Yes, all of it.

Well, This is it. This is my entire halo arsenal. Yes, all of it.
I have built every halo weapon that can be built. In other words, everything but the beam rifle. The beam rifle, you see, cannot be built. There are two of every dual-wield weapon and a couple of object you might not recognize. Next to the sniper rifle is the Spotter Scope. Near as I can tell, it is seen only three times throughout the halo trilogy (twice in Halo 2, once in Halo 3). In the far upper right is the laser tracker. It is seen only in the Halo Landfall live action short film. It was used to track the 'Chief's atmospheric reentry into the jungles of East Africa.
