PTS EPG M4 Grip for M4/M16 GBB — Black

The EPG (Enhanced Polymer Grip) by PTS is a pistol grip for M4/M16 GBB receivers designed for airsoft, made from Dupont™ Zytel reinforced polymer. Dimensions are 76 x 32 x 108 mm and the angle follows the standard M4 geometry, preserved to ensure compatibility with conventional lower receivers.

The 360° texturing covers the entire contact surface but is distributed across strategic panels: the main grip zones are aggressive enough to hold under wet conditions or with gloves, while the lateral support areas are smoother to reduce fatigue during extended use. The beavertail extension naturally pushes the hand upward toward the receiver without any conscious effort from the shooter — this reduces the perceived torque during the blowback cycle. The bottom cap is removable and provides an internal compartment compatible with CR123 batteries, tools or spare parts — a feature exclusive to the GBB version, not available on AEG versions.

Key features

• Standard M4 angle with an optimised profile: fits existing lower receivers without modification and improves grip over the stock version.
• Integrated beavertail that guides the hand into a high position, increasing control during blowback without requiring deliberate adjustment.
• 360° texturing modulated by zone: secure hold where needed, comfortable support where the hand must not slip but should not chafe either.
• Internal compartment accessible from the bottom cap for CR123 batteries, small tools or spares — specific to the GBB version.
• Dupont™ Zytel reinforced polymer: lightweight and impact-resistant, retains its shape even after intensive airsoft use.
