Bah! I prefer the original stock over the ATI for several reasons:
-The ATI is thought to have not enough give to the poly frame, causing potential damage. Of course hp will cover our warranties no questions asked like always, but I never put my weapon in damage's way if I can help it
-It LOOKS COOL ALREADY! Four words from star wars: storm trooper blaster carbine. Need I say more?
-Pride. I honestly feel that the HP995 is one of the best pistol caliber carbines on the market if not the best. And, I gladly show other shooters that for a third the cost of their kel tec or baretta, they can get the same caliber with better service. Besides, if I wanted a gun that looked like a CX9, I would've bought a CX9!
