How do you adjust barrel line up on a baikal spr94 combo rifle shotgun?

To adjust the barrel lineup on a Baikal SPR94 combo rifle-shotgun, first ensure the firearm is unloaded and safe. Then, visually inspect the alignment by looking down the barrels and making adjustments to the forend, if necessary, by loosening the screws that secure it. You may also need to adjust the rib or use a shim if available to fine-tune the alignment. Always test the alignment after adjustments to ensure proper aim and functionality.
