To get the rifle, craft it at a chemistry station, or open the console and search help M1903 4 weap, and use the player.additem ## to get the rifle or mod an existing hunting rifle.
You will need a fair amount of resources, and four level 1 perks: rifleman, blacksmith, armorer and gun nut. The can opener is level two of the same perks,
and twice the resources. So start scrounging, or scrapping.

There is also a semi-automatic version that you can make, if you get tired of a bolt action rifle. Alternatively, tou can make a Pedersen Device like apparatus,
and fling .30 Lounge ammo at your enemies. The ammo is added to the leveled lists, though it is somewhat rare, so use it sparingly. New in this version is a proprietary .30-60 ammo and the ability to change the ammo loadout at a workbench.

Now all CC factions are included so you can change the look of the weapon to suit your character's loyalty.

I have removed the old, longer barrel and stocks. You will now only have the original sized stocks, and the barrels are now shared between the A1 and A3 variants of the rifle. This mod now also has a unnique firing sound, completely separate from the hunting rifle. The Pedersen Device as well as the Can Opener have their own sounds as well.

I have added back taped stocks, and the ability to change the color of the tape. Thanks AsXax and ShoeBurglar!

I have moved the camera on the iron sights back, for more authentic feel, makes it a bit harder to aim.
Also new in this version is a see-through scope that has a reticle that is changeable. You get the choice between a fine cross, a duplex cross, a german style reticle, and a T-post reticle. All drawn be myself and positioned perfectly for maximum presicion.  After all, the M1903 is famous as a very accurate rifle.

You will need a right handed mod for the hunting rifle, there are currently five good mods:
