All respect to the SMLE, why not get a 1903 Springfield? It used a bayonet comparable to the Smelly’s (and the Mauser’s), plus, you’ll have ammo compatibility… I mean, unless you sock away a few thousand rounds of 303, you’ll need ammo eventually. The Springfield uses 06 ammo.
Plus, it has a whip-ass bayonet.
