Im on the search for my first Ar-15 and I was at the LGS today (sportsman's warehouse) and they have the S&W M&P sport for $650. The next step up was a S&W M&P OP which is a flat top AR for $950. but then the guy showed me a Windham weaponry AR-15 that looked good and seem to be pretty much what I wanted for just over $800 bucks. but I have never heard of that brand before. anyone recommend them? or recommend something else? Thanks in advance!!!
