Vector Arms V51 / Heckler & Koch 7.62x51mm Semi-Auto Short Barrel Rifle, Sear Ready Host


Status: In-Stock / Please Call to Purchase

This Chester County Armory listing is for a factory Vector Arms V51 semi-automatic 7.62x51mm NATO NFA short barrel rifle that is setup as a sear ready host gun.

This model was built by Vector Arms of North Salt Lake, UT using a PTR-91 receiver and uses an original Heckler & Koch G3 full auto bolt carrier, along with an H&K SEF Navy style polymer grip and three position selector already installed. This SBR is all set for you to be able to drop-in your NFA registered SEF sear or trigger pack, or attach your own shelf model trigger housing, as desired.  This weapon is in overall excellent condition, with only minor wear noted on the BCG group and firearm control internals.  Mechanically, this weapon is in excellent condition with no operational concerns, whatsoever. The bore remains bright and shiny with crisp, clean rifling. Cosmetically, this model displays minimal handling and use marks in the original exterior metal finish. The polymer furniture is also in excellent condition, with only limited handling marks observed.

This NFA registered semi-automatic short-barrel rifle is currently on a Form 3, with “Vector Arms” listed as the manufacturer and “V51” listed as the model.
