Thank you for your thoughts! I definitely don't have any agenda, but figured that other people here were probably wondering the technical merits of the Red spring vs. the Armalite one like I was. I don't buy small anecdotal samples of "This is the best thing ever!" and figured if anybody had taken a solid look at them it would've been you since you state that you carry products based upon performance. "Flavor of the month" was referring to the back and forth people constantly do about what's the best way to optimize their buffer system. One day it's "use x buffer" and the next it's "use y spring instead!" Soon enough they come full circle and recommend "x buffer" again... I find it fishy when Springco's page recommends their Red spring for Armalite pattern receiver extensions, but their customer service then tells a customer "Oh yeah, that Orange spring that you ordered for your Armalite pattern receiver extension, because somebody erroneously recommended it online, will work great too!"
