I'm going to be putting a 8-32x56 NightForce NXS MOAR on the AR50A1 I just ordered and was wondering if the one piece Armalite high 30mm mount 1.45" or the NightForce extra high steel rings 1.375" would be better? I did have the standard Armalite one peice mount 1.25" on my last AR50 (not A1) and it has hard to get a sight picture. Also is opticsplanet the best place to order the NightForce and rings?
