Material, Construction, and Weight

The Hogue 13103 is molded from a durable, impact-resistant polymer:

• Material: Polymer (textured)

• Color: Flat Dark Earth (FDE)

• Finish/texture: Cobblestone™ non-slip stippling pattern hogueinc.com+2Hinterland Outfitters+2

Internal and weight characteristics:

• Interior: Hollow core to reduce mass while retaining structural strength. Optics Agent+2customgunsolutions.com+2

• Approximate weight: About 1.6 oz, frequently described by vendors as the lightest AR pistol grip in its class. pelcheroutdoors.com+2Battle Born Armory+2

The hollow interior and polymer construction support long-term durability for duty, training, and recreational use while keeping rifle weight and rear-end balance in check.

Ergonomics and 15° Vertical Angle

The defining ergonomic feature of the 13103 is its 15° vertical grip angle:

• Grip angle: 15° (more vertical than standard A2 grips) pelcheroutdoors.com+2Optics Agent+2

• Intended stance: Designed for close-quarter and squared-off shooting positions, where the shooter’s shoulders are more square to the target and elbows are kept closer to the body. gunsmithfirearms.com+2Cheaper Than Dirt+2

This geometry can reduce wrist bend compared to more rearward-angled grips when running shorter stocks, collapsible stocks in a collapsed position, or when shooting from a modern, heads-up posture.

Cobblestone™ Texture and No-Finger-Groove Profile

The Flat Dark Earth 13103 grip uses Hogue’s Cobblestone™ surface and a clean, groove-free profile:

• Texture:

  • Cobblestone™ stippling – an efficient, non-slip, non-irritating pattern.

  • Designed to provide traction in wet, sweaty, or gloved conditions without being overly abrasive. pelcheroutdoors.com+2gunsmithfirearms.com+2

• Profile:

  • No finger grooves (as specified in several listings for this 15° vertical series).

  • Straight front strap accommodates a wider range of hand sizes and glove thicknesses without forcing the hand into predefined positions. Battle Born Armory+2gunsmithfirearms.com+2

• Recessed thumb/trigger dish:

  • A recessed dish surface behind the trigger heightens comfort and creates a smooth transition for the trigger finger from the grip to the trigger. gunsmithfirearms.com+2Cheaper Than Dirt+2

These features aim to deliver consistent control and comfort over extended firing sessions.

Design Features and Functional Characteristics

Core functional points drawn from manufacturer and distributor specifications:

Installation and Compatibility Notes

The Hogue Vertical Grip 13103 is intended for straightforward installation:

• Interface: Standard AR-15/M16 grip boss and screw arrangement.

• Installation steps (high-level):

  1. Safely clear the firearm.

  2. Remove the existing grip, capturing the selector detent spring.

  3. Position the Hogue 13103 grip, ensuring the detent spring is aligned.

  4. Reinstall and tighten the grip screw. hogueinc.com+2hogueinc.com+2

Hogue and resellers describe installation as easy and typically not requiring specialized gunsmithing tools, beyond a suitable driver for the grip screw.

The grip is not compatible with cargo-management systems or internal tool kits designed for grips with dedicated storage cavities, as this model uses a simple hollow interior without those accessory interfaces. hogueinc.com+1
