Get a bunch of Tapco/Mako tactical stuff and attach something, everywhere. What do looks have to do w/ it? Does it shoot well? Is there anything you think would help you get on target faster? Anything you think would help its performance?
I agree with Mike, most of the "tactical" add-ons you see in magazines are crap. I'd look at getting more quality magazines and a good sling. Then maybe a good optic.
The biggest issue with assembling an AR isn't so much getting the parts together right - it's getting the right parts together.
You'll remember the quality of a gun long after you forget how much you paid for it.
