I am looking to purchase this item, I need a 7" for a 8" 300 BLK barrel on a Noveske. I can pay via paypal, I have had the torx head screw that tightens the hardware to the barrel nut strip before, (probably from me not using a proper torq wrench) but stripped anyhow. So I have to ask , is the hardware stripped or damaged in any way? are there any blemishes on the rail, not a deal breaker if there is cosmetic damage. I am willing to pay 175 as asked. Are there any other fees? i,e. shipping, taxes, etc... I am in Austin TX if I can buy in person.
