Lake City M855 SBR Ballistic Gel Test

This video provides an expert-level look at a custom 11.5-inch SBR configured for left-hand ejection, a significant advantage for suppressed shooting for left-handed individuals. The build features high-end components from brands like Superior Defense, Proof, and Aimpoint. The core of the video involves a practical, hands-on comparison of four different 5.56mm suppressors: Boss Silencers Guillotine, Resilient Stacy's Mom, Q Southpaw, and Ridgeback Defence Rhino X, demonstrated through live-fire testing. The presenter, with clear expertise, highlights the functional benefits and offers insights into suppressor performance.

This video provides an expert analysis of impending ammunition price increases, identifying the top three calibers likely to be affected first: 9mm, .223/5.56mm, and 12 Gauge. The speaker, demonstrating deep industry knowledge, explains the contributing factors such as raw material costs, supply chain issues, and the impact of military contracts on civilian availability. Viewers are advised to purchase these calibers before April 1st to mitigate expected price hikes.

Boondock Ballistician critically analyzes claims of 'record-breaking' 5.56mm ammunition, particularly from Shell Tech and Badlands Munitions. The expert instructor debunks inflated velocity and pressure figures, emphasizing the dangers of misinformation for reloaders and highlighting that standard brass-cased ammunition can achieve similar velocities within safe pressure limits.

This guide details the operation of a Daniel Defense MK18 SBR equipped with an EOTech optic, SureFire Scout Light, and suppressor. It covers safe handling, suppressor attachment, magazine loading, tactical reloads, and engaging targets at an outdoor range. The instruction emphasizes the suppressed firing characteristics of the 5.56mm SBR, as demonstrated by an expert from Daniel Defense.

This video provides an expert assessment of the Mk18's relevance in 2026, detailing its pros and cons. The speaker, demonstrating experienced knowledge, discusses critical factors like velocity, fragmentation range, dwell time, and effective range limitations. Recommendations are made for optimizing performance and considering alternative barrel lengths for specific needs.

This video compares the terminal ballistics of M193 and M855 5.56mm ammunition when impacting a cinder block. The M855 round, characterized by its steel penetrator tip, demonstrated significantly more destructive power, completely shattering the target, while the M193 caused a cleaner penetration. The comparison highlights the different performance characteristics of these common 5.56mm loads.

This video features a critique of a home defense AR-15 build by former Navy SEAL Jeff Gonzales. Key takeaways include the importance of a suppressor for indoor use, the critique of an overly complex sling, and recommendations for reliable optics. The discussion highlights the trade-offs of short-barreled rifles (SBRs) for home defense and emphasizes practical gear selection over complexity.

This guide details the tool-less field stripping process for the Beretta ARX-160, as demonstrated by a Beretta factory representative. It covers the quick-release barrel, stock, trigger group, and bolt assembly, emphasizing ease of maintenance. The representative highlights the rifle's modularity and ambidextrous features, noting its current military availability with future civilian plans.

This entry details the Fostech .50 Cal Drum Magazine, designed for Barrett M107 and 82A1 rifles, featuring a 20-round capacity and billet machined aluminum construction. It also touches upon the Fostech Rader .308 rifle. The information is presented with high technical focus from a manufacturer representative.

This video from ARFCOM News details a ballistic gel test of Remington's 158gr SJHP .357 Magnum ammunition fired from a 16-inch Rossi Model M92 carbine. The test highlights how carbine-length barrels significantly enhance .357 Magnum performance, achieving velocities comparable to some .300 Blackout loads and demonstrating substantial penetration and expansion in ballistic gel. The analysis touches on terminal ballistics theories and the unique behavior of high-velocity pistol rounds fired from rifles.
