Nice gun, and vid! These things are so much fun! I recently grabbed a couple airsoft replicas myself for casual plinking. Might even try my hand at playing in some local matches. I have a sig p229 that uses green gas instead of co2 and an electric M4. Much quieter than my air guns so I can even fire them at targets in my house without triggering the neighbors, though the motor on the electric m4 is louder than the sound of the bbs leaving the barrel 🤣. Next one I get is going to use an air tank and regulator which should sound more like your DPMS. Might as well put my refill station to some other use than just my pcp lead shooters.
