Doublestar Corp. OOPS! Replacement Kit – AR-15 Detent & Spring Set

The Doublestar Corp. OOPS! Replacement Kit contains the small but critical detents and springs that inevitably launch themselves across the room during AR-15 assembly or maintenance. This kit replaces lost or damaged bolt catch detents, takedown pin detents, pivot pin detents, selector detents, and their associated springs—the parts most commonly lost during build or repair work.

Manufactured from quality steel and stainless steel, these replacement components meet mil-spec dimensions for proper fit and function in standard AR-15 lower receivers. This is a drop-in replacement requiring no gunsmithing, though a punch set and careful technique are recommended to avoid repeating the problem that made you need this kit. Keep a spare set in your workbench—you'll use it eventually.
