I came here looking for Longshot internals, only to find that Photobucket is being a little bitch.
So, with apologies to Captainslug and Wes7143, I present a new exploded Longshot image for your consideration - sans Scope, as I used this in another project already...
Important note: Nerfhaven uses an image crawler for linked images that saves them to the site. It does not do a good job linking them anywhere in the posts, but you can find the images in the upper right next to "Reply to This Topic" under the "image archive" link.
