Genuine Vorsk VMP base seal

The base seal sits at the bottom of your Vorsk VMP magazine and seals the gas reservoir so it holds pressure. It is one of the most common wear items on any gas magazine, and a tired base seal is usually the reason a mag empties itself overnight or refuses to hold gas at all. This is the genuine Vorsk part, sized correctly for a proper airtight fit.

The most common leak fix

If your gas magazine has been left empty over a period of time, the seal may have dried out and shrunk. Rather than writing off the whole magazine, this low-cost spare is almost always the fix. It restores a positive seal so the reservoir holds pressure and your gun cycles with full recoil.

Quick and simple to fit

Simply knock the bottom retaining pins out, lubricate and change the seal, reinsert the pins and away you go. Keep it coated in silicone and always leave a small amount of gas in the mag when stored to make the seal last.

Fits VMP-1 and VMP-2

This seal suits Vorsk VMP-1 and VMP-2 gas magazines. Stock up on green gas at the same time, or book the magazine in with our Kent servicing team for a full refresh.

Frequently asked questions

What does the base seal do?

It seals the bottom of the gas reservoir inside your magazine, holding pressure so the mag charges and cycles the gun properly rather than leaking down.

Which magazines does it fit?

It is the correct base seal for Vorsk VMP-1 and VMP-2 series gas blowback magazines.

How do I fit it?

Knock out the retaining pins at the bottom of the magazine, remove and lubricate the new seal, fit it, then reinsert the pins. It is a quick, tool-light job.

Why does my magazine keep leaking?

If a gas magazine is left empty for a long time the base seal can dry out and shrink. Replacing it, and always leaving a little gas in the mag, prevents this.

How long does a base seal last?

It is a consumable part. Keeping it lubricated with silicone and never storing the magazine bone-dry will extend its life considerably.
