This review of the HK MR556 A4 highlights its performance as a civilian-accessible variant of the HK 416. The rifle is praised for its smooth shooting, minimal gas in the face, and impressive accuracy, achieving sub-MOA at 100 yards. Key differences from the 416 include a non-chrome-lined barrel and the absence of a full-auto bolt carrier. Downsides noted are its weight, price, and the stock, though the gas system offers extensive adjustability.

This video details the development of a compact, folding rifle project, codenamed 'ATF'. The team discusses the selection of the 6mm ARC cartridge for short barrels, load optimization, custom bolt work, and the engineering challenges of integrating a folding stock. The project emphasizes rapid prototyping and iterative design, drawing on extensive experience to create a highly compact and capable firearm system.

This video demonstrates a DIY method for installing a custom-fit front sight on a CO2 gun using a salvaged rifle sight and JB Weld. The process involves precisely recutting the sight's contour to match the barrel diameter using a milling machine and endmill, followed by secure attachment with JB Weld. The instructor highlights the importance of accurate measurement and machining for a proper fit, even on a less expensive firearm.

This review of the Aero Precision Solus bolt-action rifle highlights its strong build quality, scoring a 5/5. Ergonomics are rated 4.5/5, with praise for adjustability but a minor critique on the cheekpiece width. Features earn a 4/5, noting the included TriggerTech trigger but lack of a muzzle brake. Practical accuracy is exceptional, achieving sub-MOA groups with factory ammunition, earning a 5/5. Value is rated 4.5/5, considering its MSRP of $2150.

This video provides an after-action review of the Competition Dynamics Team Safari match, highlighting key gear and technique adjustments for field precision rifle shooting. The speaker emphasizes the need to transition from PRS-style gear, like heavy barricade bags and chassis systems, to lighter, more adaptable equipment suitable for natural terrain and hiking. Key takeaways include optimizing rifle weight, selecting versatile bipods and tripods, and streamlining loadouts to reduce carrying burden, while also discussing the reduced utility of environmental data tools in fast-paced competitions.

This video from Banana Ballistics explains that while traditionally scopes are mounted as low as possible, a higher scope mount can offer advantages. A higher scope mount requires less elevation adjustment for longer range shots, saving valuable turret clicks. The video details how scope height affects bullet drop compensation and discusses factors like objective lens size and barrel contour that may necessitate higher mounts. Drawbacks include potential loss of a consistent cheek weld on non-adjustable stocks and increased snagging potential in brush.

This video provides an in-depth look at the Noveske manufacturing process, highlighting the meticulous steps involved in creating their rifles. The tour emphasizes the attention to detail from raw materials to finished products, including barrel contouring, chambering, and quality control measures like headspace gauging. The presenter expresses significant admiration for the operation's efficiency and the dedication of the Noveske team to upholding the founder's vision.

This video from Brownells, presented by a technical representative, details various rifle barrel profiles and their impact on performance. It explains how lighter contours are better for carrying, while heavier ones improve accuracy and heat resistance during sustained fire. Specific profiles like the M16A1, HBAR, Ultra Bull, fluted, and carbon fiber barrels are discussed with their intended applications.

This guide details how rifle weight critically impacts the performance and shootability of safari rifles. It emphasizes that total weight includes the rifle, scope, and ammunition, and must be balanced against carrying comfort and recoil management, especially for heavy calibers like the .375 H&H Magnum. Expert instruction covers component weight contributions and provides specific weight recommendations for various calibers.
