Customer Questions & Answers

Will this work on 45 colt long rifle?

• If your rifle has a flattop upper receiver with an M1913 picatinny rail. If not, then you'll have to mount the optic over the hand guard with some different hardware.

Would this handle recoil from a 12g ok?

• It probably would but it is really not designed for use with a shotgun.

I live in a dark area w/ few lights. With the Night Reflex part of the sight; how well do you see in complete darkness, full moon & suburbs w/ lights?

• The dot will show in almost total darkness but unfortunately your target will not. But the m21 is awesome when paired with a night vision scope like a PVS-14. The dot is bright but not too bright and needs no special setting for night vision like some other red dots.

How long does the tritium last and is it replaceable? If so, how much does that cost?

• Mepro claims 12 years but in my experience you can expect 9 to 10 years of life from the tritium vial. Yes, you can send it in to Mepro for replacement. I can't tell you how much it costs or what turnaround time is though.
  If you buy this optic get the 4.3 MOA dot. Don't get any of the other reticles. They are too big.
