Our Pepper and US Popper Targets are constructed of the same durable, 3/8" Thick, AR500 steel as our rifle targets. Made to withstand years of abuse. Heavy duty, fully welded steel bases feature an adjustable stop to tune how much force is required to neutralize the target. Bases are universal and work with either a US (28x8) or Pepper Popper 42x12). All of our Pepper poppers come standard with extra holes used to make them activate other moving or falling targets.
