Odin Works Adjustable AR-15 Lite Buffer 2.1-4.2 oz Aluminum

The Odin Works Adjustable AR-15 Lite Buffer is a tunable carbine buffer that lets a single part cover what most AR-15 shooters want out of a buffer. Its lightweight aluminum body with a nylon endcap sits at the standard 3.25" carbine length, so it drops directly into any mil-spec AR-15 buffer tube as a true drop-in replacement.

Two set screws at the front of the buffer lock the weight stack in place so nothing shifts under recoil. The Lite kit ships with seven interchangeable weights - 3 aluminum, 3 stainless steel, and 1 tungsten - giving you an adjustable range of 2.1 oz to 4.2 oz of buffer weight. That spread is enough to dial in felt recoil, brass ejection timing, and overall reliability across suppressed hosts, adjustable gas blocks, short-barrel builds, and a wide variety of ammunition loads without having to buy multiple dedicated buffers.

Designed and built by Odin Works as part of their adjustable buffer family, the Lite version is the lighter-duty option aimed at AR-15 carbines running standard and lighter-recoil loads. The same standard carbine footprint also fits AR-10 and 9mm AR builds that use a mil-spec buffer tube.
