Just got a Polish M-44. With the bayonet closed it hit 5 1/2 inches left and dead on if high with it extended. Noticed the front sight was peened in place. So, if I remove the bayo I still have  to guess and re-peen right? Also, where do I get scope mounts for this and my Finnish M-39 which shoots 1 inch groups with open sights. I figure that a scope might tighten them a little. Thanks.

What's wrong with shooting it with the bayo extended?

Scope mounts are available from Tapco and FAC.  Adjustable rear sights are available from www.mojosights.com

I recently got my Russian M44 and it does the same thing, they are sighted in that way at the factory.
My only beef with the setup is having the bayo extended defeats the purpose of it being a carbine in the first place. It is a very handy rifle with it folded.
Sorry no answer for you, I am having the same thought and looking for an answer.

oh wow, I didn't believe it when I read it on www.mosin-nagant.net

The carbine can be fired with the bayonet folded in place or extended, but it is important to note that the M44 was designed to be fired with the bayonet in the extended position. This design fact means when the bayonet is not extended, the point of aim/impact changes.

And my hammer n' sickle one doesn't do anything different either way, I had to try that out first thing when I got the rifle a couple days ago, cause I thought that sounded weird. That and it's my first gun with a BAYONET! yee-uhh.
