Description
Galaxy M82 Sniper Rifle Co2 Conversion Kit
This kit is listed as a CO2 conversion for the Galaxy M82 sniper rifle. The Galaxy M82, model G31, is a spring-powered bolt-action airsoft rifle styled on the M82A1 heavy rifle, with a 30-round magazine, a metal cylinder and trigger, and a polymer body. A conversion kit lets an owner run the rifle on CO2 instead of a spring.
Gas-powered bolt-action rifles are popular because they cock with very little effort and are not affected by spring fatigue. CO2 is also less sensitive to cold than green gas, which suits UK weather.
Before you buy
The exact contents of this kit, how it is installed and the power it produces are not stated in our listing. Changing a rifle’s power source will change its muzzle velocity, so any converted rifle must be chronographed and set to meet the power limits at the sites where you play. Please check the product photos or contact us before ordering, and have it fitted by a competent technician.
About the Galaxy M82
The G31 is a large rifle, around 1.4 metres long and about 3kg, which splits into two sections for transport. Its long top rail takes most scopes, and its length and weight make it best suited to supported shooting from cover, prone or on a bipod.
