Okay, the local store just lowered the price of the 15-22 MOE today, so I went and picked one up. Also, just ordered the BSA Tactical 4-14x44 Mil-Mil scope from Midway, along with Butler Creek hinged covers. Looks like the scope will clear the sights, and I'll probably go with the Burris AR-PEPR Scope Mount, just because it looks good and has dual clamps.

Thanks to everyone for their suggestions and help. This is going to be fun!
