I've bought the scoped combo before. The scope is MOA adjustments on a MIL Dot reticle. The rings and scope are 1" are suitable and usable. Gets you shooting right out of the gate and let's you upgrade where you feel it is the most useful. On my 6mm ARC I changed the stock to a Stockys and upgraded the scope after 1 season. Neither was "required" but more of a want. If you look on gunbroker you can find the combo with the Houge stock and Nikko Sterling scope for between $490 and $510 with no CC fees or shipping from time to time. Good way to get into a ready to shoot gun with money left to buy ammo.
