    • KEY FEATURES

      HGM825

      • A.I.M.R. (Auto Indexing Mag Release): Push the front mag release and pull down.  As the mag drops, your index finger naturally ends up at the bullet end of the magazine.  That is your index point.  It is the same position used to guide your fresh magazine into the magwell.  The A.I.M.R. puts your finger there automatically so the next mag goes in faster and more consistently, without having to think about it.
      • Shroudless Design - Full Platform compatibility: No front shroud means the HGM825 accommodates the full Echelon Lineup.  Run the 4.0" or 4.5" barrel in standard, threaded, comped, ported or suppressed configurations.  Maximum suppressor diameter is 1.35" without a barrel extension.
      • Direct Top-Rail Optic Mount: Mount your optic directly to the module, lower than standard risers.  Less height over bore means less compensation at close distances and a more natural point of aim.
      • Ambidextrous Gas Pedals: Built into both sides of the module.  Not an add-on.  Not optional.  They give your support hand a consistent index point under recoil so your grip stays locked in.
      • Aggressive Straight Jacket Grip Texture: Not decorative.  Engineered to maintain purchase under stress, in the rain and with gloves.  Works with the gas pedals to create a four-point grip that does not move.
      • PA11 Nylon Construction: High-strength, impact-resistant and dimensionally stable.
      • Precision Machined 7075 Aluminum Charging Handle (Included): Type III hardcoat anodized.  The same alloy used in aircraft structural components.  Included with every HGM825.

      Flux Who?

      This thing is absolutely dope! I've got a 300blk PDW and a Stribog SP9A3S. This thing is easily my favorite of the 3. From concealability to deployment and even comfort. Love this thing. Fits my OCL Lithium9 like a glove and vanishes into a backpack like it's a Mac Book Air. It's just as light as one too!

      This is so much fun!

      We had a spare Echelon as my wife had bought a comp version a few months back and this new chassis completely transformed it. This will probably be my new home defense gun as it is so good out to 20 yards. Keeping on target for follow up shots is effortless and so much lighter than our Ruger PCC. I highly recommend!
