Description

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 upper receiver that can be caused by short barrel rifles running suppressors. – However it should be noted that the E-BCG® is not a complete solution for this issue and all rifles are different. ‘Over Gassed’ guns will suffer to a larger extent from this problem. – This Side Charger version comes complate with our 440 Stainless Steel Knuled screw in handle. – Weight 11.7oz (Excluding Handle). – Forward Porting enlarged vents. – Balanced flared boss. – 8620 Carrier Heat Treated Hard Turned & Ground. – MPI Carpenter 158 or 9310 Bolt Shot Peened Hard Turned / Ground. – NiB UCT EXO Coating. – CP-R360 Domed Cam Pin – Mil-Spec Gas Rings – Mil-Spec Staked Gas Key – Grade 8 Hardened Fasteners – All Hard Chrome surfaces are to MIL-STD-171 1.2.2.2 – Shot Peening is conducted with S110 shot Established by Almen Gage A-2 strip .006 -.008 – Lifetime Warranty. – Patented. – Made in the USA.
