Sometimes this board is so full of dickheads I lose count who's being ornery and who's just a dickhead.
I digress.
For non-critical parts, like stocks, scope mounts or even red dots, WHO FUCKING CARES IF THE THING WAS MADE FOR AIRSOFT!?!?!?!? If it works, it works. If it doesn't, well the guy's out his $30 for a collapsible stock. Does that have to spoil your day when someone uses an airsoft part on a firearm? Does it hurt your feelings, make your vagina burn? Does it have to warrant a shitty post you've made 1,000 times already?
There are hundreds of us, thousands of us, who use our AR's for nothing but fun guns and don't rely on them, abuse them or put them to their deaths in training drills. For us, an adequate part that works, saves us hundreds of dollars and makes us happy is a thing of joy.
I have a Knight's knockoff cantilever mount, that cost all of $20.00 holding up a $95 Tacpoint on my Bushy. Know what? They work good. Seriously. Very rigid, no problems or failures of any kind....and I've dropped the rifle a few times. Take the thing off, put it back on...holds zero! How is that possible!? Experts? Do I defy the gods?
I saved hundreds of dollars using airsoft parts, and for a plinker it's just the peaches. Am I wrong for doing this to a range gun? Do I not deserve to stand amongst you Delta-Seal-Team keyboard operators with a $200 mount holding up a $500 scope on a rifle that's primary function is to look pretty for show and tell pictures?
Ugh, every time these threads come up, the board seems to swell with arrogant pricks who seem to believe that the only way is theirs, the only use of a rifle is SHTF, and anyone who marches out of lock-step with the horde is a fool.
