Build Quality – Durability
Made of high-quality materials, the Viper S400 will make a lot of difference in terms of durability and you will be able to use it for a long time due to some important features that increase its lifespan.
The rail is made of aluminum and the MICO-TRAC barrel reduces friction because it measures only 17”. This way, the area of the flight deck is reduced in half. By using this design, TenPoint has increased the lifespan of the strings and you will be able to use them for as many as 1300 shots.
Design
Even if it is a little bit pricier than its competitors, the Viper S400 has just 7.2” between the axles when cocked, which increases balance and improves maneuverability in order for you to be able to enjoy great performance in all tight shooting situations. The graphite gray print will easily blend with your surroundings.
The stock size is minimized in order to increase performance due to the crossbow’s weight which is reduced by half a pound.
Speed and Performance
The Viper S400 is one of the most performant products when it comes to speed, as it can reach a maximum of 400 fps which will also increase precision. The zero-creep design of the S1 trigger as well as its smoothness will ensure great performance and will allow you to reach your target very easily.
The S1 trigger is known to provide better control which, together with the weight of the crossbow and with the fact that it is narrow, it will increase the success of your shots.
Accuracy
Along with the Vengent S440, the Viper S400 is known to be one of the most accurate TenPoint crossbows. This precision is achieved by a few factors that are combined in order for you to be easier to hit your target.
Firstly, it is very easy to maneuver because it gives you great balance and you will be able to precisely aim at your target. The speed is a factor that increases accuracy and, together with the Vector Quad technology, which is able to reduce cam lean, ensures accurate shots.
Safety
It is very easy to get hurt when you de-cock your crossbow, and this is why TenPoint has come with the ACUslide mechanism which is known to be the safest way to cock and de-cock such a weapon because it simplifies the process.
The S1 trigger also provides high safety levels because it comes with a Dry Fire Inhibitor. The safety wings made of nylon will prevent you from injuring your hands by not allowing you to place them in the area where the strings are moving.
Noise and Vibration
We know that we have talked about the ACUslide mechanism in the safety section of this article, but another great thing about this mechanism is that it makes the cocking silent. The narrow design and the fact that string friction to the rail is minimized also reduces vibration, placing this crossbow among the top when it comes to silent crossbows.
Ease Of Use and Assembly
There is a lot to say about the Viper S400 in terms of ease of use. First of all, the weight of the product makes it very easy to balance and hold for longer periods of time. The fact that it is narrow when cocked also helps you to easily balance the crossbow.
If we go deeper into details, it is important to mention that the ACUslide mechanism also has a lot to do with it. By using 2 rollers made of stainless steel, it will help you cock and de-cock the crossbow by backwinding the handle while being able to stop anytime without having to worry about safety.
The package includes everything you need to start shooting after you assemble the crossbow and you will be able to do that very quickly because most of it is already put together.
Viper S400 Review Summary
The Viper S400 is a crossbow that takes shooting to another level and you will not want to go back after using it. While offering exceptional safety features, this crossbow also comes with astonishing accuracy that is partly due to the high speed and also to the systems used in order to make precision better, like the Vector Quad Cable System.
The RX-6 cams improve down-range precision and, overall, this is an outstanding product when it comes to quality and durability as all of its parts are made of high-quality materials that will allow you to use it for a very long period of time.
