DoubleStar AR-15 OOPS! Replacement Springs & Detents Kit
The DoubleStar Oops! Replacement Kit is an essential collection of small-but-critical AR-15 components that every builder, shooter, and range-goer should keep on hand — because losing a detent or spring at the wrong moment shouldn't end your day.
- Includes 18 commonly lost AR-15 pins, springs, and detents in one kit
- Four takedown detents and four takedown detent springs for quick repairs
- Two buffer detents and two buffer detent springs keep your build running
- Two firing pin retaining pins prevent costly field malfunctions
- Two extractor springs with bumper pads maintain reliable ejection performance
- Compact size fits in a range bag, backpack, or jacket pocket with ease
Who This Is For
The DoubleStar Oops! Kit is ideal for AR-15 owners who build, maintain, or frequently shoot their rifles — whether you're a home gunsmith prone to losing tiny parts during assembly, a competitive shooter who needs a field-ready repair kit, or a range enthusiast who wants peace of mind that a dropped detent won't sideline your session. It's equally valuable for anyone doing their first lower build who wants backup parts on standby.

Frequently Asked Questions
Which AR-15 builds or platforms is this kit compatible with?
The DoubleStar Oops! Kit is designed for standard AR-15 and M16-pattern rifles built to mil-spec dimensions. The detents, springs, and pins in this kit correspond to standard lower receiver components, making it compatible with the vast majority of AR-15 builds using mil-spec parts from any manufacturer.
Can I use this kit for a first-time AR-15 lower build?
Absolutely. In fact, this kit is a smart addition to any first-time lower build. Small parts like takedown detents and selector detents are notoriously easy to lose during assembly. Having extra pieces on hand means a fumbled detent won't stall your entire build or require a separate parts order before you can complete your rifle.
How should I store this kit to keep the parts organized?
Because the components are small, it's best to store the kit in a labeled zip-lock bag, a small parts organizer tray, or the original packaging. Keeping the kit in your range bag or gun case ensures the parts are available whenever you need them. Avoid loose storage in drawers where tiny springs and detents can easily be misplaced.
