To start off, I bout a mosin nagant m44 carbine 9 years ago for $50 and it has been a project ever since.
It was in bad shape when I got it. Most of the finish was gone, rust all over the outside and a cracked stock.
I quickly polished the metal and lopped the handgaurd portion of the stock of and removed the bayonet.
I then discovered that the removal of all that wieght made the gun punishing to shoot and the new sights I soldered on failed to stay put.
I eventually turned down the bolt handle, using a bolt meant for a mauser.
Added a Boyds stock and a timney trigger and a king armory muzzle break. But the front sight was still problematic and I really wanted to use an m14 front sight sooooooooo.
