Buy an HGM724 and get $15 off a stock!

The first PDW grip module built from the ground up for the Springfield Echelon.
 
Your Echelon is already one of the best striker-fired pistols on the market.  The HGM724 is what happens when you stop treating it like one.

Your Echelon's COG drops directly into the HGM724 with no modifications and no gunsmithing required.  What comes out the other side is a compact, fully configurable PDW platform that folds to 12 inches.  Run lights, lasers, a sling or a suppressor up to 1.05" in diameter.

    • KEY FEATURES

      HGM724

      • 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.
      • Dual Monolithic M-Lok Shrouds: Front and rear shrouds are manufactured as a monolithic unit.  The front shroud is reinforced with a stainless steel inner shroud for added durability where it matters.  M-Lok slots on the top and sides give you full accessory flexibility without adding bulk.  Run a light, laser, a sling mount or nothing at all.
      • 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 grip 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.
      • Precision Machined 7075 Aluminum Charging Handle (Included): Mil-Spec Type III hardcoat anodized.  The same allow used in aircraft structural components.  Included with every HGM724.
      • PA11 Nylon Construction: High-strength, impact resistant and dimensionally stable.

      The Perfect PDW

      For context I own a 320 Flux Raider and now the HGM. This chassis system is phenomenal. It is lightweight and compact which to me makes it perfect for bag carry. The built in handstop is unique and extremely useful when holding and firing (my hands are larger than average) the weapon. I also think the Echelon is one of the best striker fired guns on the market for the money so being able to transfer this over to a pdw and still carry the echelon itself makes it convenient for compatibility

      My new go to home defense PDW!

      This chassis is solid as a rock and shoots like a dream. I have used another system for glocks previously and the HGM724 blows it out of the water. The customer support is also top notch, no question goes unanswered.
