Description
Specification

Get your stock back to full working order

Lost a stock cap on the skirmish field, or picked up a second-hand AEG that arrived without one? The Nuprol Delta Stock Cap is the genuine replacement for Nuprol’s M4 and AR variant stocks, letting you close up the battery compartment and get back on the game for the price of a coffee.

Broad Nuprol compatibility

This cap fits across the Nuprol Delta line, including the Pioneer Defender and Breacher, Enforcer, Nomad and Recon series. If you run one of these M4-style platforms, this is the part that keeps the rear of the stock sealed and rattle-free.

Protects what matters

The cap closes off the stock tube so your battery and wiring stay put and protected from grit, moisture and impacts during play. A missing cap risks a battery working loose mid-game, which is the last thing you want mid-push.

Spares and servicing

Sold individually so you only buy what you need. Find more parts in our airsoft accessories, or let our team handle it through our Kent airsoft repair service.

Product information reviewed by James Smith. Every gun is checked & serviced by our Rochester workshop before dispatch.

Frequently asked questions

Which guns does this cap fit?

It is designed for Nuprol Delta M4 and AR variant AEGs, including the Pioneer Defender and Breacher, Enforcer, Nomad and Recon series.

What does the stock cap do?

It closes off the battery compartment inside an M4-style stock, keeping your battery and wiring tidy and protected from dirt and knocks.

Is it sold on its own?

Yes, it is sold individually, so if you have lost or broken a single cap you only pay for the one part you need.

Will it fit other brands of M4 stock?

It is made to Nuprol's spec. It may suit some other M4-pattern stocks, but fit is only guaranteed on the listed Nuprol Delta models.

Do I need a UKARA defence to buy this part?

No. This is a replacement accessory, not a two-tone or realistic imitation firearm, so no UKARA defence or age check applies.
