Looking at the CT MVF-515 in either green or red for my new AR Carbine I just finished building. Has anybody had any experience with this product. I have SEVERAL CT lasers on other guns, so I am sure the quality is right there with the one I have. Just looking for over all opinions. For the flat top (removable handle) I am looking at an EoTech 512. Combination could make this a FUN little gun.
