Synoid Gammacor http://warframe-builder.com/Seconda...6-6-543-6-195-6-209-11-487-8-605-7/en/3-0-55/ Vaykor Marelok http://warframe-builder.com/Seconda...06-6-543-6-195-6-209-11-487-8-605-7/en/3-0-53 While the weapon range of these two weapons is vastly different, they both share excellent accuracy. The Gammacor has a clear advantage in terms of raw DPS, but it has significantly shorter range compared to the Marelok. If you need a pocket sniper, the Marelok is hard to beat (especially if you like getting head shots). If you need a spammier short range backup weapon, the Gammacor is very lethal. NOTE: The above builds include Primed Pistol Gambit and Primed Target Cracker, but are certainly not required for the weapons to perform well.
