Questions & Answers
Is it compatible with the Acog and the m4a1 railing system? Expert Answer

The Strike Industries T1 Riser Mount is not compatible with the Trijicon ACOG. It will only fit optics that share the Aimpoint Micro footprint. Email us at Techsales@opticsplanet.com and let us know what model ACOG you have so we can recommend a mount that will work for your setup.

Not lower 1/3 exactly by Jim C, Verified Owner, June 16, 2020

Best bang for the buck so cheesy to say by Ben, Verified Owner, December 30, 2025
This mount is by far the most affordable mount for a micro footprint. I have three now. They are superior to most factory mounts and have a big enough screw to stay mounted on the rifle. Holds zero which is all I can ask for.

I bought so I could have a lower 1/3 on an sig red dot. Affordable Lower 1/3 is harder to find now since the high mounts for NVGs became popular.
