PTS Enhanced Polymer Stock (EPS) Fixed Stock — Black

The PTS Enhanced Polymer Stock (EPS) is a fixed stock for airsoft built from DuPont™ Zytel® reinforced polymer, compatible with nearly all AEG and GBBR buffer tubes on the market. Overall dimensions of 205x135x63 mm give a compact profile without giving up internal storage.

The two side compartments, each with a usable space of 139x31 mm, are designed to fit 2/3A butterfly NiMH packs or LiPo packs, keeping weight centred on the rifle. They can also take AA, AAA or CR123A batteries and small accessories. The rear section of the stock accepts a 9.6 V NiMH minibattery or a LiPo of equivalent size, providing a second power option when you want to keep the side profile clear. The choice between the two compartments depends on battery type and buffer tube configuration — a trade-off between capacity and bulk worth considering before buying.

The removable rubber butt pad improves shoulder contact and absorbs recoil from the replica. The fixed side panels, beyond their functional role, create a consistent, non-slip cheek weld: a uniform contact surface that helps you return to the same shooting position every time. Sling attachment points are ambidextrous: both sides feature QD sockets for quick-detach slings, a loop channel for ring-style slings, and a front slot at the heel, covering most carry configurations without additional adapters.
