LMT Enhanced Full-Auto M16 Bolt Carrier

The Lewis Machine and Tool AR-15 Enhanced bolt carrier is a full auto rated, M16 cut carrier designed for reliability in overgassed weapons.

If our standard bolt carrier is the infantryman of the gun industry, then our enhanced carrier is the delta operator. This carrier was designed to function effectively in full-auto, suppressed, and short barrel weapon systems, and it is made of materials far more durable than your standard fare. Quite simply, it’s the best possible upgrade for your rifle to increase reliability and functionality.

The LMT enhanced carrier offers the following:

  • Altered cam path for longer dwell time and more robust extraction
  • Modified gas hole improves gas flow across the bolt’s tail
  • Additional gas ports on right side and modified orientation to improve gas flowing through the ejection port, and not into your face
  • Relief grooves added to the top and bottom to channel debris and maintain fluid movement
  • Manganese Phosphate finish
  • 8620 carrier
  • Properly staked gas key
  • Hardened gas key screws
  • Made in the USA

    I run this carrier with a headspaced bolt on a 10.5″ barrel SBR.

    I’ve run the Sharp’s Reliabolt BCG, Lantac Enhanced, milspec through this gun to combat gas face indoors.

    Milspec- gas face, hard to clean
    Sharps- Gas face, easy to clean
    Lantac- Less gas face, easy ish to clean
    LMT- Least gas face, easy ish to clean.

    The LMT actually redirects the gas like they say. So for me, in my application it doesn’t hit me dead in my eye and disable me as fast as any other carrier has. It still will build up and slow me down as I usually I shoot with no eye protection so this is how I rate the product. The best carrier choice for gassy can suppressed SBR, one vote.

    It’s amazing. Pricey. Tight fit the first time you get your bolt in it. Smooth cycling. And it works just fine, no adjustments to gas block were needed when swapping this carrier in. Don’t mind the dwell time rumors.

    Paired with a BCM Bolt in a Criterion Core.
    She tight, but she slaps. Great product.

    Ordered this LMT Enhanced Carrier to further refine the gas tuning on a fussy mid-length I have. Fast shipping and great service from Rooftop Defense!

    Rooftop Defense wasted no time getting it out to me. As for the product it self, it’s a well made bolt carrier and it preforms as expected. You get what you pay for.

  5. Kyle (verified owner)

    I bought this for a future build but have yet to use it or even remove it from the package to be honest. However, LMT and this bolt have a good reputation so at the very least for my purposes it’s a great spare part at the moment.

    As always, the sweatshop got it to me lightning quick as part of a huge order that had a ton of tiny parts as well and it all arrived flawlessly.
