This video features a Glenfield Marlin Model 60 rifle at the range, testing the effectiveness of several upgraded parts including an MCARBO recoil spring and ejector wire, a 3D-printed softer buffer, and a new trigger housing. The reviewer notes the rifle's reliability and accuracy with open sights, especially with good ammunition, and plans to add an optic for further accuracy improvements. The reviewer expresses a fondness for older Marlins, citing their value, minimal recoil, and good shooting performance.
This video documents a beginner's first attempt at sheet metal stamping, specifically 18-gauge mild steel. The creator was inspired by the aesthetic of the WW2 German Sturmgewehr and aimed to achieve a similar look for a universal trigger housing. The video showcases the process and the creator's satisfaction with the initial results, highlighting a learning experience in metalworking techniques.
This YouTube video, a re-upload from 2017, showcases the detailed CNC machining and assembly process of firearm trigger housings. The footage captures the transformation of raw aluminum blocks into finished components over a 17-minute duration. The video also includes subsequent steps of deburring and anodizing, offering a technical look at firearm part manufacturing, which is described as either "CNC porn" or "pure boredom" depending on viewer preference.
This video showcases an early prototype of the BFG-50A rifle, filmed in 2008 with no post-production. The description highlights unique design features, including a handguard latch mechanism and a modified trigger housing that shortened the firearm but presented engineering challenges. The footage also captures a failure to eject, attributed to potential undergassing in this pre-production model. It offers a glimpse into the development process of a specific large-caliber rifle.
