The R3 is now available, a smaller more compact, stronger model. Compatible with 12, 14,16 and 18mm rubbers to provide accurate shooting up to two wraps.

It comes in both open and closed versions to allow for personal preference. There are two different bore diameters 25.4mm and 25.9mm for different dimension of tubes. You are able to purchase the Roller muzzle on its own at $119 or you can order the roller kit for $149. Roller Kit: Rubber of your choice, dyneema set up.

Idea Behind the roller:Roller heads are not a new concept they have just been refined through becoming more compact and improved the ease of use. The rubber on a roller gun runs from an anchor on the bottom base of the tube or the handle, to the muzzle, through the roller system and down to the notches on the spear. The purpose of this is you are able to change the tension of the rubbers by simply winding more line around the anchor and intern stretching the rubbers. There is a dyneema bridge between the rubber at the wishbone to stop the rubber going to far backwards through the roller when fired. On a conventional gun the rubber go slack or stop 36 – 18cm away from the muzzle (depending on length of rubber). Where as on a roller gun the rubber travels all the way to the muzzle as it’s pretensioned before loading. The rubber is therefore pulling the spear for a longer period of time transferring more energy. In theory the longer the rubber carries the spear the further it will travel. Having the rubber pretensioned means the rubber can fire the spear at it’s optimum elasticity and at no point goes slack. As the rubber pulls the shaft on top on the barrel it is running the opposite way on the bottom cancelling itself out and reducing recoil and stress on the barrel. The roller head can substitute the need for two rubbers while not sacrificing accuracy.
