The Classic Army FN SCAR-L Sportline AEG is a great airsoft option for those that want to use the VERY common M4 style magazines but don't want another M4. This rifle is very solid right out of the box. The SCAR-L features a 6 position stock with a 2 position cheek riser that allows for customizable comfort. The stock can also be folded to the side for easier usage in CQB or storage. Metal flip front and rear sights come standard. Top rail is plastic, but the side rails are metal. The SCAR-L is a great addition to anyone's airsoft armory. Every though it's a "sportline" airsoft gun, this SCAR is built really nicely and looks excellent too!
