Seriously, people putting airsoft stuff on real guns?
Anyway, I'd need to bring in a guy who is an equal match for my guy's experience to actually settle things. Like one of those "Youtube guys", preferable one around his age. I think anyone vs the Beard or Haley would shut them up.
You know the type.
They go to gun shows and buy all the UTG accessories they can find. They have $1k in accessories on their rifle, and every single accessory is the cheapest bare bones thing they could possibly find.
Hey, my UTG red dot works pretty good...
...on my M&P-15/22. But I'd never put it on my 6920.
Forums won't let me editing my posts...
Anyway, if you can't match his shooting abilities, I'd say he has a thing or 2 he could teach you.
