In the past I made a couple of offhand rifles with no rod or rib,shotgun style half stocks and my own locks and triggers.I used a Lyman 17A front sight and the wide post insert and a folding tang peep sight.Walnut for stocks and barrels from Bill Large who is deceased but a Green Mountain barrel will work.These rifles were influenced by the high end long range types but need not be as elaborate and are not hard to build.To answer the original question there will be seen a variety of rifles ranging from production types like T/C and CVA and the long rifles
with better sights and the Hawken.I don't know if primer ignition is allowed is not.Hopefully,some of the competitors will chime in here.
