Building or maintaining multiple AR platforms means keeping spare parts on hand, and buffer retainers are one of those easy-to-lose consumables that always seem to disappear when you need them. The Luth-AR Buffer Retainer with Spring Manganese Phosphate 10-Pack solves that problem by giving you a full set of replacements without hunting down singles every time you swap uppers, service a rifle, or help a buddy with a build. Each retainer is precision-engineered to keep your buffer seated and under tension inside the buffer tube where it belongs—a small part with a big job in keeping your AR-15 cycling reliably.
What makes these worth stocking? Luth-AR finishes them in mil-spec manganese phosphate, the same coating you'll find on quality mil-spec parts. That finish resists corrosion and handles the wear from regular assembly and disassembly without chipping or flaking. Whether you're a gunsmith, a builder who's always tinkering, or just the friend everyone calls for AR wrenching, having a 10-pack means you'll never be caught short during a tear-down or build day.
The specs are straightforward: each retainer measures .247" in diameter and is finished to mil-spec standards. Installation is straightforward on any standard AR buffer tube. This is the kind of part that seems tiny until you're missing one—then it becomes mission-critical. Smart builders keep them in a kit or on the shelf next to springs and takedown pins.
| Diameter | .247" |
| Finish | Mil-Spec Manganese Phosphate |
| Quantity | 10 Pack |
| Application | AR-15 Buffer Tube |
The buffer retainer clips into your buffer tube and holds the buffer in place under spring tension. It prevents the buffer from shifting or falling out during assembly, disassembly, or when the gun is inverted.
Yes. These are standard .247" diameter retainers designed for AR-15 buffer tubes with the standard mil-spec dimensions. They work on any AR-platform rifle using a standard buffer tube.
If you build or maintain more than one AR, or if you frequently service your rifles, buffer retainers are small enough to lose and cheap enough to buy in bulk. A 10-pack means you'll have spares on hand and won't be hunting for one mid-build.
