Anderson Manufacturing OOPS Spare Kit Review

Let’s Talk About Anderson Manufacturing OOPS Spare Kit

The Anderson Manufacturing OOPS Spare Kit is a must-have for any AR-15 owner, builder, or tinkerer. Manufactured by Anderson Manufacturing, this inexpensive kit provides a comprehensive assortment of those easily lost or damaged small parts that are critical to the AR-15 platform. I was drawn to this kit after one too many frustrating experiences of launching a detent pin into the unknown abyss of my workshop.

Building AR-15s is a rewarding hobby, but it inevitably leads to the dreaded “oops” moments. Springs and detents have a knack for becoming airborne at the most inopportune times. The Anderson Manufacturing OOPS Spare Kit seemed like a small investment to avoid project delays and potential trips to the local gun store.

Upon receiving the kit, I was immediately impressed by the organization and completeness of the parts. Everything was neatly packaged and clearly labeled. The components appeared to be of good quality, especially considering the low price point. Compared to buying individual replacement parts, this kit seemed like a much more efficient and cost-effective solution. My initial reaction was one of relief and anticipation, knowing that I could tackle future builds and repairs with greater confidence and less anxiety.

Real-World Testing: Putting Anderson Manufacturing OOPS Spare Kit to the Test

First Use Experience

My first opportunity to utilize the Anderson Manufacturing OOPS Spare Kit came during a lower receiver assembly. I was installing the bolt catch when, predictably, the detent and spring decided to take flight. Fortunately, the kit was within reach, and I was able to quickly retrieve a replacement detent and spring.

The replacement parts fit perfectly, and the assembly continued without a hitch. Using the Anderson Manufacturing OOPS Spare Kit in this situation saved me considerable time and frustration. I was able to finish the assembly that day, without having to wait for replacement parts to be shipped.

Extended Use & Reliability

After several months of use and multiple AR-15 builds, the Anderson Manufacturing OOPS Spare Kit continues to be an invaluable asset. The springs and detents have held up well. There are no signs of wear and tear.

Maintaining the kit is straightforward; simply keeping it organized and readily accessible is all that’s required. The availability of these spare parts has significantly reduced the stress associated with AR-15 maintenance and customization. It definitely outperforms my previous “hope for the best” approach to small parts management.

Breaking Down the Features of Anderson Manufacturing OOPS Spare Kit

Specifications

The Anderson Manufacturing OOPS Spare Kit includes the following parts:

• Bolt Catch Detent: A small, but essential part that keeps the bolt catch in place.
• Bolt Catch Pin 3/32? x 1/2? Coiled Pin: Secures the bolt catch to the lower receiver.
• Bolt Catch Spring: Provides the tension needed for the bolt catch to function properly.
• Buffer Detent: Holds the buffer tube in place.
• Buffer Detent Spring: Keeps the buffer detent under tension.
• Disconnect Spring: Essential for the proper function of the trigger mechanism.
• Magazine Catch Spring for AR15: Provides the tension needed to securely hold the magazine.
• Safety Selector Detent for AR15: Keeps the safety selector in the selected position.
• Safety Selector Spring: Provides the tension needed for the safety selector detent.
• Take Down Pivot Pin Detent (2 needed per rifle): Keeps the takedown and pivot pins in place.
• Detent Take Down Spring (2 needed per rifle): Provides the tension needed for the takedown and pivot pin detents.
• Hammer Spring mil spec: Powers the hammer to strike the firing pin.
• 1/8 x 5/8 coiled Roll Pin for Trigger Guard: Secures the trigger guard to the lower receiver.
• Trigger and Hammer Pin for AR15 (2 needed per rifle): Attaches the trigger and hammer to the lower receiver.
• Trigger Spring single stage mil-spec: Provides the tension needed for the trigger to reset.

These specifications are vital for the proper functioning of an AR-15. A missing or damaged spring or detent can render the rifle inoperable. Having spares on hand ensures that repairs and builds can be completed without delay.

Performance & Functionality

The Anderson Manufacturing OOPS Spare Kit excels at its primary function: providing readily available replacement parts. The springs and detents are manufactured to mil-spec standards, ensuring compatibility and reliable performance. The kit is a lifesaver when a spring or detent is lost or damaged during a build or maintenance procedure.

The only improvement I would suggest is to include an extra takedown/pivot pin detent and spring to match the quantity used per rifle. The current kit only includes two of each, which is precisely the amount required for one rifle, leaving no spares for that specific component if it is lost.

Design & Ergonomics

The design of the Anderson Manufacturing OOPS Spare Kit is simple yet effective. The parts are clearly labeled, making it easy to identify and retrieve the desired component. The kit itself is compact and easy to store.

There is no learning curve associated with using this kit; if you are working on an AR-15, you already know what each part is for and where it goes. The parts themselves are small, but they are well-made and easy to handle with the right tools.

Durability & Maintenance

The springs and detents included in the Anderson Manufacturing OOPS Spare Kit are made from durable materials designed to withstand the rigors of AR-15 operation. With proper storage, the parts should last indefinitely. The kit requires virtually no maintenance; simply keep it organized and protected from moisture.

Accessories and Customization Options

The Anderson Manufacturing OOPS Spare Kit does not require any additional accessories or customization options. The kit is a self-contained solution for replacing lost or damaged small parts. Its compatibility with standard AR-15 components ensures that it can be used with any AR-15 build or maintenance project.
