Heighth Defense

Heighth Defense manufactures specialized grip modules and tactical components for the Springfield Echelon, engineered to convert a full-size pistol into a compact personal defensive weapon (PDW) or pistol caliber carbine (PCC). Everything is designed, manufactured, and assembled in the USA.

The HGM724 is the first PDW grip module purpose-built for the Springfield Echelon. It's engineered for shooters who move differently—compact enough for everyday carry in a bag, capable enough for immediate deployment.

Key Features: - Monolithic shrouds with full 3-side M-Lok coverage for lights, lasers, and slings - A.I.M.R (Auto Indexing Mag Release) places your finger exactly where it needs to be for faster reloads - Ambidextrous gas pedals for weak-side shooting and aggressive transitions - Rear shroud with integrated M-Lok slots for red dots and micro sights while preserving iron sight use - Fast, intuitive charging handle - D-shaped rear mount drops the stock rail low, keeping sight over bore tight and minimizing optic adjustments

The HGM825 is a compact variant priced at $360, also qualifying for the $15 stock bundle discount.

The HGM724 is designed for shooters running the Echelon as a bag gun—minimal footprint, maximum capability. It's engineered for real-world defense scenarios, not just range day. The design supports full-size control and optics-ready configurations while staying compact enough for discreet carry.

• •Springfield Echelon Compatibility: The HGM724 works with full-size Springfield Echelon models with threaded or non-threaded barrels. Aftermarket ported barrels are not supported.

• •Suppressor Support: Smaller diameter suppressors (1.05" range) will direct thread. Most standard 1.25-1.5" diameter suppressors require a 1" barrel extension for compatibility.

• •Optic Mounting: Red dot installation requires either a 5-slot Picatinny rail section or Heighth's SOB M-Lok to Acro sight mounts. More red dot footprints are in development.

1. A Springfield Armory Echelon (full-size model) 2. A 3-slot Picatinny rail section (for stock/brace attachment) 3. Optional: 5-slot rail section or SOB mount for red dots 4. Optional: Weapon light, compensator, or other M-Lok accessories

"This grip module will turn your Echelon into a PDW / PCC. Simply install your COG, mag release, slide and barrel and BOOM...instant upgrade."
