NFM Elite Bolt Carrier Group

Newtown Firearms BCG

Newtown Firearms announced the company is now selling a drop in replacement for the direct impingement AR-15 bolt carrier group. The NFM Elite Bolt Carrier Group is fluted and comes in one of two different finishes.

Exterior fluting is said to reduce the weight of the BCG plus help prevent debris from gumming up the unit’s movement. Newtown Firearms is offering these units with one of two different standard finishes: Diamond-Like Carbon (DLC) and Physical Vapor Deposition (PVD). Both finishes are supposed to reduce friction and wear in the system.

According to the company, the new BCG offers:

  • Direct drop-in replacement
  • Fluted front to back for weight reduction / debris disbursement
  • Available in DLC or PVD coatings
  • 0.01 coefficient of friction
  • Hardness rated at 3000 Vickers
  • Withstands temperatures up to 1,100°F
  • Coating is 2-3 microns thick
  • Additional coating colors are available

The MSRP is $249.99.

    Unnecessary fluting is unnecessary.

    • BillC

      It’s fluted for your AR-15’s pleasure!

    • Jessi

      “Fluted front to back for weight reduction / debris disbursement.” Sounds necessary to someone who loves quality.

      • Grindstone50k

        I’d like to see that claim tested.

      • Joshua

        Lol no. Especially the debris part, you know since the bolt carrier is suspended inside the upper by the 4 small carrier rails.

        This “debris cuts” won’t do anything since that part of the carrier doesn’t touch anything.

          Americans are great at marketing… That much I have learned by reading gun-stuff online the last few years.

          Take Desert Tech. Undoubtably a great gun, but is is for all intent and purposes a rip-off of the DSR-1, which is hard to find any information on at all. I have seen the barrel change system, and it is pretty much the same. Marketing is key…

      • Thomas Gomez

        Quality has nothing to do with fluting, weight reduction and coating. For competition this is fine. In regards to this going on a fighting rifle…no thank you. No need to play with buffer springs, buffer weights etc….especially as you approach that 10,000 round mark where your gas port is going to be enlarged.

    There are ordering restrictions on the gold version requiring 500 headshots.

    Everyone’s being so hard on this, but we all know its just for guys that got bored with their last 15 “mods” and have some cash lying around that they don’t know what to do with.

    • Norm

      Like most mods, actually. 🙂

  • BillC

    A fool and his money.

    These carriers are absolutely stellar. I take my rifle seriously and want the best, most dependable parts I can run. I shoot 3 gun on a competitive level which should quantify my claim that these are hands down, the best carriers on the market. If you enjoy that nasty, gritty grinding sound and feel you get from your stock carrier, by all means, ignorance is bliss. Until you try one of these bad boys, and see the actual benefits for yourself, don’t knock it. While other guys and gals at the range pull out their fancy carbon scrapping tools, I wipe carbon off with a rag and keep rocking. On top of the functionality of the reduced friction, no carbon build up and flawless operation, the black dlc looks mean as hell.

      glowing endorsement of the product being “advertised”

      hmm… who can possibly put those clues together

    • Thomas Gomez

      So my Colt and BCM bolt Carrier groups are garbage? Hard to justify a product based on a “gritty grinding sound” and “looking meaner then hell”. Black DLC is cool though.

      And dear readers…you should never scrape carbon off a Bolt Carrier Group with a metallic object (or at least something that has a Rockwell hardness that exceeds the metal). Spray some Fireclean, CLP or MPro and give it a minute or two before wiping it down. Fireclean does wonders on carbon. Bolt carrier groups can run filthy as long as your gas rings, extractor and extractor spring have been replaced every 5000 or so rounds and there is some amount of lubrication.

  • Vitor Roma

    Is the 0.01 coefficient of friction valid for both finishes?

  • Marcus D.

    Coatings, sure, fluting, give me a break.

  • Shmoe

    I see a lot of complaints about the fluting. Is there anything wrong with lightening your BCG as long as adjust your buffer and spring accordingly? Where’s Andrew Touhy when you need him? Corpsman!

  • cs

    The name “Newtown Firearms” seems a little more than Ironic.

    • sauerquint

      If only they’d put a Confederate flag on it.

  • Bobing

    If you could just buy a lighter semi-auto or JP-style race competition BCG, why not just coat one of those profiles and save your company the machine time?
