Realities of Long Range with 5.56mm [Mk262 to HICAR] feat. Sidewinder Concepts
One video, plenty of range. The single new upload on 9-Hole Reviews, "Realities of Long Range with 5.56mm [Mk262 to HICAR] feat. Sidewinder Concepts," drew more than 54,000 views on its first day and has kept going since. Nothing on the channel is moving faster right now.
The subject suits a channel whose about page states its standard plainly: no flattering three-to-five-round groups, just hits on steel at 500 yards and beyond. Here the question is how far the AR-15's small cartridge can honestly be pushed, from the Mk262 load, the 77-grain round long used by U.S. special operations, to a Geissele HICAR rifle. The guest is Adrian of Sidewinder Concepts, and several viewers say they have taken his scoped carbine class, where the line between what is realistic and what is just fun stays with them.
The comments read like a range day. The most liked one comes from a viewer who served in the war on terror and says the video's figure for a 14.5-inch barrel matches what he saw. A hunter says his own limit sits well short of that. Someone else wants a ballistic dummy put out at 1,000 yards, and another jokes that his .357 lever gun is a thousand-yard rifle if you add up ten shots.
The older material is still working too. The Geissele Super Duty test to 800 yards is the next busiest video, and across the channel the daily views are running ahead of their usual pace. Among similar channels, Daniel Davis / Deep Dive and Combat Veteran News are having the big weeks, while Perun's is busy and steady.

@ModernTacticalShootingSee it on YouTubeMy 357 Henry lever action is a thousand yard gun..if you add up 10 shots
@turtlehermit8326See it on YouTubeI took Adrian’s scoped carbine class and it was so worth it. Understanding “reality vs fun” is very apparent when you leave. Highly recommend
