JMAC shows his personal armory such as the AK-105 and shows the new CRSU... "In this new series, I’m opening up my personal collection to give you a deep dive into the builds I actually run and the engineering behind them. Today, we’re breaking down my personal AK-105—a build that has survived years of demos, events, and testing despite a warped receiver.

We’re also talking about a common mistake many enthusiasts make: neglecting the proper cheek weld. I’ll show you how we solved this with the CRSU (Adjustable Cheek Riser), which offers up to .8 inches of rise to ensure your eyes are perfectly aligned with your optic every single time."
