I agree. Mk 4 scopes currently do not have a big draw in the civilian sector. RickI think it's just due to soft sales of the MK 4 line. The MK 4 has been around since the 1990's when they were the top scope. The "Tactical" crowd has moved on from the MK4 so it's no longer that popular any more. Leupold probably see no sense in trying to support a diminishing civilian market.
The product still would be in the catalogs and on price lists, there would need to be some level of dealer and customer support and they would need to maintain some level of product inventory. Specific commercial packaging would still need to be maintained. It simplifies operations (and thus reduces overhead) when a product is simply dropped from the commercial line up. When it comes to running a profitable business, it is prudent to reduce product offerings if there is not adequate sales potential in that segment of the market. RickI dunno - if they have a production line up and running for military contracts anyway, why wouldn't they continue to offer them to the civilian market? No need to advertise or market them, it would be word-of-mouth for those 'in the know'. Can't get much better marketing than that.
