Up for sale is a genuine **Magpul PRS GEN3 Precision-Adjustable Stock**. Built for rifle-length receiver extension tubes (as well as Mil-Spec/Commercial carbines with the included adapter), this stock is the gold standard for precision AR10/AR15 builds, bolt guns, and long-range setups.

It is in excellent condition with no wear. I have 3 of these and mounted it on a safe queen for a few months then ended up pulling it off to go with a lighter weight fixed stock. All adjustment mechanisms—including the tool-less aluminum thumbwheels for length of pull and cheek height operate smoothly and lock up rock-solid.

Features of Note:

Adjustability: Tool-less adjustments for length of pull (up to 1.0") and cheek piece height (up to 0.8").
Durability: Enhanced rubber butt-pad with positive non-slip surface and robust aluminum detent knobs.
Mounting Options: Multiple sling attachment points, including a rotation-limited QD sling swivel mount (up to 1.5") and bottom M-LOK slots for a monopod.
Compatibility: Mounts on standard rifle-length receiver extensions without a buffer tube change, or can be adapted to many mil-spec carbine tubes.

What's Included:

  • Magpul PRS GEN3 Stock
  • Carbine and Rifle mounting adapters/hardware
  • Original box / instructions


PM me if you have any questions. Local pickup near me only. I'm not traveling far beyond the NKY Airport area. And yes, I'm FIRM on the price. This stock typically runs north of $260 so this is a fair ask.
