Below is review I wrote on the Sportsman's Guide website for this optic. The one I have now I ran on my AR but I'm seriously considering another one for my soon to be out of jail Patrol 308. This is my initial review. I finally got it out the desert to zero and see how it shot at range. Initial zero was quick taking less than 10 rounds. Out of the box zeroing at 100 yards I only required 6 clicks of elevation and 6 clicks of windage adjustment was was centered on the target. I added a cheap "coaster" for a throw lever and found the magnification adjustment to be smooth and easy but not so easy that it will flop back and forth and change on you. The turret cap set screws MUST have locktite installed or you will lose them. The screws come without locktite on them (really the only reason I gave it 4 stars instead of 5) and will back out. I fired 300 rounds under the optic that day and almost lost the windage turret. The turret cap set screws are also what clamp onto the adjustment wheels and if they come loose turning the turrets will do nothing but spin them without actually adjusting anything. As for not coming with a mount. Who cares I didn't expect it to come with one. I mounted this using a 35 dollar UTG Throwlever offset mount. You pretty much have to go with an offset mount if you want to mount this to an AR type rifle/carbine. Again as with the optic itself, with the UTG mounts blue locktite is your friend. After zeroing I was able to easily make 2 and 300 yard hits on 66% sized IPSC steel targets. Being this is an initial low round count review I can't say it would make a good Home defense optic or not as it's reliability hasn't been proven to me but for the cost and what it's done for me so far I'd have no issues using this as a beat around plinker, ranch gun optic, or competition optic if you don't want illumination. I did not want illumination and the added weight/complexity of a battery and electronics so I'm glad I went this route. So is my wallet.
