Giving you guys a cool quick update on my Faux Mk18 Build. I recently replaced my Mega Arms lower for the Rainier Arms A-DAC (ambidextrous dual action catch) lower receiver. Its a Great practical and functional lower that has the ability to lock the bolt to the rear by using the magazine release. I explain it in greater detail in the video. Check below for the build list and link to the part on Rainier Arms Website. Thanks for watching!
