Evanix Rainstorm II Baffle Stack
$35.00

Evanix Rainstorm II Baffle Stack

Here is an 8 piece multi-sized baffle stack for the Evanix Rainstorm/Rainstorm II. The HP Baffle Stack strips away turbulent air and sound from the shot signature of the Umarex Gauntlet. The baffles trap sound and air in each cavity and force it to stay in the moderator chamber away from the pellet path.
The Rainstorm HP Baffle Stack requires the non cone STAND OFF to be sized by the user. You will need to sand the STAND OFF down to the required height for your rifle.
The HP Baffle Stack should be installed as follows, from the front, further-est from the barrel, Short/Full/Full/Short/Short/Full/Full/Standoff at the muzzle.

Baffles should be pointing towards the breech

HP Stak Pak for Hatsan QE
Rated 5.00 out of 5
Original price was: $39.99.Current price is: $35.00.

Stak Pak for Hatsan QE shrouds (.357 & .457 Not Included)

Simply unscrew your shroud end cap, remove the two felt-covered stock baffle assemblies, remove the two aluminum stand-off chambers, and install the Hajimoto Stak Pak. No tools, no modifications, just a simple one-for-one swap! Some model Hatsans will use all the baffles others will need one less full-sized baffle, be sure to use both shorter baffles and leave out the full-sized one. If you need to leave one out, leave out the very first full-sized baffle and then arrange the stack as shown in the packaging.

A ten-piece kit that directly replaces the two hair curler style baffles that come inside any Hatsan that has a QE shroud system, excluding .357 & .457 models. The bundle has nine baffle chambers to help remove both noise and turbulence in the air stream. The baffle stack rides on a high tension compression spring allowing for a perfect fit for any Hatsan QE PCP, excluding .357 & .457 models.

The end result is a more laminar air stream which reduces projectile instability and substantially changes the sound of the report of the rifle. This kit is 100% compatible with the stock end cap or the DonnyFL A24 adapter.
