The JP Enterprises Gen 2 Silent Captured Recoil Buffer Spring Assembly for AR-15 is a drop-in upgrade that transforms how your rifle cycles. If you've ever winced at the harsh metallic noise of a standard buffer spring rattling back and forth—that "spoon over a cheese grater" sound—this system addresses it head-on with a carefully engineered captured-spring design that runs quieter and smoother right out of the box, with no permanent modifications to your receiver or tube.
What sets the Gen 2 apart is its dual approach to damping: a custom-ground buffer spring paired with the JP LMOS buffer work together to reduce friction and vibration across the entire cycle. The aluminum guide rod keeps overall weight down, and the assembly ships with three stainless steel weights that let you dial in the right amount of buffering mass for your specific rifle. Want more recoil control? Swap in a heavier weight. Running a tight cycle? Go lighter. That tuning flexibility matters, especially on rifles without an adjustable gas block, where the buffer system is your primary tuning tool.
The Gen 2 fits both carbine-length (M4-style) and rifle-length buffer tubes thanks to an included spacer, so whether you're running a collapsible stock or a fixed A2-style setup, installation is straightforward. The standard weight configuration tips the scales at approximately 3.0 ounces. If you want even finer control, JP offers optional Auxiliary Spring Rate Kits for additional tuning—a simple disassembly and swap of the spring lets you optimize performance for your exact setup. The interchangeable buffer design also means you can convert between AR-15 and AR-10 platforms if your collection grows.
| Product | JP Enterprises Gen 2 Silent Captured Recoil Buffer Spring Assembly |
| Platform | AR-15 |
| Buffer Tube Compatibility | M4-style carbine and rifle-length tubes (with included spacer) |
| Guide Rod Material | Aluminum |
| Weights Included | Three stainless steel weights |
| Standard Weight Assembly | Approximately 3.0 ounces |
| Buffer Tube Compatibility | Interchangeable with AR-10 buffers |
Yes. The Gen 2 comes with a spacer that allows installation in both carbine-length (collapsible M4-style) and rifle-length (fixed A2-style) buffer tubes.
The three included stainless steel weights let you adjust recoil damping on the assembly itself. For even finer tuning, JP offers optional Auxiliary Spring Rate Kits that allow you to swap the spring for different rates—particularly useful if your rifle doesn't have an adjustable gas block.
It's a true drop-in. The captured-spring design requires no permanent modifications to your receiver or buffer tube—simply install it like a standard buffer assembly.
The buffers are interchangeable between AR-15 and AR-10 platforms, so conversion between platforms is possible, though this product is configured for AR-15.
