I'm confused. In one breath you toss around that some people can afford to sling ammo around like price doesn't matter and then you complain about the price of the stock.
At what point does being able to afford a product affect what a product is actually worth? For the record, I think slide fire stocks are over-priced too (but since the OP's post is about a trigger and not a stock, I will assume you didn't bother to click the link or watch the video). I never said anything about 'slinging ammo' either. Could I drop 5 bills on this? Sure. is it WORTH 5 bills? nope.
And price ALWAYS matters when talking about spending money. Only fools think otherwise and hence are soon parted from it.
