If you are someone that has always wanted to have the performance and versatility of an HPA system but just couldn't bear the thought of being tethered to an airline or having a tank screwed into the back of your rifle, then the CGS™ was designed specifically with you in mind. Externally the CGS™ is manufactured using a real Milspec buffer tube blank which has been modified to conceal an adjustable regulator and CO2 cartridge which allows you to run your HPA system while retaining the same realistic appearance and the use of traditional Milspec buttstocks.

Its integral regulator shares the same internal design as PolarStar's other compact regulators and delivers performance on par with systems twice its size. This regulator has an output pressure range of 40-130psi which is easily adjusted using a 3/32 allen key but can be locked out using a standard chrono zip tie which blocks the adjustment screw. Additionally, if you want to get a little more "omph" out of the regulator, you can install the High Pressure Spring (p/n 10000692)* which boots the maximum output pressure to approximately 200psi.
- Machined from a Milspec AR buffer tube blank.
- Compatible with Milspec AR stocks.
- Simple zip-tie lockout/tournament lock.
- Incorporates PolarStar's proven compact regulator design which uses only 2 o-rings, promoting reliability and ease of maintenance.
