How to Select a Gun Vise and What to Look For Presented by Larry Potterfield | MidwayUSA Gunsmithing

This guide details how to address a seized AR-15 upper receiver, a common issue exacerbated by suppressor use and infrequent cleaning. The instructor, with extensive firearms experience, demonstrates a multi-stage approach starting with penetrating oils and progressing to more aggressive chemical cleaners when initial methods fail. The video emphasizes understanding dwell time and the effects of carbon buildup, offering practical solutions for a problem that can render a firearm inoperable.

This guide details the process of replacing the stock on a Mauser 98 action, a common modification for sporterizing these rifles. It emphasizes that changing stocks and even barrels (e.g., to .30-06) is a straightforward process, debunking claims that older military surplus rifles cannot be modernized. The process involves removing action screws, fitting the barreled action into a new stock or chassis, and re-securing it.

This guide details how to improve the reliability of a Bear Creek Arsenal Bolt Action AR upper. The process involves thorough cleaning, lubrication, and a crucial step of buffing the bolt lugs to ensure smooth operation. Removing the buffer and recoil spring is also recommended for this specific bolt-action configuration. The video also showcases the integration of a Discovery Optics ED-LHT 3-15x50 scope for enhanced precision shooting.

This video demonstrates the installation of a Rise Armament Rev 535 drop-in trigger into an AR-15 platform rifle. The process involves removing existing pins, carefully aligning the new trigger assembly, and reinserting the pins. The speaker emphasizes ensuring the plate goes through the bottom of the receiver first and rocking the assembly under the safety selector. The goal is to achieve a fast installation, with the current top score being just under eight seconds.

This guide details the disassembly process for the gas trap variant of the M1 Garand, highlighting its differences from the later, more common models. It involves removing the bolt and operating rod first, then a specific screw to release the gas trap, followed by the sight block, before the gas trap assembly can be rotated off. This early design proved less reliable than the later gas piston system.

This guide details the process of lapping an AR-15 receiver to ensure proper barrel alignment for improved long-range accuracy. Instructor Stephen Caleb from Brownells explains that receiver faces can be slightly out of alignment, leading to barrel runout. The process involves using a specialized lapping fixture and aluminum oxide lapping compound with a drill to create a perfectly flat receiver face. This ensures the barrel seats flush and square, critical for precision shooting beyond 500 yards.

This guide details a high-speed Cowboy Action Shooting stage, demonstrating expert transitions between a lever-action rifle, dual single-action revolvers, and a side-by-side shotgun. It highlights efficient manual shotgun reloading techniques from a belt carrier, showcasing advanced proficiency in competitive shooting disciplines. The video emphasizes speed and accuracy across multiple firearm types.

This video provides an expert-level demonstration of the Mosin-Nagant M91/30 PU Sniper rifle. It covers visual inspection, the proper loading procedure for 7.62x54R ammunition, and live fire at an outdoor range, showcasing bolt manipulation and recoil control. The demonstration is presented in a silent, ASMR-style format by an authoritative demonstrator.

This guide details the complex process of reboring a Winchester 1885 Low Wall rifle from .32 Rimfire to .357 Magnum, addressing a pitted bore. Expert gunsmith Larry Potterfield demonstrates disassembly, barrel removal, specialized reboring at Delta Gun Shop, chambering, crowning, action conversion, and final marking/finishing. The process highlights advanced machining techniques and specialized tools required for such a conversion.

This guide details the cycle of operation for the Winchester Model 12 shotgun, as explained by Larry Potterfield of MidwayUSA using a cutaway model. It covers loading, safety engagement, firing, extraction, and chambering. The explanation highlights the hammerless pump-action design and internal component interactions, offering valuable insights for gunsmithing and understanding firearm mechanics.
