A 3mm fully automatic needlegun, and it's high-powered electrothermal counterpart. Both from Technomancy Designs. Stats for CP2020, CP3 and SR4.

Technomancy Design "Tsugaru" 

CP2020: SMG • +0 • J • P • 2d6 (3mm needle) • 60 • 3/30 • ST • 150m • 700eb
SR4: SMG • 4P • -3 • BF/FA • - • 60(c) • 5R • 600Y

The Tsugaru is one of the two 'base model' 3mm needle weapons on the market, competing against the larger frame (and greater ammo capacity) Malorian Rapid Needler. The Tsugaru is a burst-fire only weapon, with two fire modes - three shot burst and full autofire. The design is faily simple except for the magazine feed, which uses a front-loading magazine of 60 3mm needle rounds. Longer magazines can be used, but the extend past the barrel of the weapon. The Tsugaru also has a folding foregrip which can be used as an assault grip when folded out, or a regular grip when not. The Tsugaru is sold with a shoulder sling and half-hoster combination that allows it to be tucked unobtrussively under most jackets.

Technomancy Design "Assassin"

After seeing an Arasaka prototype rifle firing electrothermal 3mm rounds, the Technomancy team broke out the old Tsugaru and modified it to be a semi-automatic firearm, added the electronics for electrothermal firing, and then added a silencer, stock and sighting rail to the standard body of the weapon. The end result is a functional street assassination weapon that fits in a very small case (when folded and with the silencer removed, the Assassin has the same Jacket concealability as the basic Tsugaru). When combined with armor defeating water triggered explosive or armor defeating toxin ammunition, the Assassin can breach just about any known body armor to deliver a deadly payload.
