Large distributors can "build" the rifle they want i.e. mine came from Gander Mountain no threaded barrel with 25 rd mag I didn't really care since it is basically eye candy on a 22. Maybe it is a "compliant" model that makes their inventory control easier but it was in GA which is still a free state. I also have a DPMS LR-308 that is not a standard catalog item, when I contacted DPMS they responded and advised it was a special "Distributor" build for GM only. It has the flash hider/standard mags etc. Walmart is certainly big enough to order a specific model with certain features added or deleted as they see fit. Might cut the cost by $3 and make them a bunch of money :-)
