This video showcases a comprehensive build of a custom 6.5 Creedmoor bolt-action rifle by Caleb and Alex at Brownells. The build utilizes a Zermatt Origin action and a Proof Research barrel, assembled within a KRG chassis. Key stages covered include trigger installation, headspace checking, chassis mounting, and final assembly, making it a detailed guide for a first-time bolt-action rifle builder.
This video, part 2 of a 4-part series, focuses on the Bolt Carrier Groups (BCG) of a Ruger AR556. Despite audio issues that prevented reshooting, the analysis details several mechanical problems found within the BCG. These include misaligned carrier keys, issues with YFS carrier key screws, rough runs in the carrier for the bolt tail and support, and inefficient gas ring runs. The bolt itself exhibits magnetization, damaged tails, and undersized firing pin runs, leading to sticky firing pins and potential headspace issues. The video also previews a forthcoming discussion on carrier binding with PMags in part 3.
This video, part 2 of a bolt action rifle build series from Brownells, details the assembly process. Host Caleb installs a Proof Research barrel on a 6.5 Creedmoor Zermatt Origin style action, utilizing specialized tools like the Short Action Custom Barrel Vise and an action wrench. The segment covers barrel installation nuances, including different types like the Savage small shank with a barrel nut, torque application, headspace checks, and alignment. It also walks through installing a Timney trigger and fitting a muzzle device before dropping the barreled action into an MDT HNT 26 chassis. The emphasis is on precision for building a reliable and accurate bolt action rifle.
This video by Forgotten Weapons explains the concept of "headspace" in firearms, detailing what it is, why it's important, and the potential consequences of incorrect headspace. It covers how headspace allows for manufacturing tolerances in both firearms and ammunition, but too much or too little can lead to extraction issues, poor accuracy, case head separations, and even catastrophic failures ("kabooms"). The video also references other specific firearms like a Krinkov and a Turkish "Enfauser", and features a prototype rifle that operates based on headspace. It's aimed at educating firearm enthusiasts about a fundamental aspect of gun mechanics.
This video from Smyth Busters addresses the common question of whether an AR-15's headspace can be fixed. The hosts explain that while technically possible, correcting excessive or short headspace in an AR-15 is often cost-prohibitive for the average shooter, typically requiring specialized gunsmithing tools and expertise. For most users, the most practical solution to a headspace issue is replacing the barrel. The video also links to related content about mixing and matching bolt-carrier groups and a basic explanation of headspace.
This video addresses the common question of whether AR-15 bolt-carrier groups (BCGs) can be mixed and matched. The hosts explain that due to standardized manufacturing, most BCGs will fit an AR-15. However, they emphasize the critical importance of checking headspace using a NO-GO gauge after swapping a BCG. They caution that even if a spare BCG fits initially, significant barrel extension wear from prolonged use with another BCG can alter headspace, requiring re-evaluation. The video debunks the myth that mixing BCGs is always problematic, provided proper headspace checks are performed.
This video focuses on crucial headspace elements within a firearm's frame, specifically highlighting the importance of the 'datum' and the 'abutment' where the bolt face makes contact. The creator emphasizes that these two areas are critical for proper function, while other parts, including the bolt face itself, have some allowable play due to factors like dirt and operational wear. The content suggests a technical discussion about firearm mechanics and tolerances.
This video, titled "Questions, Answered #7.....Headspace," aims to explain the concept of firearm headspace. The description emphasizes that the content demonstrates what is necessary to learn rather than serving as a tutorial, and strongly advises against attempting any procedures without possessing the required skills. The creator also includes a Patreon link for support.
This video showcases a 7.62x54R Mosin action being tested on a stand. The description emphasizes that the content is for educational purposes and not a tutorial, warning viewers against attempting such procedures without the necessary skills. It features a strong disclaimer about safety and skill requirements. The title also humorously references a common Soviet sentiment: "Nyet! Weapon is fine!". The music used is titled "7.62x54r Sound of Soviets".
This video from Brownells aims to educate new and experienced firearm enthusiasts on fundamental cartridge terminology. Firearm Support Technician Caleb Savant breaks down the components of a loaded cartridge, including the bullet, case, primer, and powder. He explains different bullet types like boattail and flat base, and describes the ogive. The video details various case varieties such as straight-wall and bottleneck, and further categorizes cases by their rim type: rimmed, non-rimmed, recessed-rimmed, and belted. Headspace is also explained in relation to how different case types interact with the firearm's chamber. The content is geared towards improving understanding for those new to firearms or those seeking clarification on these technical terms.
This video demonstrates the easy installation of an International Barrels pre-fit precision rifle barrel on a Savage bolt-action rifle. The presenter, Caleb Savant from Brownells, highlights the pre-cut chambers and simple barrel nut system, emphasizing that no expensive tools are required. The process includes setting headspace using GO and NO GO gauges and torquing the barrel nut to under 50 inch-lbs. The video is aimed at rifle owners looking for a straightforward barrel upgrade for Savage, Remington 700, and Tikka actions.
This video from Iraqveteran8888 focuses on "Headspace," a critical firearm term. While the description is brief, it highlights the educational nature of the content, likely explaining what headspace is, its importance in firearm function, and potential issues related to it. Links to their educational institute (SDI), Amazon store, Patreon, USCCA, and website suggest a comprehensive approach to firearm knowledge and community engagement. The video is intended for documentary, educational, and entertainment purposes, emphasizing safe practices on approved ranges.
