In some translations, it's called 'Carabineer'.

Buying any gun from Nimble triggers a side quest with Snag, who will attempt to take your gun away claiming it is his. You may or may not get this weapon on your first request. This weapon can only be purchased from Nimble, by asking for a close range weapon.

Although, unless one heavily weighs on the use of slug rounds than buckshot for medium-range combat where a SUSAT scope would have effective use, a sight mount is not all that necessary on a pure close-combat weapon as the iron sights are more than enough for aiming at narrow areas and very close targets. The only advantage the Eliminator has over the Carabiner is the fact that the latter cannot mount a SUSAT scope. The stock capacity has been increased from 8 to 10 shells, after upgrades it will have the same 12-round capacity as the Eliminator. The Carabiner also benefits from a considerably higher rate of fire (higher than any other shotgun in the game), therefore it is a great weapon to use against mutants. The main difference between a normal SPSA-14 and the Carabiner is the reduced recoil. The performance is comparable to the Eliminator.
