Building or repairing an AR-15 means sourcing quality parts that work reliably without breaking the budget. The TPS AR-15 Stainless Steel Bolt Catch Assembly is a straightforward, cost-effective replacement or upgrade for your platform. This assembly handles the job of capturing and holding your bolt carrier group in the open position when your magazine is empty—a critical function in both tactical shooting and hunting applications. Stainless steel construction resists corrosion and wear, a practical choice for shooters who run their rifles in varied conditions or don't obsess over cosmetics.
Whether you're doing a complete lower receiver build from a 80% or finished receiver, or simply need to replace a worn catch on an existing rifle, this assembly includes everything you need in one package. That means fewer trips to the parts bin and less chance of losing small components during assembly. TPS Arms keeps the design straightforward and proven—no unnecessary complexity, just the parts that matter.
Fit and function are what count in a working gun, and stainless hardware has earned its reputation in the field. If you're assembling an AR or refreshing a rifle that sees real use, this bolt catch assembly is solid, practical, and ready to go to work.
| Brand | TPS Arms |
| Product Type | Bolt Catch Assembly |
| Platform | AR-15 |
| Material | Stainless Steel |
| Included Components | Bolt Catch, Buffer, Roll Pin, Spring |
The assembly includes the bolt catch itself, a buffer, a roll pin, and a spring—everything needed to install hold-open function on your AR-15 lower receiver.
This is a standard AR-15 bolt catch assembly designed for drop-in installation on AR-15 lower receivers. If you have a standard AR-15 platform, it will fit.
Stainless steel resists rust and corrosion better than standard steel, making it a practical choice if your rifle will see moisture, outdoor use, or extended storage. It's also harder and more wear-resistant over time.
Yes. If you're assembling a lower receiver from scratch or from an 80% receiver, this assembly provides the bolt catch function you need as part of your complete build.
