Scan your surroundings with an enhanced view using the Vortex Viper PST Gen II 1 - 6 x 24 SFP MRAD Scope. ArmorTek® and XR™ coating keep the lenses antireflective and abrasion resistant, while the lenses themselves offer a high-definition image. O-rings prevent moisture and dust from doing damage, and the argon gas purging helps ensure the scope is fogproof. The rubber armor provides cushioning as well as a firm grip, and the shockproof design helps in case of recoil.
