CNC Aluminum Rotary Hop Up Chamber M4 - AR15 PRO.
This Hop Up chamber is a slightly redesigned version of the RetroArms hop up Basic chamber.
It is machined on a precise CNC machine from aviation grade duralumin EN AW 7075 and anodized.
This hop up chamber is R-hop (Rotary) ready and is meant to be used in setups, which have troubles with magazine
installation in the body, which are not unlocking and feeding.
The feeding shaft screwed in without any shims sits in the same position as the shaft of the Basic hop up chamber.
The height of the feeding shaft can be adjusted by 0.2 mm increments with included shims.
After assembly and tuning we recommend securing the adjustable feeding shaft with medium strength thread glue.
On a feeding shaft, you can find an o-ring, which prevents those "usual" 4bb from falling out when reloading.
Another feature is a collet nut instead of a centering ring in the front of the chamber.
When the collet nut is tightened, it holds the inner barrel and the chamber tightly together and thus mitigating any movement of the barrel.
Just make sure that you do not let the barrel rotate in the chamber when you tighten the nut.
Another advantage of this nut is that it can hold barrels with different outer diameters, typically 8.4 - 8.5 mm.
Recent fine tuning of the main shaft and feeding shaft ensures compatibility with most hop up rubbers and improves feeding
reliability and consistency of the chamber.
The adjustable feeding shaft part is identical with the one on the Ultra version.
Weight: 18gr.
