| I took my new M1A standard out yesterday and it was shooting very far left, so far that I maxed the windage adjustment of the front sight and needed to adjust the rear sight several clicks to finally get it on. I checked the flash hider for bullet strikes but saw nothing. Is it common for the windage to be so far off? I have several Garands and all of them have the sights centered front and back, I figured it should be the same with the M1A. |

Send it in to be repaired under warranty. Barrel may not be indexed correctly. This is what I was thinking as well, visually it doesn't look canted but something is off. I already emailed Springfield and have read their customer service is excellent but I wanted to make sure this wasn't normal. |

What's your definations of "very far left" and "several clicks?" Center the front sight. It is not used to adjust windage. Adjust windage with the rear sight. -- Chuck very far left being as far as it will go, several clicks being 4-8 (I don't remember exactly). Every instruction I have read regarding sighting in the M1/M1A says to use the front sight to set your zero and the rear sight is for adjusting for wind as needed. ETA: an Excerpt from Scott Duff: "To establish either zero, first set the windage so that the windage index line on the rear sight base aligns with the center line of the windage gauge on the receiver. This is mechanical zero. On a windless day, fire three to five shots at 100 yds. to establish a group. Some shooters fire from a bench rest to establish zero, while others use their standard slowfire prone position. Proper use of a shooting sling is essential with the latter method. If the shot group is not laterally centered, move the front sight in the opposite direction in which you want the group to move. The front sight is adjusted by loosening the front sight screw with a 3/16" socket-head wrench. Carefully move the front sight laterally along the dovetail base on the flash suppressor (or on the gas cylinder for M1s). Moving the front sight 0.008" will move the shot group one inch at 100 yds. Don't forget to tighten the front sight screw after you are finished! The windage zero of the rifle, on a windless day, should now be set." |

Adjust windage with the rear sight. -- Chuck Yes the front sight is meant to be adjusted for initial windage zero. You center the rear and adjust the front to zero just like a Garand. The only difference is the M14 has a notch in the dovetail so the front sight will not fall off if screw comes loose . It is unacceptable to have the front sight all the way to one side + adding more clicks at rear to zero. Rifle needs to go back to manufacture if a new rifle or to someone who can check the index and correct if able too. |

Op:
YES- YOU HAVE IT CORRECT. Zero the rear sight windage and then adjust the FRONT sight first. That way- you have the most windage adjustment in the rear when you get done. Preferably at wind zero. That said- I shot 2-3 M1A's competively back in the day and all had the front sight off quite a bit, if not on the edge. It didn't bother me and they shot great! If it bothers you send it back............... |
