Helpful Positive Review Good for the money by J Money, April 23, 2019
This seems to be a decent, inexpensive micro dot. I installed it on a Mossberg 590 12 gauge. I only fired about 20 rounds to zero the optics but it’s held up so far. I’ve checked the optic every day to see if the Shake Awake function has conserved th...
