The P90 has subsonic ammo.

This test compares subsonic and supersonic .22LR ammunition lethality using Clear Ballistics gelatin and a cloth barrier. Results indicate that heavy subsonic FMJ rounds can penetrate beyond the FBI's 12-inch minimum, challenging the assumption that they are less deadly than supersonic hollow points. The supersonic hollow point demonstrated expected mushrooming.

This video offers a head-to-head comparison of the highly unique HK MP7 and FN P90 firearms. While not a deep technical dive, it provides a general discussion and personal preferences regarding which firearm each presenter favors. The video highlights the "unicorn" and "flex" nature of these weapons and features full-auto shooting. The 1911 Syndicate, the content creator, also briefly outlines their background as a real estate company serving military/LE/shooting/hunting communities and their evolution into content production with a focus on having fun and doing things differently.

This video compares regular .22LR ammunition against subsonic .22LR when fired through a suppressed handgun. The subsonic rounds are significantly quieter, to the point of being barely audible over the host's voice, while regular rounds are described as comparable to a nail gun. The host questions if the substantial cost increase for subsonic ammo is justified by the noise reduction.

This review of the FN P90 highlights its unique bullpup design and the 5.7x28mm cartridge's minimal recoil, making it highly controllable. The progressive trigger offers distinct semi-auto and full-auto pulls, and its ergonomics, while unconventional, are designed for its role as a Personal Defense Weapon. The P90's history and intended use against body armor are also discussed.

This YouTube Shorts video title "Discover the P90's POWER: Will it break through or hold up? 💥🔫" suggests an evaluation of the FN P90 firearm. The inclusion of channel links for "Classic Firearms," "Outside The Warehouse," and a podcast related to firearms indicates a focus on firearm content, potentially including reviews, discussions, or historical aspects. The title hints at a performance test or durability assessment of the P90.

This YouTube video investigates the effectiveness and lethality of subsonic 5.56mm ammunition when fired from an AR-15 platform. The creator aims to debunk the common notion that AR-15s are not designed for subsonic loads by testing their performance. The video also includes mentions of their sponsor, Aura, and encourages viewer support through Patreon and PayPal, along with links to their Instagram and camera gear.

This short explains the meaning of the 'П' marking on Kalashnikov rifles, which signifies the 'Postoyannaya' or battle sight zero. The zero distance varies by caliber: 300 meters for 7.62x39mm (like the AK-103) and 400 meters for 5.45x39mm variants (AK-74, AK-105, AK-12). The AKS-74U 'Krink' has a 200-meter battle sight zero.

The Ruger Mark IV Tactical .22LR is presented as an excellent suppressor host, featuring a traditional grip and a 4.4-inch bull barrel that keeps rounds subsonic for quiet operation. Its single-button takedown mechanism allows for rapid cleaning in under 54 seconds, a significant improvement over older models. The pistol offers good accuracy at 15 yards and is compared favorably to competitors in its $400-$500 price range for build quality and reliability.

This video tests the practical accuracy of a Kar98k sniper rifle with a ZF39 scope out to 1,100 yards. Despite its age and limitations, the rifle proved capable of hitting targets at extreme ranges with proper technique. The discussion highlights historical German sniper programs and the use of reticle holdovers for ranging and aiming.

This review details a practical accuracy test of the M21 SWS, a sniper variant of the M14 rifle, chambered in .308 Winchester. The test engaged targets from 150 to 800 yards under challenging environmental conditions. Despite a mechanical jam and shooter error, the rifle achieved a 32 out of 40 hit ratio, demonstrating its capability at extended ranges.
