Roller gun

 * – ( View AfD View log  Stats )

This isn't a class[ification] of firearms that can be sourced, and the title is pretty misleading as well. I was expecting this to be abut roller-delayed blowback. However, looking at the first image, what was intended by this article is to cover the use of a [rotary] feed sprocket, which is found in a good number of machine guns. Information about the various feed systems and their classification should be included in machine gun (see Chinn, vol. 4, chapt. 5), but this article has no useful material to merge.

 * Redirect to Speargun - all I could find on almighty Google was "roller spearguns", which this article has a hatnote for. It's more conceivable that someone could be looking for that than a WP:NEO class of machine guns. Ansh666 06:53, 23 July 2013 (UTC)


 * Delete. This page seems pointless. It appears that it was created for the sole purpose of linking to other pages. None of which are notable and are on the verge of being deleted themselves.--RAF910 (talk) 13:48, 23 July 2013 (UTC)


 * Looking at the mixture given in the example section, this article also confuses a couple of issues, namely the sprocket-type feed mechanism (although the ShKAS is somewhat more elaborate than that because its "squirrel cage" also cams the rounds along the axis of the barrel) with the so-called split-breech or "nutcracker" breech design, which is perhaps even more obscure; the latter has only been used successfully in low pressure applications such as the Mk 18 Mod 0 grenade launcher cf., which is unfortunately not given as an example here. (The Fokker-Leimberger, which attempted to use this principle in a high-RPM machine gun had unsolvable problems with ruptured cases. The other two examples of this kind from the article, the Johnston machine gun and the Hodges machine gun are basically just patents). I've not been able to locate a good source for the internals of the obscure Soviet Savin-Narov machine gun, but given its external aspect, it's likely it doesn't use a "nutcracker" design.

 * I've written a paragraph about this "nutcracker" breech design in our (rather undeveloped) general article about breechblocks given the unclear scope of breech mechanism. Given the obscurity of this design I'm not going to put it in a separate stub. There's too much fragmentation in this topic area anyway.
