The top release mechanism of the Salvimar range, the new Roller muzzle, a truly refined shaft and a length, 105 is the speargun we received, make the Salvimar Metal Roller an accessible, but still performing product.

Handle and release mechanism

It is the same handle as the Salvimar Metal Krypsis, except for the color of the 30% glass loaded Nylon, which in the latter is a purple color, while here it is a traditional black. 

The handle has an anatomical left and right-hander design and is made of 30% glass loaded nylon, just as the muzzle, and has a special softer anti-slip light green color, the traditional Salvimar acid green, element on the backside where the palm of the hand adheres. There is no “wing” that permits to best position the line away from the line of aim. The handle is designed to mount any Salvimar Reel. In the bottom part of the grip, there is a well-designed and integrated passage, one piece with the grip, for positioning a line. In the rear part of the handle, a well-shaped and good dimensions dismountable gun butt is present.

The release mechanism is the key element of this sling speargun. First of all the release mechanism is made of 100% 304 stainless steel, including the castle and the trigger. Moreover, the steel structure (box) containing the release mechanism has been thickened to improve rigidity and resistance. In addition, another key element of the system is the fact that both sear and trigger are produced using MIM (Metal Injection Moulding technology), which permits to obtain amazingly precise components and a very beautiful trigger. And more: the sear is complete with a roller wheel made of 17-4PH stainless steel thermally treated for best superficial hardness and resistance to load and wear. This roller wheel avoids one of the main problems with metal to metal contact of the sear and the trigger, that after a certain time of use (depending on the quality and superficial hardness of the metal) tend to wear, change the angles of contact and finally modify the hardness of the trigger when shooting. The roller wheel avoids this and has the aim to smoothen the trigger movement in the shot, improving the precision of the shot itself. All this permits to have a max load capacity of 350 Kg.

The line release lever is in the modern and most efficient lateral position and it is also made of steel, always a good solution to resist wear and deformation. Such a lever can be quite easily moved from the right to the left side of the handle. In addition, the sensitivity of the trigger can be regulated with a screw positioned under the hilt.

The security system is positioned in such a way that the right-handers can feel the “button” coming out of the handle signaling the lock is on. This works also for left-handers, but is a little less effective are they will feel nothing and from that will need to understand the lock is on, and when the lock will be off they will feel in the palm at the base of the index finder the “button” of the lock coming out.

Barrel

The barrel is made with 28 mm external diameter anodized aeronautical aluminum tube and integrated shaft guide. The wall thickness of the barrel tube is 1.3 mm. The water tightness of the connection between the muzzle, barrel and handle is made with double O-rings. The barrel is black anodized. The available lengths are 60, 75, 85, 95, 105, 115 and 125 cm.

Muzzle and elastic bands

Salvimar Metal Roller has a very specific muzzle with a wide 30% glass loaded Nylon structure holding the two pulleys of the roller system, which are highly flowable thanks to Derlin® material. The innovative design of the roller muzzle with upper “V” opening facilitates the insertion of the rod with fins during the loading phase. The passing of the line on the roller muzzle for fastening the rod is quick and intuitive thanks to the upper channels. There are three passages for the line, two lateral ones and an inferior one, both in stainless steel wire.

Elastic bands are two for the roller system and of 17.5 mm diameter and 3.3 elomgation coefficient, even though the muzzle has pulleys compatible with elastic bands of up to 18 mm diameter. 

The list price of the Salvimar Metal Roller starts from € 239 for the minimum length of 60 cm, up to € 279 for the longest 125 cm, so it fits perfectly into the € 200-300 price range, even if the most interesting lengths are definitely starting from 85 cm.
