APS O-Rings for Magazine Base (AC011)
The APS O-Rings for Magazine Base, code AC011, are genuine replacement seals for the base of APS gas and CO2 pistol magazines. The O-ring at the magazine base is what keeps the seal tight where the base or cap closes, and over time it can flatten, nick or harden, leading to slow leaks and lost power. Fitting a fresh O-ring is a quick, cheap way to bring a leaking magazine back to life.
APS is a long-established airsoft manufacturer known for its gas pistols and CO2 replicas. Keeping a few spare genuine O-rings in your kit is good practice for any APS pistol owner, and this pack suits anyone maintaining their own magazines.
What you get
The product photo shows five O-rings together with a small additional item. Check the images and listing for the full contents.
Fitting
Remove the magazine base or cap as described in your magazine’s manual, after first making sure the magazine is completely empty of gas. Ease the old O-ring out with a non-metallic tool to avoid scratching the seat, clean the groove, then lightly lubricate the new O-ring with silicone oil and seat it evenly. Refit the base and test the magazine for leaks before game day.
