LANTAC E-BCG� Gen2 DI Side Charger Enhanced Bolt Carrier Group for .223/5.56 Caliber. - This bolt carrier group will not work in standard AR-15 upper receivers. It must be used with a side charging upper receiver. For guaranteed fit we recommend our LA-N15 Raven Side Charging Billet Upper Receiver. - M16 Full Auto Style for increased mass and lock time. - Our new BCG is precision machined from 8620 Steel with a shot peened bolt manufactured from Carpenter 158 or 9310 and Magnetically Particle Inspected. - The entire carrier assembly is NiB Electroless Nickel Boron coated with the patented advanced UCT EXO process unlike standard NiB coatings. - This offers extreme lubricity with a friction coefficient of .02 and surface hardness of 82-85 Rockwell C. - The carriers patented and patent pending design features unique shrouded and forward facing gas ports that have also been re sized so that gas is vented differently to a standard carrier. - This results in a system that runs flatter with a smoother energy pulse. - In addition the system also runs cooler and cleaner there is also less pressurization of the upper receiver when running a suppressed barrel. - The flared boss at the tail of the carrier enhances the BCG's lock position within the upper and makes it more consistent resulting in an accuracy improvement. - All critical dimensions are hard turned / ground after heat treat and the gas key has been hard chrome lined for the best possible wear resistance. - All E-BCG's� feature the LANTAC CP-R360 patent pending domed head cam pin that is machined from 17-4PH Stainless Steel and hardened to H900 condition (45RC approx). - The ultra smooth head reduces wear within the upper receiver. - The BCG's 11.7oz weight (Excluding Handle) helps to increase lock time and smoother operation. - Gas keys are properly staked at four points and only grade 8 fasteners are used in assembly. - The E-BCG's� forward porting and unique shape assist in reducing pressurization inside the up…
