PWS Ratchet Lock Castle Nut & Endplate Set
The PWS Ratchet Lock Castle Nut & Endplate Set provides a secure alternative to a traditional staked castle nut on compatible AR-platform receiver extensions. Its ratcheting lock system allows the castle nut to engage positively against the endplate while still allowing easier future removal compared with a permanently staked setup.
The endplate also incorporates a QD sling mounting point, adding rear sling attachment capability without requiring a separate adapter. The kit works with both mil-spec and commercial receiver extensions, making it a versatile upgrade for a wide range of AR-15 and large-frame AR configurations.
