I tried out the compression nut-based plunger in a full-size SNAP last night, and the results are pretty favorable. The main benefit seems to be packing the same amount of power in a smaller package.

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.

Very nice!!!


I will definately use this when I build my SNAP.



And I think by now we should consider additions to the SNAPs as modifications, simply because of how much they are changed and how much better they can be made.


Nice job!

Compression nuts... Shit that'd make producing plunger heads so much easier. Very nice job Carbon! Glad to see you're still making progress on the SNAP series.
