Just changed the battery on my Shield SMSc mounted on Hellcat. Battery was 18 months old. was a little dim but perfectly shootable. Am in process of installing a Apex trigger assembly. Apex shipped same day and I had it in 3 days, great service.
I am sold on optics for pistols. Great for old geezers with poorer sight. My Shield also has optic, Vortex Venom. Its battery only last 4to 6 months, but easy to change.
To answer:
You can but its an awkward mount. Can also reverse a cantilever by reversing it and screws, but may be a non natural fit.
Also, i run a very nice 1x6 Vortex and it seems a little to “less” magnification than I would want on an M1A.
I prefer the higher power on the reach out and touch M1A
