This video provides an unboxing and installation guide for the AntiMatter Scopeswitch, a scope mount designed to allow magnification adjustments without breaking the shooting stance. It highlights the mount's construction using 7075 T6 aluminum and 4140 nitrided steel, emphasizing its strength, low weight, and practical application for dynamic shooting. The video covers hardware details, installation steps including torque tips and optic alignment, and an on-gun demonstration of its functionality. Fitment notes address the 1.93" optical centerline, compatibility with 10.5" barrels (and recommendations for 5.56), and clearance with plate carriers. The Scopeswitch aims to improve target focus and support-hand positioning during magnification changes, making it suitable for compact rifles and modern tactical setups.
This "Gun Of The Week" feature from American Rifleman examines the CVA Cascade Long Range Hunter (LRH). The video details its features, designed for extended-range shooting and hunting. It highlights the rifle's turn-bolt action, 4140 steel receiver, three-lug bolt with a tactical knob, and thicker, fluted barrels with a radial muzzle brake and 5/8x24 TPI threading. The stock is rigid with an adjustable cheekpiece and length of pull, and the receiver sports a one-piece Picatinny rail with a 20-m.o.a. tilt. The rifle is chambered in popular calibers like .308 Win., 6.5 mm Creedmoor, and .300 Win. Mag., and comes with a three-round detachable box magazine. Testers found it to be a potent choice for long-range work with smooth operation and fast follow-up shots, noting its suitability for a wide range of shooters.
This video highlights a small but significant improvement from SOLGW (Sons of Liberty Gun Works) – a new grip screw for their AR-15 platform. The screw features a combo head compatible with both 3/16" hex drivers and flathead drivers, is constructed from durable 4140 Steel, and finished with a Black Oxide coating for corrosion resistance. SOLGW emphasizes their commitment to continuous fine-tuning and readily available parts, stating this screw will be included in all their firearms, lower parts kits, and offered to OEM partners. The focus is on enhancing an already functional platform with quality components.
This video introduces the new Bullet Proof® Adjustable Lo-Profile AR-15 Gas System from Wilson Combat, presented by Paul Levy of Brownells. The system features a low-profile gas block made of 4140 steel with an integrated stainless steel gas tube. Its key feature is a slot-head screw allowing adjustment of gas flow through 16 positive-click settings, enabling users to optimize for different ammunition. The self-cleaning mechanism scrapes out carbon fouling with each adjustment. Setscrews secure the block to pre-dimpled barrels, and the straight gas tube simplifies installation. The system is available with various gas tube lengths and for different barrel diameters.
This video, Part 2 of a home shop rifling series, explains the critical importance of heat treating a barrel *before* rifling. The creator details how the necessary hardness (Rc 28-32 for 4140/4150 steel) impacts the rifling process, requiring more force to swage the rifling but ultimately resulting in a stronger, tougher barrel. Key reasons for pre-heat treatment include preventing the rifling button from picking up steel and preserving the precise bore dimensions and straightness during the high-temperature heat treating and quenching process. Post-rifling heat treatment would compromise the strain-hardened bore surface, which significantly reduces friction and enhances wear resistance.
This video from Brownells features Gun Tech Steve Ostrem demonstrating the installation of a Wilson Combat Full Size Guide Rod for Beretta 92/96 pistols.
