Decent laser/sight combo for the money - NcSTAR AR15 Green Laser w/A2 Iron Front Sight Post

Got this to add to a Radical Firearms Socom upper. The upper needed a front sight, and I like the green laser, so it seemed like no brainer, especially since I scored a good deal on it at $45 shipped.
First impressions are mixed. 1) It’s heavy, adding 1/4 pound to the very front of your rifle. 2) The laser’s windage and elevation adjustment screws are located on the front, inside the screw-on bezel, and are really a PITA to adjust. AND since you have to remove the front portion of the laser to change the battery, it looks like a rezeroing will be required any time you do just that. 3) Fit and finish? :-( When I first tried sliding it on the top rail it would get hung up and approximately 1/2 of it was hanging off the front of the rail. Seems there were a couple of small aluminum (pointed and sharp I might add) pieces protruding on the underside which kept it from sliding back. Once I knocked them off I was able to position the sight where I wanted. 4) It looks good mounted on the rail. Not nearly as gaudy as I was afraid it might.
The upper is 5.56, so the recoil shouldn’t be so bad that it throws the laser out of zero. Unfortunately I haven’t been able to get to the range since this arrived, but as soon as I do I’ll update this review.
