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

"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.
