I would recommend changing out the stock and pistol grip.

Any AR-15 milspec stocks will work. I like the Magpul CTR and Magpul MOE SL. No rattle, easy to adjust, look cool and most important more comfortable.

For grips I really like the LaRue A-PEG from Larue Tactical. Only $10 and very comfortable.

Another great upgrade if you will be carrying the rifle is a good two point sling. I like the push button QD attachments.

Like others have said, shoot it.
Shoot it again and then shoot it some more. You may find that you like it right out of the box.
