For me a lowball offer is $200-$300 less than what i am asking . I always try to ask for close to market price less 10%. in this case i have over $500 in extras for this gun so I am sticking with market price. If i was in the market for another M1A i would consider this gun . By putting in "NO LOWBALLERS" I like to think it weeds out people who are not serious buyers so we don't waste each others time.I don't mind taking some loss in a sale, if you pay full market price in the beginning you can't really expect not too.
