Basically all this mod does is replace the mesh of the recon scope with the long scope.  I hated the look of the recon scope, and even with retextures, it still looks out of place.  This mod gives it the long scope mesh to make it feel a little bit more consistent with the general aesthetic.

Now replaces all Recon Scopes!  Also, now it's all contained in one pretty little esp file, which means that any texture mods applied to your long scopes also apply to your recon scopes!

I made another mod very similar to this one!  Check it out:
Sniper Barrel to Auto Barrel Mesh (Laser Rifle)
