The Tactical Orca Handguard

This video demonstrates the functionality of the Lima Six belt-fed upper receiver, compatible with AR-15/M16 platforms, firing 5.56x45mm NATO or .223 Remington ammunition. Expert insights from Sudo Solutions showcase manual belt loading, sustained full-auto fire, controlled bursts, and the use of specialized gear like 3M Peltor headsets and Mechanix Wear gloves. The demonstration highlights the DIY firearm community's capabilities in creating complex, functional firearm components.

This video details observations from a 600-round test of two 'Orca' 3D-printed firearms, one in PLA Plus and one in Carbon Fiber Nylon. Key takeaways include the failure susceptibility of polycarbonate clips, the thermal limitations of PLA Plus leading to malfunctions, and interesting insights into brass ejection dynamics.

This video showcases the 'Baby Orca,' a shorter variant of the Orca firearm platform, designed for pistol-length barrels. It highlights new handguard and pistol stabilizing brace components introduced in a recent update. The build features an FDE aesthetic with a Primary Arms 3x Micro Prism optic and 3D printed components, demonstrating a unique look while discussing potential material limitations under heavy use.

This video details a stress test on a 3D printed firearm, the Orca, using a push-up method to simulate extreme forces. The test reveals the material limitations and structural weak points of the printed components, particularly highlighting the difference in performance between polycarbonate and carbon fiber nylon clips. The instructor demonstrates how to apply stress and analyzes the failure points, offering insights into the durability of 3D printed firearm designs.

This review tests the GoGoGo laser rangefinder, assessing its accuracy and practical range for various applications. While performing well on reflective targets up to 300 yards with +/- a few yards of variation, its effectiveness diminishes significantly beyond 400 yards, especially on non-reflective or obstructed surfaces. The reviewer notes its precision to the tenth of a yard is misleading given its +/- one-yard accuracy, suggesting it's better suited for golfing or zeroing rifles rather than extended long-range shooting.

The Ounce Pistol is demonstrated for its rapid-fire capabilities on steel targets. The video details its unique loading procedure via a side door for its 10+1 capacity .22 LR internal magazine and its folding mechanism for concealment and deployment. Expert handling showcases the firearm's specific mechanical nuances.

This guide details the installation and modification of the Super Safety, an active trigger reset system for the AR-15 platform, developed by Hoffman Tactical. It covers the necessary trigger modifications, component installation, and function checks. The system utilizes a push-button interface and offers a unique 'Active Reset' position for significantly faster trigger resets, as explained by the designer.

This guide details the process of 3D printing an AR-15 lower receiver using Carbon Fiber Nylon, based on expert instruction from Hoffman Tactical. It covers essential filament preparation, specific printer hardware requirements, critical print settings, advanced slicing techniques for warp prevention, and post-processing steps. The instruction emphasizes the importance of material science knowledge for successful and durable firearm component printing.

The Altor pistol is a unique semi-automatic, long-stroke recoil-operated firearm chambered in .22 Long Rifle, distinguishing itself from typical blowback-operated .22 caliber handguns. It features a 10-round fixed magazine located on top of the receiver, making its internal mechanics particularly fascinating for firearm enthusiasts.
