Agkistrodon piscivorus

Agkistrodon piscivorus is a venomous snake, a species of pit viper, found in the southeastern United States. Adults are large and capable of delivering a painful and potentially fatal bite. When antagonized, they will stand their ground by coiling their bodies and displaying their fangs. Although their aggression has been exaggerated, individuals may bite when feeling threatened or being handled. This is the world's only semiaquatic viper, usually found in or near water, particularly in slow-moving and shallow lakes, streams, and marshes. The snake is a strong swimmer and will even enter the sea. It has successfully colonized islands off both the Atlantic and Gulf coasts.

The generic name is derived from the Greek words ancistro (hooked) and odon (tooth), and the specific name comes from the Latin piscis (fish) and voro (to eat); thus, the scientific name translates into “hooked-tooth fish-eater”. Common names include variants on water moccasin, swamp moccasin, black moccasin, cottonmouth, gapper, or simply viper. Many of the common names refer to the threat display, where this species will often stand its ground and gape at an intruder, exposing the white lining of its mouth. Three subspecies are currently recognized, including the nominate subspecies described here. Its diet consists mainly of fish and frogs but is otherwise highly varied and, uniquely, has even been reported to include carrion.

Rap GTP-binding protein

Rap GTP-binding protein also known as Ras-related proteins or simply RAP is a type of small GTPase, similar in structure to Ras.

These proteins share approximately 50% amino acid identity with the classical RAS proteins and have numerous structural features in common. The most striking difference between RAP proteins and RAS proteins resides in their 61st amino acid: glutamine in RAS is replaced by threonine in RAP proteins. RAP counteracts the mitogenic function of RAS because it can interact with RAS GAPs and RAF in a competitive manner.

RAP99

The RAM P99 is a paintball marker manufactured by Chinese company Qian Wei and distributed in the United States by Umarex USA under the "Real Action Markers" brand. It is distributed in Europe by Umarex, Germany. The RAM P99 is made under license and designed to replicate the Walther P99.

Operation

Powered by a 12g disposable CO₂ cartridge or re-fillable internal air system, it features a blowback design and 9 shot capacity magazine using .43 caliber paintballs or rubberballs. The trigger is double-action (DA/SA). First versions did not have a conventional on/off safety. Current versions now have a manual trigger-lock safety. The marker is cocked by working the slide and there is also a functional de-cocker. It differs from the RAP4/5 system as it does not use (and therefore) eject shell casings. Muzzle velocity is adjustable between 200 ft/s and 300 ft/s. For .43 cal paintball - 0.029 oz it is about 3.4371 J (at 300 ft/s).

Use

The RAM P99 looks, feels and shoots with great accuracy just like the Walther P99 firearm making it ideal for law enforcement and military training, especially close quarter battles and room clearings. The RAM P99 is also used for virtual reality paintball play.
