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.

Works great, I have to run a 3.8 oz buffer to slow it down to cycle correctly on a mid length carbine and full 20” rifle.

Enhanced Bolt Carrier Group
I haven't had a chance to install the BCG yet but I'm
sure sure it will function great. I've used many products sold by Surplus Ammo and all were top quality with no issues. -

Enhanced BCG
This is an excellent idea of instead of squared off lugs they are streamlined to facilitate easier entry to the feed ramp/barrel. I have bought 3 BCG's from Surplus Ammo and all of them have been excellent!

Good BCG
This is the 2nd enhanced BCG I purchased from surplus ammo and they both function flawlessly. Great price fast shipping. I only gave it 4 stars because the staking on the gas key is not as good as the first one i purchased but I'm sure will definitely hold up to the abuse.

Great bcg. The gas key was not staked correctly tho. Cost me $20 more at the gunsmith to have this corrected.
