Fab Defense RAPS Rapid Adjustable Precision Stock, Collapsible, Black (FX-RAPSCB)

The Fab Defense RAPS Rapid Adjustable Precision Stock is a collapsible rifle stock built for shooters who demand precision and versatility without the bulk. Whether you're running precision drills at the range, hunting from various positions, or setting up for long-distance work, the RAPS-C combines a compact, lightweight design with the kind of adjustment range you need to dial in your perfect fit. It bolts onto any standard carbine buffer tube—no gunsmith required—making it an easy upgrade to AR-15 platform rifles and compatible clones.

What sets the RAPS-C apart is its integrated cheek rest and dual-stage length-of-pull adjustment. You get macro adjustment via the buffer tube itself and fine-tuning through the patent-pending RAPS system, all controlled by a single latch that locks both the butt-pad height and cheek position simultaneously. The built-in memory function means once you dial in your length of pull, the adjustable pad springs back to that exact position every time you collapse and extend the stock—no fumbling or re-measuring at the range. The latch works for both right- and left-hand shooters, so southpaws aren't left out of the precision game.

The stock includes a heavy-duty rubber butt-pad with its own height adjustment, a concealed Picatinny rail underneath for monopod mounting, and a retention bolt that works with both MIL-Spec and Commercial-Spec buffer tubes. The black finish is durable and low-profile. For shooters who refuse to compromise between portability and adjustability, the RAPS-C delivers competition-grade features in a no-nonsense package.
