AR-15 Pistol Buffer Tube Assembly Kit - Black

$ 32.49

Ground Zero PrecisionIf you're ready to try a short barreled upper on an "Other" AR-15 lower without any hassle a pistol buffer tube is a great way to go. This tube is precision machined on the latest CNC machinery from a 7075-T6 billet aerospace aluminum blank and finished with rugged matte black Mil-Spec Type III Class II anodizing. Throughout the manufacturing process tolerances are very tightly controlled so that the end product is a perfect fit with your receiver leaving zero gap between components while allowing zero play or wobble.

Our AR-15 Pistol Buffer Tube features a comfortable foam pad made from NPVC, also known as NBR or Nitrile. We chose this foam product for our pistol buffer tubes because of its resistance to oils / solvents, abrasion resistance and high tensile strength. NVPC is a very stable organic compound where the functional unit is a Carbon atom bonded to a Nitrogen atom with a triple bond. Typically the main causes of rubber break down are ozone and UV light. Our NPVC foam utilizes anti-degradants in its formulation to improve the resistance to the effects of ozone and UV light. These NPVC foam sleeves have great resistance against compression set (memory) when within a temperature range of of -20F to +220F.
