As compared to the SNAP-1 mk1, it loses an inch or so in PC length. (Dig the hot pink clothespin.)
It looks positively diminuative against a SNAP-1.
Here's the plunger:
And here's the plunger head.
The nice thing about this system is that it comes apart in about 15 seconds with only a screwdriver. The part on the far left is a compression nut (rubber tube with a nut in it). This one is a #10 x 1". The washer gives support to the rubber fender washer.
Here's a close-up of the plunger assembly:
The other space-saving thing is cutting down my usual .75" endcap catchface. to just the rear .25" or so. The compression nut I used for this was 1" long, so that was why I had to place it as far back as I did...a shorter compression nut would equal a shorter plunger head assembly.
(Made another "duh" sort of discovery while assembling this gun: in the past, I've fussed around with nail length to try and get it at the proper depth with the pin at full close. This time, I realized that you could shim the jaws of the pin to control how deep the nail goes. I gave the nail a rough trim, then added a bit of plastic in the pin jaws to control depth.)
As far as ranges, there seems to be no real gain or loss with this design. I did some quick outdoor testing today (light breeze, nothing major), and averaged 83 feet with my breech barrel....so the major gain here seems to be in a smaller size. Identical power in a smaller package? I'll take that.
