Weird that B3-n/S1e2-a3-e4e is heavily lacking guns despite how common the t-ship is in that rule.

This is the only natural gun so far, which is useless due to the period being too low:

What are the state 5 cells for?

What are the state 5 cells for?

I used them to mark the bounding box of the gun (excluding the output glider stream). The gun is shown in the phase right before the output glider leaves the bounding box.

In addition to a natural p39 gun shooting p3 orthogonal c/3 gliders (which is the reason to post here), this cellular automaton features a natural p14 orthogonal 2c/7 backrake.

The backrake can also be used as a source of a p26 glider stream (moving away from some stationary pattern that consumes the glider stream).
Due to a lucky coincidence, 26:39 = 2:3 allowing glider streams from the gun and the backrake to interact with each other in predictable ways:

The thing on the right fails to be a p114 gun (or any gun, for that matter) in the specified cellular automaton. For all I know, that might be a case of accidentally putting patterns in two different cellular automata into one RLE without noticing that.

Is there a simpler design? I believe it is possible to construct a gun using the following overunity reaction (it would be p2596 as shown, but could be adjusted). However, two or more instances of the overunity reaction may be needed (or a different 2c/15o spaceship reflector):
