I had one, Vanguard Synthetic, 223 Rem. Yes, they guaranteed 1 moa.
- I liked the 24"-barrel, nice balance, and a little extra velocity.
- I liked the 9" twist for 50 and 55 grain varmint bullets.
- The 3-position safety was a nice feature.
- The action is sturdy, but a little stiff; extractor is excellent.
- The all-metal magazine I liked.
- The trigger was ok, it's two stage and adjustable. I got mine down to 2 1/2 pounds which is just right for my style of varmint hunting.
- The stock is sturdy and fit me well, but the barrel is not free floated by design. There's a pressure point at the tip of the forearm. This may be the reason I was never able to get it to shoot as tight as I wanted.
Mine shot under 1 moa with tailored reloads but not to my standards (1/2 to 5/8 moa) for a varmint rifle. Also, I had trouble with cases sticking in the chamber due to factory tool marks. My smith polished the chamber, and it was fine after that.
After using it a couple of years, I traded mine for a Tikka and never regretted the trade. However, I think this rifle has potential since it has a lot of nice features.
