Considerations & Trade-offs

  • Designed for stock pitch and length-of-pull adjustment, so it’s a fitment accessory rather than a performance upgrade on its own.
  • The slotted-hole, universal-fit layout may still require checking hole spacing and alignment before installation.
  • It is made from black polymer plastic, which keeps it simple and functional but may not match every stock finish or material.
  • The tapered design offers both positive and negative adjustment ranges, but the exact result depends on the stock and how much adjustment is needed.
