OK, so I have an M&P 15 psx, love it. I decided to spring for a better scope and decided on the Burris 3x tactical red dot. It looks cool and I am / was pretty happy with it.
When I got it home, unbox, mount on gun and the reticle is slightly rotated to the left. Did some googling and found that this is not uncommon issue with these scopes. Nuts. So I decided this scope would go back and I would put my older NCStar scope on it. Up till now, I had not put the NCStar on it. The first time I looked through the NCStar - the reticle was rotated to the left! Crap. Really? So, at this point I do NOT think it is the scope, but maybe the rail itself. Has anyone seen something like this? Is there a way to fix / check this? I'm assuming LEVEL is the should - would this be a warranty issue if it is not? Not sure what to do at this point, if the gun is off. |

Put the rifle in some kind of rest. Get a bubble level (to check the rifle and optic), and a hang a weighted line (to check the reticle). I know Ive remounted scopes countless times because my eye couldnt decide what was level or not.
Dont use a fenceline or building as a reference, they may not be square either (thats what the weighted hanging line is for) |

Great input, here's what I did.
hung a string across the kitchen/dining room and gun on counter top across the room. Used a level to be sure the top rail was level. Observations: the rear top rail was consistent end to end. the front top rail was "loose" and did rotate a few degrees. So, on the front bipod, the gun could rotate in the direction of the reticle drift. BOTH scopes showed to be off (highly unlikely), in the same direction when mounted to the rear top rail. Holding the scopes, both reticles appear vertical, but that is not exact science. Net - sitting on the bipod, it is conceivable that I'm rotating the gun slightly. So, assuming now that both scopes are "good", I need to get the front of the gun (front rail system) square and tight. I'll google some more. Thank you so much for the tips. Being an engineer, one might have thought I would have thought about that! Sometimes I trip over those darn trees on the way to the forest! |
