Picked up a new SPS Tactical .223 last weekend. Found a Cabela's tactical 6-18 scope and was shooting the next day. Did a visual bore sight and got it shooting real well at 100, 200 and hit 9" plates at 300 and 400 yards. What a blast to shoot, I could darn near see the bullet hit the target. Shot nearly 40 rounds and got one 1/2" group at 100 yards. The verdict is still out on the scope but for a total of $679, I think it was well worth it.
