Let’s Talk About Luth-AR Mag Catch/Buttstock Plunger Spring
Every AR build, whether it’s a dedicated precision rifle or a lightweight carbine, depends on reliable small parts. The Luth-AR Mag Catch/Buttstock Plunger Spring is a seemingly insignificant component that plays a crucial role in the AR-15 platform’s functionality. I’ve spent countless hours building and tweaking ARs, and a faulty or out-of-spec spring can quickly turn a dream build into a frustrating jam-o-matic.
This particular spring is manufactured by Luth-AR, a company known for producing quality AR components. I wanted to get my hands on this because my old buffer tube on a build was beginning to not properly spring back when I removed my adjustable buttstock. This product seemed like a quick and cheap solution to potentially resolve my issue.
Upon receiving the Luth-AR Mag Catch/Buttstock Plunger Spring, I was initially surprised by its size. It’s tiny, but it has a critical role. The spring felt sturdy, and the steel seemed to be of decent quality.
I’ve used similar springs from Brownells and CMMG in the past. The Luth-AR spring appears very similar to those. I picked the Luth-AR spring this time because the price was great and Luth-AR has a great reputation.
My first impression was positive. The spring seemed well-made. It was a little anticlimactic because there’s not much to get excited about with a spring, but I was hopeful that it would solve my current problem.
Real-World Testing: Putting Luth-AR Mag Catch/Buttstock Plunger Spring to the Test
First Use Experience
I tested the Luth-AR Mag Catch/Buttstock Plunger Spring on my primary AR-15, a 5.56/.223 build that I use for range practice and occasional coyote hunting.

There were no surprises after the first use, thankfully. The Luth-AR Mag Catch/Buttstock Plunger Spring performed exactly as expected. It did solve my issue.

There are no signs of wear and tear on the spring, despite regular use and magazine changes. I have not seen any degradation of the spring’s strength. The product continues to perform as well as it did when initially installed.
