I have an M1 with an arch angel stock. Would it be ok to install a Trijicon scope? I already have scope mount mounted. Expert Answer

Yes, it will just need to be mounted over the top of the receiver.

Helpful Positive Review great optic! by Michael Yoder, Verified Owner, November 14, 2023
I put it on a springfield armory m1a and it performs very well! I killed a deer with it at 140 yards no problem and could easily kill one twice as far. The reticle is too bright in direct sunlight but you can cover it and make it dimmer.

Helpful Positive Review Simple Strong and Built to last by Krayon, Verified Owner, March 21, 2021
I wasn’t so sure when I purchased the crosshair reticle. I’m use to the chevron but the crosshair reticle is perfect for my scar 17. The tritium is bright and the fiber lights up the center just right. I would buy one again in a heart beat.

Helpful Positive Review ACOG 3.5x35 .308 Ballistic Red Chevron by Legacy Reviewer, November 20, 2010
Put on my new FN SCAR 17S 308 cal. Was almost dead zero at 100 yards after mounting right out of the box. After 8 rounds of sighting it in, put the next 20 rounds all in a 1 inch group at 100 yards. Crystal clear optic and light weight. Would recomme...
