Looks like a Springfield Sporter, and a very nice one at that. Springfield Sporters were never in "military configuration" (i.e. full stock, upper handguard, bayonet lug, rear sight on the barrel, straight grip or scant grip, etc), they were sporters. Note the barrel band fits the barrel and stock as is, and has a crosspin to secure it. Very nice rifle. Springfield Sporters can be worth a bit of change. If you intend to sell it, have it appraised by someone who knows about Springfield rifles.
Looks like someone put the front sight blade in backwards.
As far as shooting it in matches, it is not in military configuration so it will not work for military match. I am sure there are still sporter matches in various locations around the country.
