SAA AR-15/M16 Nickel Boron ENHANCED Bolt Carrier Group (BCG) - .223/5.56/300AAC

Product Description

SAA - AR15/M16 Nickel Boron ENHANCED Bolt Carrier Group (BCG)

A completely assembled, ready to install M16/M4 Bolt and Carrier System.  This BCG greatly improves the performance of your AR-15 and eliminates the need to apply oil or grease to treated parts for the life of the weapon.  Nickel Boron treated parts include: Carrier, Bolt.  Phosphate extractor, Key and screws, firing pin retaining pic (cotter pin) and Cam pin.

SAA ENHANCED Bolt:

WHY it is Superior to the original AR bolt - The SAA Enhanced Bolt has a camming action that moves the bolt past obstructions like carbon build-up within the barrel extension.  Using its rounded and tapered lugs (in contrast to the squared lugs of the original AR bolt design) to push past and then fully engage the barrel extension for complete strength and a secure lock-up.  The SAA Enhanced Bolt will virtually eliminate most AR carrier/bolt malfunctions as a result of its unique design.

Strength and Reliability - The SAA Enhanced AR15/M16 machined from S7 tool steel and tempered with a proprietary heat-treating process, significantly increasing strength when compared to mil spec Carpenter 158. S7 provides a 75% increase in tensile strength, and nearly 60% improvement in yield strength. 

Superior Corrosion Resistance - Every SAA Enhanced Bolt is coated with NP3®, an electroless nickel-based finish. This process co-deposits sub-micron particles of PTFE (polytetrafluoroethylene), commonly known as Teflon™, for self-lubricating corrosion resistance. 

MPI, and Shot-Peened Magnetic Particle Inspected and Shot Peened, the SAA Enhanced Bolt is guaranteed to perform under pressure.
