Leapers utg hard coat recoil buffer - UTG Pro Hard Coat Recoil Buffer for AR15 Carbine

Basic carbine buffer, what more can I say? Looks similar to others such as the Guntec, polymer pad seems to be a different durometer (a touch softer). Weights inside move just a touch more than the Guntec but not noticeable when in use. Buffers are pretty much all the same, might as well get the least expensive.
