When switching to HPA, there are two schools of thought: those who build their setup piece by piece… and those who want a clean, efficient and immediate solution.
The Polarstar MRS HPA Regulator + 42" hose clearly targets the second category. Here, everything is designed to offer you a complete, compact and perfectly balanced system right from installation.
Regulator + HPA line + quick coupler… you connect, you adjust, you play. Simple. Efficient. And honestly enjoyable.
A compact and ultra high-performance regulator
Here we find the famous Polarstar MRS regulator, known for its reliability and precision.
At only 7.5 cm in height, it screws directly onto your HPA tank without weighing down your equipment. Result: a lighter, more discreet setup, and above all better balanced on the field.
But don’t be fooled by its compact size… the MRS delivers serious performance.
Adjustable pressure to match your gameplay
The regulator offers an adjustment range from 40 to 145 PSI in standard configuration.
CQB, woodland, DMR… no matter your style, you can quickly adjust your pressure to adapt your replica to the situation.
And for more demanding setups, a high-pressure spring (optional) allows you to go up to around 200 PSI.
Clearly, this is a regulator capable of keeping up with all your playstyle needs.
Consistent air flow, even at high rate of fire
Thanks to an enlarged piston, the MRS ensures high air flow and an excellent refresh rate.
Concretely? Even in bursts or fast semi, your replica remains consistent. No pressure drop, no shot variation… just smooth and steady feeding.
This is the kind of detail that makes the difference between a good replica… and a perfectly tuned one.
42" hose included: total freedom of movement
This is where this kit really makes sense.
The 42-inch (107 cm) hose offers an ideal length to play comfortably without constraint. Not too short, not too long… just enough to move freely without discomfort.
Combined with a 6 mm quick coupler, it allows a simple, fast and secure connection to your replica.
You gear up, you connect… and you’re ready to hit the field.
ON/OFF valve with depressurization: a real everyday advantage
Polarstar has integrated an ON/OFF valve with depressurization, and honestly… once you’ve tried it, it’s hard to go without.
It allows you to release pressure before removing the regulator:
Less effort during disassembly
Protection of seals and threads
Safer handling
It’s a small technical detail… but a huge improvement in everyday use.
Compatible with all HPA and SLP tanks
The MRS works with:
Standard HPA tanks
SLP systems
So you can easily integrate it into your current setup, without any particular constraints.
A secure system for regulated fields
The locking ring allows you to lock the pressure setting with a zip tie.
Convenient for complying with limits imposed on certain fields or events. A simple safety feature, but essential for playing with peace of mind.
Why choose the Polarstar MRS + hose kit?
Because it offers everything you expect from a modern HPA setup:
Compact and reliable regulator
Precise and stable pressure
Hose included for immediate use
Simple installation
Maximum compatibility
It is clearly an ideal solution for players who want high-performance equipment without complicating their setup.
And between us… when everything works perfectly from the first game, it changes everything.
