The complete PR-15 HPA airsoft series were on display at the SHOT Show 2018 last month and Jonathan Higgs was there to check them out. PolarStar Airsoft is aggressively working with airsoft manufacturers to come out with complete HPA systems and they will be soon available this year. Also at the TopTech 101 booth which handles mainly G&G products and other brands are the new offerings from G&G Armament for Airsoftology to report in this video.
