"looks like this...
all in all I have maybe 450 bucks into it total..."
That will work but, suggestion:
You really should invest a little more $$$ into your optic. NC Star (first of all) is not a holographic weapon sight. It is just an illuminated red dot optic and not a very good one at that.
EOTech is the only true Holographic (& also the Bushnell Holosight which is actually made by EOTech) - (secondly) NC Star is pretty much nothing more than AIRSOFT OPTICAL Grade and were I you...I sure wouldn't bet my bacon on it.
