Overview

This spacer is designed to help fine-tune stock pitch and length of pull without modifying the stock itself, making it a practical option for hunters dialing in fit for a more consistent shoulder mount. Its tapered profile supports both negative and positive adjustment, while the slotted holes are intended to provide a universal fit.

Considerations & Trade-offs

  • Designed for stock pitch and length-of-pull adjustment, so it’s a fitment part rather than a performance upgrade.
  • The slotted-hole, universal-fit layout may still require checking hole spacing and alignment before installation.
  • Its black polymer construction is practical, but the product data does not indicate any added cushioning or recoil-damping benefit.
  • The spacer is offered in tapered positive/negative options, so selecting the wrong taper could affect the final stock fit.
