I have a 30-30 with iron sights, it is a nice rifle for hogs in south Texas but I have a problem with the sights.

Last year someone dropped the rifle somewhere in the ranch and now I just can´t get it to shoot right. It places the shots in a pretty decent group but 20 INCHES TO THE RIGHT AT 100 YARDS!!!!

Since the sights don´t have any horizontal alignment I´m thinking of getting a new set with MOA adjustment.

Can you recommend any brand/model sights?

Any comments will be appreciated.

There is adjustment. The sight is either bent or it has moved in it's slot. Determine which and then correct it. You may have to drift it with a brass or other soft metal punch, but I wouldn't scrap the sights you have unless you just don't like them or they are broken somehow. Move the rear sight to the left a bit and shoot it, keep doing that until you're back in line.
