*****SOLD*****I have an excellent condition stainless steel barrel for a Glock 17 threaded 1/2-28tpi. Grooves are nice and sharp in the barrel. Round count per original owner is 200-220. Looks like fewer than that to me. I got this in a trade and don't have a use for it. No manufacturer markings. It has an oval cut out of the threads on the underside which I'm assuming is the identifier. Maybe AWC or Gemtech? They are intentional and do not interfere with device application as it has been tested. I can send pics upon request. Price delivered USPS Priority $130obo PayPal or USPS MO. eBay ID is the same!
