Validated in extreme military testing environments.
Trusted by 600+ law enforcement agencies nationwide.
At the heart of every reliable AR-15 is the Bolt Carrier Group. It is the engine that keeps the Rifle running under pressure. The SIONICS NP3 Coated Bolt Carrier Group was engineered for shooters who demand absolute reliability. Featuring a Nickel-Teflon NP3 coating, this
BCG runs smoother, cleans easier, and resists corrosion better than traditional finishes.
Today the SIONICS NP3 BCG is trusted by over 600 Law Enforcement Agencies across the country in their duty rifles.
While SIONICS did not pursue the rifle contract associated with those programs, the performance of NP3 coating helped demonstrate the advantages of this technology under severe testing conditions.
Proven Where It Matters Most
The NP3 coating used on the SIONICS Bolt Carrier Group has been validated in demanding military evaluation environments, where components are subjected to:
Sustained High Round Counts
Harsh Environmental Exposure
Limited Maintenance Conditions
Salt Exposure
These are the same types of environments where reliability is critical and failure is not an option.
Every BCG Is Tested Every SIONICS Bolt Carrier Group is test fired by SIONICS
prior to shipping to verify function and reliability.
Both the Carrier and Bolt components receive NP3 treatment, reducing friction and minimizing carbon buildup for easier cleaning and smoother cycling.
Properly Staking prevents loosening and ensures parts stay in place, working in conjunction with OCKS fasteners on BCG
The gas key is secured using Optimized Carrier Key Screws (OCKS) and properly staked to prevent loosening under heavy use.
