PTS Enhanced Polymer Stock Compact (EPS-C) — Black

The PTS Enhanced Polymer Stock Compact, known as the EPS-C, is an airsoft stock designed for standard airsoft buffer tubes. Measuring 175 x 40 x 130 mm and weighing 242 g, it is one of the slimmest and lightest stocks available for M4/AR-style platforms, built for shooters who want to minimise lateral bulk without giving up a solid cheek weld and shoulder contact.

The extremely slim profile is made possible by the use of DuPont Zytel high-performance reinforced polymer, a material that combines structural rigidity with weight savings. The length-of-pull adjustment lever is deliberately slim: it operates with a closed-fist method, pressing on the side opposite the palm. This geometry reduces the risk of accidental release during movement, aided by a protective rib integrated into the lever itself. It is worth noting that the reduced profile means the lever travel is shorter than on bulk stocks: shooters wearing thick gloves may find the action less immediate compared to a wider lever.

The sling attachment system is ambidextrous: the metal cup QD sling mount can be removed and reinstalled on either side of the stock without tools, adapting to the user's preference or vest configuration. A loop-type sling channel is also present. The angled rubber pad keeps the stock planted on the shoulder without snagging during target transitions. The lever also drops down at the rear to allow quick removal of the stock from the buffer tube, useful for accessing LiPo batteries stored inside the tube itself.

Key features

• Profile width of 40 mm: reduces lateral bulk and does not interfere with body armour or plate carriers
• Removable and repositionable metal QD mount on either side without tools, allowing sling attachment point to be changed at any time
• Adjustment lever with anti-release rib: the closed-fist method makes operation intuitive while guarding against accidental opening
• Quick removal from the buffer tube in a single motion, designed for tool-free LiPo battery access
• Angled rubber pad that keeps the stock stable on the shoulder without catching during movement
• Compatible with standard airsoft buffer tubes; weight of 242 g
