Thordsen Customs FRS-15 Gen III Stock Kit

The Thordsen Customs FRS-15 Gen III is the most complete single-purchase path to a featureless AR-15. Where a featureless grip removes only the pistol grip, the FRS-15 is a shell that slides over the buffer tube and replaces both the pistol grip and the adjustable or telescoping stock at once, presenting a fixed, rifle-style grasp and cheek weld with no protruding pistol grip and no collapsing mechanism. That matters because California Penal Code 30515 and New York Penal Law 265.00 each count a pistol grip and a folding or telescoping stock as separate defining features; the FRS-15 takes both off the table with one kit.

It is molded from 33% glass-filled nylon and ships with the spacers and hardware to fit a standard mil-spec AR-15 or AR-10 buffer tube. Length of pull is fixed once installed, which is the compliance trade: you give up the adjustability of a collapsible stock to clear the feature test. The Gen III revision improved the cheek weld geometry and grip-area ergonomics over earlier generations, and the Enhanced kit variant adds QD sling points for shooters who want them.

For a builder who wants to address grip and stock in one part rather than buying a featureless grip and a fixed stock separately, the FRS-15 is the efficient choice. It is priced like a mid-tier stock rather than a budget grip because it is doing two jobs. Combine it with a non-flash-hiding muzzle device and 10-round magazines to complete a compliant configuration in a magazine-capacity-restricted state.
