We were there this summer. I purchased the Service Grade rifle off the rack. I took 2 hours to go through every rifle on the racks. I'm happy with mine and my buddy is happy with his. They both shoot well. Not match grade, but certainly well enough for two old duffers to shoot in military matches.
I would spend my extra $150 on ammo. This summer they had Greek 30-06 in enboc clips for $200 per case of 768 rounds. We bought 3 cases and should have bought 10. It is accurate and clean burning.
Just my 2 cents.
