I got my MarkIIFV in yesterday. I just ordered the EGW 20MOA base. Now I'm needing to order my rings. From the info I've gathered alot of you guys are going with the Burris XTR rings. My question is wheres the best place to get em, and which size. I haven't decided on a scope yet but whatever I decide on the bell won't be over a 50. I'll probably go with the Mueller APV that everybody likes so much. Thanks ahead of time for any info. Also if there is somewhere to order the rings from a hide sponsor that would be great.
