Kral Arms Puncher Jumbo Regulator By Huma-Air

Huma-Air External Tuning Regulator For Kral Puncher Jumbo

This External PCP Regulator build by Huma-Air is specialy designed for the Kral Arms Puncher Jumbo.

The tuning regulator will reduce the outgoing pressure of your rifle’s pressure bottle according to your settings and this will result in a constant pelletspeed and better groups. It is equipped with a pressure gauge what will indicate the fill pressure of the bottle and a foster male connection to fill the rifle. The position of the gauge and and foster can be chosen left or right and they can be aligned stepless into their position so it always looks good on your rifle.
We tested the Kral Puncher Jumbo .25 (6.35mm) model, with a regulator output pressure of 140 bar shooting 33 grain pellets at a speed 950 fps. (The regulator output pressure can be set higher) 925 fps for 21 grain slugs and 1030fps with 18.1 grain pellets.

When the tuning regulator is fitted to the rifle you can read the regulator output pressure on your rifles’s pressure gauge and the fill pressure will be shown on the regulator gauge. Pressure can be set by turning the set-screw of the regulator what can be found inside the male treaded part of the regulator. A 5 minutes turn contra clockwise equals to about 6-7 bar pressure increase. This bottle regulator will be screwed in between the pressure bottle and the action of the rifle. It will ad about 58 mm of lenght.
(your original rifle’s fill connection is replaced by the regulators quick connect foster male fill connection. Do not use the original rifle bottle fill connection anymore)

The benefits of this Huma-Air, Kral Arms Puncher Jumbo tuning regulator are:

• It will give you a better shotcount and a full flat shotstring immediately.
• Higher accuracy due to the elimination of the pelletspeed fluctuations
• The solid stainless steel foster fill connection and pressure gauge can switched over from left to right
