Forward Control Designs BCG Physical (Second FCD Physical)

This video provides an in-depth look at the Sons of Liberty Gun Works MK1 Carbine, specifically highlighting its configuration as an 'other' firearm to comply with New Jersey's strict firearm laws. The presenter details the components that make this build legal in the state, including the use of a pistol brace and vertical grip, and discusses the firearm's premium features and accessories.

This video provides an in-depth inspection of a Forward Control Designs (FCD) Bolt Carrier Group (BCG) with an MP3 coating. The instructor highlights the smooth finish, robust staking, and specific component details like the extractor spring and firing pin protrusion. The review emphasizes the importance of proper lubrication and identifies minor operational wear as normal, not defects.

This review of the Sharps XPB Bolt Carrier Group highlights its Diamond-Like Carbon (DLC) coating and S7 tool steel construction. After approximately 1000 rounds with minimal lubrication and cleaning, the BCG demonstrated impressive reliability, even with steel-cased ammunition. The reviewer notes the tapered bolt lugs as a potential feature aiding in locking under adverse conditions.

This video provides an abbreviated autopsy of a KAK Industries Milspec Bolt Carrier Group (BCG), focusing on a critical ejector issue. The instructor demonstrates how the ejector on the KAK BCG fails to collapse flush with the bolt face, indicating a manufacturing defect. A comparison with a BCM BCG highlights the expected functionality, where the ejector recesses below the bolt face.

This video reviews several new firearm and accessory releases, evaluating them as 'cops' or 'flops'. It covers new pistols from Bersa, Sig Sauer, Rossi, Dura, Tesor, OA Defense, and Staccato, along with a unique rifle from Big Horn Armory. Accessory reviews include a Radian suppressor, Forward Control Designs/Centurion Arms BCG, B5 and Magpul stocks, and Holosun optics.

This comprehensive physical inspection of the Forward Control Designs (SBCG) Bolt Carrier Group highlights its robust construction and attention to detail. The review covers critical checks including gas ring tension, firing pin protrusion, extractor function, bolt tail and carrier bore gauging, and headspace. The use of Aux Ox carrier key screws and Psionics staking method are noted for their security. A borescope examination reveals a very smooth internal finish, particularly in the gas ring and bolt tail runs, indicating high manufacturing quality. The reviewer concludes with a highly positive assessment, noting the BCG passed all checks with flying colors.

This guide details the process of diagnosing and repairing an owner-induced feeding problem in an AR-15 upper receiver, specifically addressing a burr on the barrel extension's feed ramp. Expert gunsmith Chad Albrecht demonstrates meticulous inspection, burr removal, and polishing techniques to restore reliable feeding. The video emphasizes that such modifications, while often overlooked, are valid solutions for specific AR-15 malfunctions.

This guide details a diagnostic technique for AR-15 bolt carrier groups, focusing on efficiency rather than simple pass/fail. Developed by Chad Albrecht of School of the American Rifle, it uses custom gauges and cutaway components to illustrate gas dynamics, critical seals, and potential failure points like gas leaks. This advanced method helps troubleshoot functionality issues and understand the nuances of the AR-15's internal gas system.

This video provides a critical, expert-level inspection of a problematic AR-15 Bolt Carrier Group (BCG) by Chad Albrecht of School of the American Rifle. The analysis details numerous manufacturing defects, including an undersized bolt tail, excessive firing pin protrusion, oversized firing pin and cam pin holes, and a failing headspace check. The content highlights the importance of precision gauging in identifying critical failure points that impact rifle reliability and safety.

This guide details a specialized technique for swapping an AR-15 rear takedown pin without requiring a full disassembly. It leverages insights from Chad Albrecht of School of the American Rifle, emphasizing the use of a modified 1/16 inch Allen wrench or a specialized tool to manage the detent. This method is particularly useful for AR-15 variants with collapsible stocks, offering a more efficient approach to maintenance.
