I recommend Magpul, you'll have to buy F&R separately.

Donald, for flip up iron sights I'd highly recommend Magpul mbus sights. They're one of the best available without costing an arm and a leg. Here's a link to the rear sight if interested.......................... budsgunshop.com/product_info.php/products_id/1132/magpul+mag248-blk+rear+mbus+gen+ii+black .......................... And here's a link to the front sight........................... budsgunshop.com/product_info.php/products_id/1135/magpul+mag247-blk+front+mbus+gen+ii+black ............................. If you would prefer a scope here's a link to a Bushnell 1-4 ar optic specifically designed for AR-15s Wich is a fantastic scope for the price.......................... budsgunshop.com/product_info.php/products_id/104969/bushnell+ar71424+ar+optics+1-4x24+obj+112-27+ft+@+100+yds+fov+30mm+tube+dia+black+matte+drop+zone+223 ...................... Hope this helps.

Myself, I prefer the MagPul MBUS sights. Easy to adjust and co-witness with a good red dot optic. Here's a link to them here at Bud's.
