## Description

Rob Allen now introduces the Vecta, a new state of the art gun handle. The Vecta is the result of three years of research and development into creating the ultimate speargun trigger mechanism and grip. This development is set to elevate the status of Rob Allen's core piece of equipment, the Railgun, to an even higher level. The result of all this engineering is the Vecta, the strongest, smoothest and most robust mechanism available. Railguns are unique in the sense that they have an extended "rail" incorporated into the aluminum barrel for the full length of the shaft. This rail supports the spear the full length of the barrel and continues on into the muzzle. The rail barrel tube is also much stiffer and stronger than a normal tube because it is thicker-walled and has a slightly bigger diameter. The integrated rail adds further strength. Rob Allen also uses aircraft grade aluminum when the barrels are extruded. This gives the barrel even better strength and stiffness, enabling it to handle strong rubbers and be used in longer lengths without flexing. It is basically stronger and stiffer than wood of the same diameter.

Rob Allen aluminium railbarrels have the same dimension as the carbon barrels. The rail level lines up with the profile of the mechanism and the muzzle. The integral rail is part of the barrel, thus increasing stiffness and reducing flex. This makes the guns deadly accurate.

The rail barrel is manufactured from aircraft grade aluminium with a wall thickness of 1.45mm and the mechanism is manufactured from glass reinforced nylon and has a solid 316 stainless steel sear.

I sell all Rob Allen Tuna guns with their new OPEN MUZZLE, 7mm shafts and two 5/8" (16mm) bands.
