DETAILS
DETAILS
- description
Gas capacity is the quiet limit on a blowback pistol. Towards the end of a magazine the reservoir is low, the pressure drops and the last few shots go nowhere. Extending the base gives the magazine more gas to work with, so the whole magazine shoots the same.
You also get four or five more rounds, but the gas is the real gain. The APEX profile is tighter and around 16 g lighter than the generation before it, with bevelled sides and cutouts that give your hand something to index against on a fast reload.
It arrives as a working kit rather than a part: the 180 mm high-tension spring, the long steel screw, the sealing gaskets and a WE/AA fill valve already fitted.

Good to know before you buy
Fitting means stripping the magazine base, which is the one job on a gas pistol where a slipped screwdriver costs you the whole magazine. Take your time and work over a tray.
Use the supplied spring rather than keeping the original. The extra length is what fills the new space, and the old spring will feed badly in it.
The gaskets are what stop it leaking. If the magazine hisses after assembly, take it apart and check them before you blame the valve.
It is cut to clear CTM magwells. If you run another brand of magwell, check the base will pass through before ordering.
Frequently asked questions
How much extra gas is that really?
Eight to twelve grams, which on most magazines is the difference between the last five shots being full power and being disappointing.
Will it fit a Glock magazine?
The listing covers Tokyo Marui and WE G-series magazines alongside the AAP-01. Check your own magazine against the plate before you commit.
Does the spring come with it?
Yes, a 180 mm high-tension spring, along with the screw and the gaskets.
Is the fill valve already in?
Yes, a WE/AA spec valve is pre-installed.
Will it clear my magwell?
It is designed around CTM’s own AAP-01 and Hi-Capa magwells. Other brands may sit differently.
Do the colours cost the same?
Yes, all seven are one price.
