Didn’t take photos yet, but finally got my Geissele order of an Aimpoint Comp M5 and lower 1/3 cowitness Geissele mount delivered the other day.
Installed the sight to the mount with Loctite torqued to 12in-lbs per screw torqued in cross sequence. Mount is machined from a billet of 7075-T6 aluminum, and so is the Comp M5 so no helicoils needed. I love Aimpoint’s micro mount interface with an integral recoil slot machined into the bottom of the sight, with the Geissele mount having a corresponding lug that is a snug fit. The mount also has two lugs on the bottom that fit into the 1913 Picatinny rail on the upper receiver, with a 1/2” nut cross bolt securing it all torqued to 65in-lbs which should be around 1250-1300lbs/sq-in of clamping force.
I mounted it to my Knights Armanent Co. SR-15 E3 Mod 2 16” 5.56 NATO carbine. Hit the range that evening to put a 50/200 yard zero on it. Zeroing went smoothly with IMI M855 62gr steel core ammo, M855 isn’t exactly known for accuracy but the IMI is more consistent than Winchester in my guns and this held the black of a B8 bullseye target at 200 yards with a non magnifying optic so I can’t bitch. With a 2 MOA dot covering 4” out there bullets we’re landing under or on the edges of the dot. The Aimpoint Comp M5 and T2 both have excellent glass and for my eyes both provide a crisp dot, with edge for my astigmatism going to the Comp M5. Adjusting the windage and elevation was no problem and the clicks seemed to track according to specs. The Comp M5 runs on ubiquitous AAA batteries so you can get them anywhere.
This particular carbine doesn’t seem to give a shit what ammo it is fed in the 62gr-77gr weight class with a 50/200 zero it will shoot pretty well POA=POI without any pressing need to make sight adjustments. So I zeroed with the IMI because I have a lot of it on hand. A brief couple of groups with Hornady Black 62gr and IMI 77gr Sierra Match Kings gave much much better groups, that were near enough the same POA=POI that I’m satisfied. It’s red dot sight equipped carbine, it’s simple put dot on target press trigger from point blank to 200 yards.
Currently set up this way so my wife can pick it up and repel boarders if needed, as it’s currently the lightest handiest AR I have. It was wearing a magnified optic but will be set up this way until I tax stamp another lower as an SBR and build a proper 12.5” house gun with a quiet maker on it.
Weapon light is a Cloud Defensive OWL, which I am very pleased with so far, but I will concede that on a longer rail it’s tough for a shorter statures shooter to reach the integrated pressure pad if the light is pushed up all the way forward.
