Had to look up the Express Model. Kind of interesting. Might would have considered it. The express has a 16.5 inch barrel vs the standard 20 on my new acquisition. That shorter barrel is also threaded and it appears the furniture is more durable.
Like the classic styling of mine and 20 inch barrel makes for a nice compact package. Suppressor support not needed.
Family is in town this weekend, plus my range is hosting a 4H event, so no chance to sight in and shoot some.
Had to show it off to a few hunting/gun enthusiasts after work today. First comment was this should be a great varmint option when shooting 5.56. They were all impressed with the Sig Whiskey3 scope.
