PolarStar Concave Spacer (PCS) High Performance Airsoft Hopup Spacer
UPDATE! The PCS is now produced under license and in cooperation with Shredder's Concave Spacer (SCS)

1. Why is the PolarStar Concave Spacer (PCS) the #1 Player Recommended Product in Airsoft?
The PCS replaces the stock hop-up nubs/spacers that come along with Airsoft AEG's and Airsoft Sniper Rifles. Each PCS is precisely CNC manufactured to meet PolarStar's exacting standards and are individually inspected to ensure a precision product. This careful attention to detail ensures each PCS produced maintains a superior level of construction and quality control over other hopup spacers. Although the basic concept is not new to the airsoft industry (H-nubs, Bone nubs, etc) the innovative team at PolarStar created what we believe is easily the best designed hopup spacer in the entire airsoft industry! Do not be deceived by similar products. Get the best there is! Ask around and you'll hear how this one aftermarket upgrade part has improved the performance of thousands of airsoft guns worldwide!

2. What is the PCS made of and why?
The PCS is made from a special engineering plastic which is light, flexible, chemical and wear resistant to create a durable, long lasting hopup spacer.

3. Is the PCS better than the other nubs and spacers out in the market? Why?
Absolutely! The PCS is hands-down the best hopup spacer on the market! The reason is that out of all the designs and measurements, the concave shape of the PCS and its wide curving surface provides the BEST hopup rubber bucking to BB surface contact. This solid contact centers the BB inside the barrel and eliminates the excess lateral movement as the BB passes through the hop up bucking. None of the other hopup spacers come close to the quality and performance of the PolarStar Concave Spacer (PCS).

4. What airsoft guns can I install the PCS into?
The PCS can be installed into any airsoft electric gun (AEG). The PCS can also be installed in most airsoft sniper rifles and submachine guns. When you need extreme accuracy and unparalleled precision choose the PCS. Sniper rifles may require modification and should be installed by an experienced airsoft technician for maximum performance.

"I have this spacer in two of my guns. You have to modify your bucking in order to get the full increase in performance from this spacer (it involves turning the bucking on its side when installing, i'm sure you can find a guide for it online). However, it will still improve your accuracy even with out the bucking modification. This is the best spacer to use with any typical bucking, and especially with the bucking modification. I'm not sure how well it would be with a 2GX bucking, though I'm not sure.

"Will this fit in an ics mo5 hop up
I want to increase my accuracy . This looks like a great hop up nub

My friend has this nub and he got great results from this it's a 5/5 in his opinion

"Very nice nub. Probably one of the best on the airsoft market today because of the cheap innovation it offers. I found that if you super glue the nub in place, it still works, but its more consistent because it can't move (little mod for you gearheads out there). This isn't actually the best nub because despite popular belief, Angel Customs h-hop is probably better for consistency, accuracy, and range all around. Still, such a fantastic product so 6/5.
