts for AK-47, AK-74, and other Kalashnikov-platform rifles. They highlight the importance of replacement springs (hammer, trigger, extractor, recoil) as they can lose tension over time, especially when using a sound suppressor. While other parts like firing pins and extractors are generally durable due to the AK's robust design, the video emphasizes that spare magazines are the most critical "spare part" to have on hand. The advice is practical for AK owners looking to maintain their firearms.
This video provides essential advice from Brownells Gun Techs Steve and Caleb on critical spare parts to keep for an AR-15. They highlight commonly failing components like gas rings, buffer springs, extractor springs and pins, and pivot/takedown pin springs and detents. The experts also discuss the importance of having original trigger parts as spares if an upgrade has been made. The primary reason for keeping these small parts on hand is to avoid downtime at the range due to loss during cleaning or normal wear and tear.
This YouTube video demonstrates a modification to the trigger (hammer) spring of a Rex Zero 1 handgun. The described modification aims to improve the firearm's reliability, particularly when using a light competition trigger spring. The video also promotes the creator's Patreon community and merchandise store.
This video provides a detailed, multi-chapter guide to installing, gauging, fitting, and tuning three different AR-15 fire control groups (FCGs): the Geissele SSA-E, LaRue MBT, and a factory type. It covers essential steps like spring inspection, pin removal and inspection, de-magnetizing, de-greasing, and precise gauging of FCG components and lower receiver bores. The video also touches upon receiver bore lapping, selector bore gauging, and pistol grip installation issues. While focusing on FCGs, it explicitly states it does not cover anti-rotation pins, lightened hammer springs, or cassette triggers. The content is highly technical and geared towards AR-15 builders and enthusiasts seeking to understand and optimize their trigger systems.
