The Most Insane 5.56 Ever Created

This video from Guns Blazing Ranch features a direct comparison between an AK-47 (7.62x39mm) and an M16A1 (5.56x45mm) in a concrete penetration test. The AK-47's heavier 7.62x39mm round demonstrated more explosive fragmentation, while the M16A1's 5.56x45mm round caused the concrete block to split into larger pieces. The demonstration highlights the distinct terminal ballistics of each caliber.

Sootch00 provides an enthusiastic review of the next-generation FN SCAR rifles, highlighting a dramatically improved shooter experience. Both the SCAR 17S and SCAR 16S are praised for their exceptionally smooth and soft shooting characteristics, with the reviewer noting remarkable accuracy even when shooting standing. The modularity of the new generation is also a key point, allowing existing owners to upgrade their current SCARs.

This review of the HK MR556-A4 after 6,000 rounds, conducted by Regular Guy Training LLC, highlights exceptional reliability with zero malfunctions across diverse ammunition and magazine types. The piston-driven system requires minimal cleaning, making it practical for serious use. While heavy and expensive, the rifle delivers on its promise of high-end performance and reliability, as assessed by an experienced instructor who used it in training classes.

This video provides a direct comparison between the PSA AK-P (5.56) and the Zastava M85 (7.62), highlighting their physical similarities and key differences. The host, demonstrating experienced shooter insights, expresses a strong preference for the Zastava M85 due to its exceptionally flat shooting characteristics, particularly when suppressed, despite potential aftermarket furniture limitations. Viewers are encouraged to consider their caliber preference when choosing between these AK variants.

This video provides an expert-level comparison of 5.56x45mm NATO and 7.62x51mm NATO calibers, drawing on combat experience and ballistic data. It highlights 5.56's advantages in logistics, recoil management, and close-quarters combat, while 7.62 excels in barrier penetration and long-range effectiveness. The 'best' caliber is mission-dependent.

This video showcases a custom AR-15 build with striking red anodized accents on components like the buffer tube, safety selector, and charging handle. The build features a micro red dot sight and a Magpul PMAG magazine. The presenter humorously compares the expense of custom firearms to past habits, highlighting the financial commitment involved in such builds.

This comparison tests the .50 AE Desert Eagle against the .44 Magnum in various barrier tests, including wood, steel, sand, and concrete. While both calibers showed impressive power, the .50 AE demonstrated superior performance in ballistic gel with deeper penetration and a larger wound channel. Ultimately, the video questions if the .50 AE's marginal gains justify its significantly higher cost per round compared to the versatile .44 Magnum.

This video provides a detailed comparison between .223 Remington and 5.56 NATO ammunition, demonstrating their performance differences through rigorous barrier testing. While visually identical, 5.56 NATO shows a slight advantage in velocity and energy. Crucially, 5.56 NATO exhibits superior barrier penetration against lumber and steel, whereas .223 Remington struggles. Specialized rounds like M855A1 also show enhanced performance against sand barriers.

This video tests the lethality of various 'less lethal' shotgun rounds, including rubber buckshot, bean bags, and specialized projectiles. The .410 rubber buckshot demonstrated significantly higher velocity and penetration than 12-gauge versions. Bean bag rounds proved to be the most damaging, causing substantial plywood destruction and ballistic gel displacement, leading the host to conclude they are the most lethal 'less lethal' option.

This video compares 9mm, .40 S&W, and .45 ACP through various barrier tests including lumber, sand, and concrete, alongside ballistics gel testing. While all calibers performed similarly through most barriers, the .40 S&W showed slightly better penetration and expansion in ballistics gel. The host ultimately favors 9mm due to its lower recoil and higher capacity, despite the .40 S&W's respectable performance.
