Up for sale is a very lightly used 4.5" sig MPX barrel (latest generation). I purchased the MPX just last week and have only shot about 200 rounds through it. Full disclosure; the barrel shoots excellent without a suppressor. The group pictured was 5 shots of federal 147gr at 25 yards. With the 3 lug adapter and omega-9k, I'm having accuracy issues. Maybe someone else will have better luck with it. Selling this off to help fund an ILWT barrel with adjustable gas piston. Will include the ILWT 3 lug adapter for my asking price. Price is shipped, Venmo or Zelle for electronic payment, or USPS money order.
