Impact Arms Gas Impact 2.0 comes straight from the same manufacturer as Nuprol.
Impact arms recommended to keep the bottle size of the manufacturer namely 1680ml instead of the 1000ml on the market.
The 2.0 gas at a pressure of 1Mpa at 25C °, it is slightly silicone, not as strong as the Walther but rather similar to the ultrair.
This gas is generally used with GBB metal cylinder but, after installation of a reinforced bolt return spring, we use it in GBB Tokyo Marui without problem.
The use of this gas is made for temperatures between 20 to 40C °
Impact gas is attentive to the ozone layer and is therefore CFC-free for safe use.
