Overview

This cheekpiece is designed for use with all variants of the B5 Collapsible Precision Stock, giving shooters a simple way to fine-tune cheek placement. It mounts and adjusts through the stock’s undercuts and adds 3/8" of height along with horizontal adjustment to help set a more consistent position. A soft overmold adds comfort, while the Mil-Spec materials and finish keep the design straightforward and purpose-built. At 2.00 oz., it adds a small amount of weight without changing the stock’s overall profile much.

  • Mounts and adjusts through the CPS undercuts for a secure fit.
  • Adds 3/8 inch of height and horizontal adjustment for cheek placement.

Considerations & Trade-offs

  • Fits all variants of the B5 Collapsible Precision Stock (CPS), so it is not a universal cheek piece for other stock systems.
  • Adds 3/8" of height plus horizontal adjustment, which may be helpful for cheek placement but also changes the stock's original feel and setup.
  • Uses a soft overmold for comfort, but that comfort-focused surface may be a different preference than a harder, more minimal contact point.
  • At 2.00 oz. and 4.50 in. long, it adds some size and weight to the stock assembly, which may matter for users trying to keep the setup as light and compact as possible.
