Welcome. Since you decided on a Bushmaster, you already chose a great weapon. It's always better to get an AR with iron sights and learn how to use them before you add any accessories. This is probably the most important lesson next to safety. Bells and whistles are cool, but be aware that they can and will fail, so you need a basic foundation with iron sights to fall back on when necessary. The modular rifle is a sweet weapon, albeit a little pricey. The Bushy A3 16" model with a removable carry is another weapon to consider. I recommend the 16" over the Varminter for a first AR. It's lighter and easier to handle, also making it a better choice for a defense/bug-out weapon. Actually I prefer a standard iron sighted 20" A2/A3 setup for this role, but I see you are set on a 16". Carry handles are available [url=http://bushmaster.com/shopping/uppers/9349063-9.asp]HERE[/url] for $99. Good luck.
