Of corse you can they are the most typical nerf gun they are everywhere even at toys r us!!!
Yes the recon is still available it is a very common nerf gun
On the top of the Recon CS-6 there is a tactical rail (look it up if you are not familiar with it) where the sight can be attached.
There is no such nerf gun as the n-strike cs6. But a how-to on modifying any nerf gun can be found on youtube.
There are two: The 2010 N-Strike Stampede ECS and the 2000 Power Nerf Ballzooka MP150.
The Nerf recon cs6 is a Nerf gun that has 5 different accessories that can make the gun look like a :shotgun, pistol, machine gun, and other types of guns. It comes with a stock, flip up sight, light, a barrel extension, and a clip with 6 darts. it can only shoot streamline darts and you can buy it for $20.
17
5 in total. The gun, the detachable barrel (shoots better without it), the shoulder stock, the flip-up sight, and the lazer target.
a chain gun
the bootleg gun
same way you would mod any other Nerf gun
sometimes the nerf dart can get stuck in the barrel, but can be taken out easily with a pencil or something like that, but otherwise a great gun!
It depends what you like. i would say the recon or the vulcan.
