This video from School of the American Rifle announces the re-availability of SOTAR BCG bore gauges, offered in two versions: one with a US-made handle and another with an imported handle. The organizer tray, made by Suppressor Tools.com, is also highlighted as a way to keep these gauges organized. The instructor emphasizes that these gauges are for checking dimensional efficiency within the bolt carrier, not for determining good or bad status.

This video demonstrates a critical quality control check for AR-15 carrier keys, specifically highlighting issues with Del-Ton components. The instructor shows how to use a Go gauge or a gas tube to verify proper fitment, revealing that a significant percentage of tested carrier keys failed to meet specifications. This inspection is vital for ensuring reliable firearm function.

This guide details the process of checking headspace on an M1 Garand after replacing the bolt. It emphasizes the importance of using go and no-go gauges to ensure the chamber dimensions are within safe operating tolerances. The video demonstrates the correct procedure, highlighting that a properly functioning Garand bolt should close on a go gauge but not on a no-go gauge, preventing potential safety issues.

This video addresses common questions regarding firearm headspace gauges, specifically focusing on Go, No-Go, and Field gauges. The description emphasizes that the content is for learning purposes and explicitly warns individuals without the necessary skills not to attempt the procedures shown. It also includes a Patreon link for viewer support.

This guide details how to check headspace on an AK47 using Go, No-Go, and Field gauges. It emphasizes proper cleaning, bolt stripping, and the correct procedure for gauge insertion to ensure firearm safety. The video highlights that a rifle closing on a Field gauge is unsafe and requires immediate attention from the manufacturer.

This YouTube video from VSO Gun Channel delves into the critical distinction between a "NO-GO" gauge and a Field Gauge, specifically in the context of 7.62x39mm ammunition. The description emphasizes VSO's role as an educational resource and a contract research and development lab, clarifying that they do not sell firearms but rather focus on objective testing and responsible gun ownership. The video likely demonstrates the practical application of these gauges to ensure firearm chamber safety and proper ammunition fit, a crucial aspect of firearm maintenance and safe operation.

This guide details a technique for testing the headspace of an AK-pattern rifle after rapid firing, as demonstrated by an expert instructor from Military Arms Channel. The process involves performing initial cold headspace checks with go and no-go gauges, followed by rapid firing to heat the weapon. The crucial step is re-testing with a no-go gauge while the firearm is hot to determine if heat expansion affects chamber dimensions enough to compromise safety. The expert emphasizes that proper firearm maintenance and immediate attention to any failed headspace test are critical for safe operation.

This guide details how to check AK headspacing using go, no-go, and field gauges, as demonstrated by experts Rob Ski and Chase Sisgold. It emphasizes proper technique, the importance of not using excessive force, and identifying signs of wear that indicate a need for gunsmith attention. Proper headspacing is crucial for safe and reliable firearm function.

This guide, presented by Larry Potterfield of MidwayUSA, details the critical process of checking headspace on an AR-15. Proper headspace is essential for safe and reliable operation. The procedure involves using specialized 'go' and 'no-go' gauges after preparing the bolt and thoroughly cleaning the chamber. Failure to achieve correct headspace can lead to malfunctions or dangerous conditions, necessitating bolt or barrel replacement.

This video explains the critical concept of firearm headspace, particularly in AK-47 rifles, defining it as the safe 'breathing room' between the bolt face and the chamber's datum. It details how to measure headspace using go, no-go, and field gauges, emphasizing the importance of not slamming the bolt onto the gauge for accurate readings. The instructor clarifies that while a no-go gauge indicates a used firearm, a field gauge signifies an unsafe condition for firing.

This video from Palmetto State Armory demonstrates the typical wear patterns expected on an AK-47's bolt and trunnion after firing approximately 1000 rounds. It highlights that minor wear and polishing on the bolt lugs and trunnion are normal during the break-in process and do not indicate a compromised rifle. The process involves using headspace gauges to track changes as rounds are fired.

This guide details how to check headspace on a bolt-action rifle, a critical gunsmithing task for ensuring safe operation. Larry Potterfield, founder of MidwayUSA, demonstrates the use of Go and No-Go gauges to measure chamber depth. Proper headspace is essential for reliable function and preventing dangerous pressure issues.
