The Odin Works Adjustable AR 9mm Buffer (brand part number OSABS9MM) lets 9mm AR builders tune buffer weight to their exact bolt carrier group and recoil spring combination instead of swapping fixed-weight buffers to find the right cycling feel. Odin Works builds the buffer body from stainless steel and includes one aluminum weight, one stainless steel weight, and three tungsten weights, giving a total adjustable range from 5.4 ounces up to 7.4 ounces. That range covers most 9mm blowback builds, from a suppressed SBR looking for softer cycling to an unsuppressed carbine that needs extra mass to tame bolt bounce. Being able to mix and match weights means a shooter can dial in smoother, more reliable cycling without buying multiple buffers to experiment.
