This review of the Rock River Arms LAR-BT3 16-inch .308 rifle highlights its construction and performance. The rifle features a billet upper and lower receiver, a 16-inch stainless steel, cryogenically treated heavy barrel with a 1:10 twist, and a 13-inch M-LOK free-float handguard. The reviewer notes the mid-length gas system and SR-25 pattern magazine compatibility. A key point of discussion is the buffer system, which uses a commercial-type buffer and a shorter receiver extension, potentially leading to increased recoil and issues when suppressed without modification. Accuracy was reported at 1.3 MOA with Black Hills 175gr OTM ammunition.

This video from InRangeTV features a deep dive into firearm barrel technology with Faxon. Topics covered include the determination and manufacturing of twist rates, their impact on bullet stability for various calibers, and the practical implications of different twist rates (e.g., 55 grain bullets in a 1/7 twist). The discussion then moves to stress relieving techniques, including thermal and cryogenic treatments, and what to look for in a properly stress-relieved barrel. The video also touches on historical barrel quality, lead lapping, the concept and necessity of barrel break-in for different shooter types (average vs. bench rest competitors), and the impact of gas port size and location on rifle function.

This review of the SOG Twitch II, presented by the highly authoritative Nutnfancy, offers an in-depth look at an 'old school' EDC knife. It covers the knife's utility, blade characteristics including AUS-8 steel with cryogenic treatment, assisted opening mechanism, and critically, the disparity in lockup between aluminum and plastic-handled versions. The assessment highlights its value for money and suitability as a user knife.
