AR guys spend a lot of time and money on their rigs. Accessories, special parts, all that... to overcome perceived deficiencies in the design. To them, this is so important.
Take a pedestrian firearms manufacturer like Ruger, who makes guns for the common man, have them mass produce a rifle at a fraction of the price point of the AR guys' expensive firearms, which works better, has a better warranty, and naturally these guys are going to poo-poo the rifle. After all, it doesn't wear the "Rolls Royce" or "Rolex" badge of their fine firearms, it wasn't carefully crafted out of hand selected parts and accessories. Ruger owners didn't pay the dues to the country club like the rest of these guys did, so Ruger owners can't play golf there!
"Nyah! Nyah!" (as Thurston Howell III would say).
Sorta like a Harvard graduate losing a debate to a community college graduate... ya start to wonder where all that money spent on education went, yes?
If it says Noveske it has to be better than Ruger, yes?
Ego is such a fragile thing. Especially when it results from large expenditures of money.
