Redline Airsoft Mini SFR Air System (Model: HPA Engines)

"Works pretty well, easy to adjust, I noticed better shot-to-shot consistency on my Gbbr when using full auto. However, it is pretty difficult to take on and off so I just turn the PSI down and leave it on.

"I bought the regulator and the line. First off, the regulator is extremely compact and simple to use. I could give it to my 8 year old brother and he would be able to adjust the psi. Compared to other regulators I have seen, it is much more compact. Has less potential to get caught on something and/or break. The refresh rate is amazing. I am using a H&K army 48ci Aluminum tank and I have had no problems. The line is what you would expect it to be. Works flawlessly, would recommend it to anyone who is willing to spend a little more that $85 for the amped regulator and line.

"My regulator shipped next day and I paid for 3-day shipping, ended up getting to me within 48 hours!

Regulator is great too, for an easy plug and play system for Polarstar you really can't go wrong with this set up. Came out of the box set to 80psi and came with the allen wrench to adjust pressures. My only complaint is the shipping costs, however, seeing as how quickly it got to me I can't really be mad.

10/10

"The reg does what it's supposed to. When you set a psi it stays there and does not lower over time like some other cheaper regs. The allen key adjustment socket is extremely tight and squeaks when you turn it, but I would rather have it be super tight than be super loose. Also for whatever reason the interior allen socket is not to spec so keep the tool it comes with when you get it because from what I have tested nothing else fits so don't lose it.

"Overall a wonderful regulator doing what a regulator is supposed to do; keep everything from being shot out the barrel from over-pressurizing the gun and keeping the HPA engine working with enough pressure in it.

I have used this regulator on several guns, with varying HPA engines and have not once had any issues.

The lowest PSI I have ever used it on was 40 with a Redline N7 Milsim system for an indoor event where I was required to be about .5 joules with a .25 bb

The Highest PSI was on the same airsoft gun with the Redline N7 Milsim and 115 PSI for an outdoor event where I was classed as a DMR. Shooting about 2.81 Joules with a .40bb

Have also used this regulator on a Polarstar Kythera around 90 PSI and have never had any issues with it. On the Kythera the only problem is while this regulator will work down to about 40 PSI the Kythera does not; it needs about 80 PSI to function properly so make sure when you get an HPA engine you check the recommended PSI operation range before you ruin the system by going above or below it.

The built in tourney lock does work but I have only ever been able to use smaller zip-ties with it. Some of the normal size will fit but large ones do not.

One complaint I have about it is depending on the line you use (hose going from regulator to gun) it can be a little loose and will leak some air when first attaching it. I have found twisting the connection pieces (quick connect male and female ends) will stop the air leak.

"Been using this for almost a year now so review is based on overall experiences.

PROS
1st: It works extremely well. I have on a ninja 68/4500 slp carbon fiber tank and have not had any issues with airflow

2nd: Super easy to adjust the output psi to what you desire and works well at both higher and lower psi (tried everything from 75-150 psi)

3rd: Easier than most regulators to put a tourney lock on (most fields will require)

CONS
1st: The included line after a while will start to wobble a bit when connected to the regulator allowing a minute amount of air to leave through the plug in port...easy fix get a new line

2nd: Can be difficult to attach to your HPA tank due to it being a snug fit

Overall I would recommend this to anyone looking to run an hpa with high rate of fire or a cqb style gun where you need a lower pressure
