Guns in life-like cellular automata
Due to the small speed-of-light spaceships in many of the rules with B2, it is somewhat trivial to find low-period guns in these rules. I think it would be infeasible to keep track of all of the B2 rules that contain guns on this page. The 'Guns in Life-like cellular automata' section should probably say something along these lines: "Due to some small spaceships in life-like cellular automata with birth at two cells (B2) many low-period spaceship guns have been found using tools such as WinLifeSearch. In contrast, there are very few rules without B2 that are known to contain guns. The following is a list of rules without B2 that have known guns: ..."

I'm not sure if LWSS (MWSS, HWSS...) guns should be noted in the section "other guns"; they might deserve a separate listing... or a footnote to the glider section, since I presume most of those are based on the 3-glider synthesis. Any rule with small spaceships like the glider is bound to have glider constructions for various objects, so it doesn't seem to me that having glider-compounding guns is a particularly interesting fact about a rule. Gliderless guns are known for Life itself however, as well as for HighLife.
Also, the B37 rules must be something else than LWSS guns; would that be guns firing "Rderships", a slip of the finger, or something else? (Some general sourcing wouldn't hurt, either.) --Tropylium 06:16, 19 September 2011 (CDT)
True-period gun credits
The list of credits for true-period guns is difficult to read. I suggest replacing it with a table, like the one on the oscillator page. It could look something like this:
Arrangement of guns
I found a P60 glider gun where two Simkin glider guns delete every other glider from a Gosper glider gun.
