Hatsan Bullmaster Modifications

[SpindleB]

I've adjusted my .25 Hatsan Bullmaster a tad.
1.1l air cylinder
Huben Power Dream Universal (175 bar) Regulator
Shroud mounted long bipod
Bottom side picatinny rail
Picatinny to Arca adapter

No clue how many shots I can get with this setup. I can go through 6 magazines and still have over 4000psi.

Given how heavy it started and how much weight I added the Arca and Tripod are just about a requirement for this old man to shoot this rifle

And the modular moderator from Buck Rail. Works as good or better than the DFL Sumo that I had on there at less than 1/2 the price of the Sumo

Did u change it to take a bottle, an regulator that allow higher psi?

Yes, Huben Power Dream Universal Regulator. Drop block allows a larger diameter bottle to be used. Up to *some* 2L bottles. I'm using a Tuxing 1.1L.

To use the Dream regulator requires cutting a section of the fore stock off. Just forward of the hand grip.
