The sleekest way to HPA your TM MWS.
We've massively redesigned this HPA adapter to sit completely inside the magwell (no more sticking out), with an elegant two part magazine catch, and an adjustable side shim system for stability across all metal Cyma MP5 mid caps in ALL MWS/Clone receivers.
Works excellently with the T1P HPA Dead Drop Grip.
Comes pre-fitted with valve, feed lips and gas router - you do not need to use any donor parts. No assembly is required.
SHIM ADJUSTMENT INSTRUCTIONS
If a CYMA MP5 magazine seems two wide, remove one of the two side wings, marked red on the image below, using a 1.5mm hex key. Some gentle filing of the shims can also be done to improve fitment in the case of CYMA MP5 mags that are stamped too wide.

If a straight MP5 magazine is not feeding or has too much vertical play, install the fitment block inside the magwell, shown in the image below

Product Information
We test each adapter in a Tokyo Marui / DE MWS before shipping.
This is also compatible with the Salvo Precision MCX Virtus.
The gas router for this adapter is made from injection moulded rubber, to the standard MWS spec and dimensions, meaning you can use a factory or aftermarket MWS router should you wish. TM MWS feed lips are also compatible with this adapter.
We utilise a very high flow valve. This has allowed us to build a far more reliable adapter that is capable of high FPS and sustained full auto.
A rear shim is included, which can be fitted to increase air seal (due to manufacturing tolerances between various brands of 'MWS' receiver)
A BB stopper is fitted to prevent too many BBs dropping when removing the magazine
Includes rear shim, one set of spare feed lips, one set of side shims, a longer valve knocker for certain non TM MWS clones, and all screws required to fit any of our modular magwell bases.
US Style HPA Fitting as Standard (most common fitting across industry - compatible with all AIRTAC HPA equipment)
