I took 1-1/4†couplers and put them on 1-1/4†to ¾†reducer brushings and then cut off the excess. Not entirely necessary but it removed about ½†of dead space

And did this three times. The white lines are where I shaved down the outside so they would fit perfectly in such close proximity.

I originally tried the e-tape wrapping with Goop combination but in the first round I used it at a war the barrel couplings twisted right off the stock barrel stubs. So in my next attempt I used epoxy.

I put painters tape all over the face so I could epoxy the barrels as close to the base of the sally as possible but not have the actually ON the Sally.

In-process picture.

BAM! Tri-shotty Super Sally!

I could not get a fourth three shot attachment on the top, but 2 wraps of e-tape around a 4†length of ½†CPVC fit perfectly.

Field test result: I got 9 shots into the core in a DTC round in ONE SHOT at M.A.N.O. a few weeks ago! However, it basically sucked the butt at any other game type due to it’s slow reload time and rather random ranges.
Ranges: single shot gets 60’+, great for eliminating a core defender. Shotties get 30-45’ with streamlines, 10-50’ with Stephens.
Ways this could be easier:
• Don’t cut down the barrel couplers: most likely not a huge diff.
• Cut the stock barrels off AFTER you epoxy the barrel couplings on to make sure there is enough stock barrel material to epoxy to.
• Just epoxy the barrel couplings to the Sally face. Won’t open, but if you need to open the thing it is usually to scrap it for parts.
