Optics, magnifiers, and back-up irons are all popular choices, along with LPVOs.
The SIG optic along with some Armscor ammo was giving the owner some frustration on zeroing and accuracy. Remember 55 grain in a 1-7 twist is going to have you questioning is it me, the ammo, or the gun. Try another brand of ammo or a heavier bullet weight after verifying the optic is secure.
If you want to mount your MAGPUL sights backwards it robs you of rail space when stored.
Running a dot and magnifier without a backup iron? That’s up to you, it’s cheap insurance if the dot dies. Have spare batteries and change them annually or semi-annually.
The EOTech Optic directions were not for bullet impact, but dot movement. We always remember that after the bullets move in the wrong direction.
This S&W Performance Center rifle had the buffer tube come loose after a few rounds. Remember never use Loctite or any other adhesive, torque and stake the castle nut if the end plate is steel, don’t stake an aluminum end plate.
Always mount your optics on the upper receiver, not bridging the upper receiver and forend, and definitely not on the forend.
Check your optics and accessories and index mark everything after you verify the position.
