Really like the look of this lower and want to buy one. I first found it from Core 15 but the "HARD CORE 15 on the right side and "GTO" with wings on the left looks so cheesy to me. I saw the same exact receiver on a GPI custom rifle so I'm guessing a third party makes these to put other roll marks on them. I'd like a plain one to have my own engraving on it! HELP PLEASE!
