Zooming way in on the photo, I think the bolt might be fluted similarly, but can't be 100% since I can only see what looks like a little bit of a lip. DSA is the first result for NTFE coating, so I have no idea what it is. From the color I'm guessing a nickel teflon?

Quote HistoryQuoted: Sand cut? Some KAC SR-25s have a sand cut BCG for better reliability in adverse environments. I'm not sure if it's found on the MK11 or M110 systems so I'll wait for a more knowledgable person to chime in. |

It's what KAC does on SR25 and SR16's.

Looks quite logical to me...
FALs have sand cuts on the English L1A1 rifles. |

The pattern of sand cuts are the same as the cuts used in the 1950s l1a1 rifle sand cuts on bolt carriers including m16/ar10 rifles have prior art that goes all the way back to the 50s, sand cuts and ice grooves are not a new invention in firearms including the m16 hence why we did not file a patent for this. |

I dig the sand cut, but give me a nitride or melonited one and youve got a sale.

Again, what is an NTFE finish? |

The DSArms NTFE(Nickel Teflon Extreme) Finish blends the fantastic properties of Nickel and Teflon to provide a finish with a higher lubricity, exceptional hardness and extreme corrosion resistance. DSArms NTFE finish has a lower friction coefficient than Nickel Boron and because the Teflon is impregnated into the Nickel it holds this low friction coefficient longer than a Nickel Boron Finish. DSArms NTFE also outperforms the best Nickel Boron Finishes in salt water corrosion testing. Nickel Boron in its best forms is rated to 96 hours in salt water corrosion testing; in comparison DSArms NTFE is rated to 220 hours!

Nickel Teflon was the magic word. Order placed.

Awesome. However, i don't think I'd need this here in Southeast Texas. Not much sand 
But, i don't really clean my rifles very often, so maybe this could help me go longer? Ha! |

How does this stack up against NP3?

Can I order just the carrier? Not the entire BCG.

At this time we are only offering the complete bolt carrier group assembly. As production allows in the future we may offer only the carrier but no specific time frame.
Thanks, Mike DSArms |

Id rather it come with a 158C bolt. Too many ways to screw up with 9310, always has me skeptical. I know when done right, it's great and certainly stronger. But, if rather have the tried and true bolt.
Maybe have an option for it? |

Lubricant has a slow to pool now due to the space created between the carrier and the receiver allowing for retention of lubrication and longer lubrication . |

http://www.dsarms.com/images/product/large/16061_1_.jpg I am guessing that the statement above is based on the 'filmy' look that the inside of the carrier appears to have? That is just the by product of the rinse from after the item is coated and is perfectly natural and normal. We have been using the same company for years for our various coatings and have never had an issue! Thanks, Mike DSArms |
