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.

Best BCG on the market for the money !!!
Have run 600 + rounds not one misfire. Also using tulammo steel case cheep stuff. Tore the carrier down to clean it !!!!! It is slicker than my nickel boron coated ones. Only part carbon stuck to was the firing pin.

Great bcg
The carrier group is great. Barely noticeable tooling marks on one spot that you couldn't tell unless puposely looking, and one super tiny bur that knocked off with a cotton ball.

5 star quality/functionality, 2 star cost.
I am a gunsmith, who specializes in the AR platform. I had a few to many shipping issues with a major player in the BCG buisness, so I decided to shop around. I ordered a fail zero, and a spikes tactical BCG to be abused in testing with this BCG. The fail zero had problems after 4 thousand rounds. It lost its np3 coating and started sticking durring normal use the spikes tactical nickle boron BCG performed exceptionally well up to 9.5k rounds with only using the forward assist on 3 occasions. The BCG I ordered from this site went to 10k rounds, no hiccups at all. And actually felt smoother than the spikes after thoroughly cleaning both. I decided to go with this BCG in all my builds not only because of the cost, but the quality is actually as good, if not better than the $230.00 spikes BCG. This one also has an angled cam for feeding and extracting rounds no matter how dirty the M-4 feed ramps get. I am not one to usually write a reply, but this is a quality product...

bcg for .300 blk
Shipping was fast. Bolt arrived just as advertised. Good staking on key. Quality assembly, machining was smooth and flawless. Zero burrs for gas rings to snag. Finish was excellent also. Operation in 16" .300 blk was very smooth due to finish and bolt lug design. can't go wrong with this bcg for quality builds. I have used quite a few parts and complete uppers from SAA, zero issues with everything I've tried.
