I ordered a bunch of stuff from Sportsman's guide this evening including:
WX2-51733 1000 Portugese NATA 308 @ $132.97
WX2--65523 1000 Lake City XM193 @ 170.97
Those are Buyer's Club prices.
Both are in stock, but get this, while the 308 gets a $20 bulky shipping charge for the wooden box, the XM193 didn't incurr an additional shipping charge. Shipping for the XM193 along with a half-dozen other items I ordered (hiking boots and camping stuff) was only $17.
Use SPG458 for $10 off of orders over $150. It looks like you should be able to order the XM193 for less than $180/k with shipping.
