Another internet myth is that a Mosin " has the barrel "" tuned "" for the bayonet " and shoots better with it on the rifle . Facts : any movable , vibrating weight on the barrel is bad for accuracy . Mosin's were designed to be made quickly and in large numbers , the barrel has a convex mating surface and is screwed in until the rear sight base is close to the top . The resulting barrel pressure with vary from 25 to 250 lbs [ on the ones I have removed barrels from ] , not hardly " tuned " . Russianicon snipers did not shoot with bayo's on , a lot of their snipers had non scoped rifles .
It was doctrine that the majority of rifles (i.e. Dragoons, Infantry Rifles, M91/30s, etc.) were sighted in with the bayonets mounted. If you don't believe having a bayonet mounted makes a difference, you likely haven't shot a rifle with or without a bayonet, as it most definitely changes POI (and there has been many attempts to mitigate those effects throughout history, if it didn't have a effect militaries would have ignored it as opposed to doing things like the M95 Stutzen bayonets with a sight mounted on the bayonet, or changing mounting techniques like the Germans removing the muzzle ring). Inexperience has nothing to do with it, the barrel harmonics, and how the bayonet is mounted does.

I can't even believe I have to try and explain this concept.
