OK, I reffered to my printed catalog as well. You're right, it is reffered to as a national match rifle there. Well, unless mistaken, that "national match" gun in the catalog is a standard flat top rifle. It too will have a standard trigger and barrel.
Both rifles will have the same 20" Chrome lined HBAR with the milspec 5.56 chamber (not a tight match chamber). They will both have standard milspec triggers which are somewhat heavy. The only real difference in the v-match and that gun is the Vmatches free floating handguard (which will improvew accuracy) and the shaved front sight.
What purpose would you like this rifle to fill?
If you are looking for more of a match gun, maybe look into their DCM model. This model will come with a free floating handguard, match sights, match trigger, match grade barrel and chamber, etc, etc.
