I've used Burris 2X, Leupold 2X, and a Tru-Glo Red Dot on my Super 14 .44, all with good results. But I believe the Leupold is the best. The crosshairs are better defined and work better in brush. The dot is neat but gets dim to see through in low light where the scopes will gather light right up until sundown.
On others I use a Redfield 2X7 on a Super 14 .22 LR Match, a 3X9 Burris on a Super 14 .223, and a Leupold 2.5X8 on a 12 in. Custom Shop .30-30.
All have given excellent service.
