ForSale: Selling my .357 bullpup. It has a shroud adapter and m18 threaded Neil Clague moderator (which is a very nice custom .357 moderator worth $175). It has a regulator also but I can only get the reg to to work at the lowest setting, at which it will only shoot around 600 fps. So I just set it on the higher end where it does not regulate the psi at all but does essentially act as a good plenum. I swapped out the original hammer preload spring and with this lighter spring it shoots an excellent shot string (8 shots in a bell curve from around 855 up to 895 then back to 855 fps with 90 grain zan slugs - from 3300 down to 2300 psi. With the original spring you can fill it up to a much higher psi and it will put out a lot more power but it just has a steadily decreasing shot string with the heavy spring since the spring is very strong and easily overcomes the valve pressure (maybe it would get a bell curve at the high end of the max fill - something close to 4500 psi - with the right ammo combo….but don’t know….i never took it over 3600 psi as I was not looking to use this for larger game). Comes with 2 rotary magazines (125 gr Zan slugs are a smidge too long for the mags but can be loaded individually pretty easily). I have probably around seventy-five 81 gr jsb pellets and around ninety 125gr zan slugs, and I think maybe eight or nine 90 gr zan slugs. It actually shoots the slugs better than the pellets (probably needs an even lighter spring for the pellets since they are still going well over 900 FPS with the lighter spring I currently have installed). I originally bought the gun because I wanted to have my siteMark wraith camera/scope installed on one gun to hunt everything with so I didn’t have to rezero and swap around but with this heavy hammer/trigger, I really cannot seem to get really tight groups at 50-75 yards for things like rabbit/squirrel headshots, starlings, pigeons, crows. Great gun for larger game though with a lot of power potential!
