A stock built to work as hard as you do

The PTS EPS (Enhanced Polymer Stock) is one of the most practical fixed stocks in airsoft. Moulded from genuine Dupont Zytel polymer, it shrugs off the knocks, drops and grime of a full day on site while keeping a slim, purposeful profile on your M4 buffer tube.

Cheek weld and comfort that hold up round after round

Fixed side storage compartments give the EPS a broad, consistent cheek platform, so your eye returns to the same spot on every shot. The rubberised, removable butt-pad locks into the shoulder and cushions the sharp recoil pulse of Tokyo Marui Recoil rifles and gas blowback builds.

Serious battery storage

Each side compartment offers up to 139 x 31 mm of usable space. That is enough to hide 2/3A NiMH packs, LiPo batteries or AA, AAA and CR123 cells inside the stock, a real bonus on Next Gen Recoil rifles where battery room is always tight.

Fits your platform, slings your way

The EPS drops onto almost any standard 1.148in airsoft buffer tube across AEG and GBBR platforms. QD swivel sockets sit on both sides, backed by a loop pass-through channel and a front sling slot, so single or two-point ambidextrous slings fit straight out of the box. Choose Black or Dark Earth to finish your build. Need it fitted or paired with an upgrade? Our in-house airsoft techs in Kent can help, and you can browse more airsoft accessories to complete the rifle.

Frequently asked questions

Will this stock fit my AEG or gas rifle?

Yes, the EPS is designed to slide onto almost any standard airsoft M4 buffer tube of 1.148in diameter, covering the vast majority of AEG and gas blowback (GBBR) platforms including Tokyo Marui Recoil, VFC, G&G and Krytac.

How much battery space is inside?

A lot. Each fixed side compartment gives up to 139 x 31 mm of room, enough for 2/3A butterfly NiMH packs, LiPo batteries or AA, AAA and CR123 cells. It is a genuine help on tightly packed recoil rifles.

What is the stock made from?

It is moulded from genuine Dupont Zytel, the same reinforced polymer PTS uses across its high-end furniture. It resists knocks, abrasion and field abuse far better than cheap generic stocks.

Does it come with a sling mount?

Yes. There are QD swivel sockets on both sides, a pass-through channel for loop style slings and a front sling slot, so you can set up an ambidextrous single or two-point sling without extra parts.

What is the difference between Black and Dark Earth?

Only the colour. Both share identical construction, fitment and storage. Choose Black for classic builds or Dark Earth (FDE) to match tan furniture and multicam loadouts.
