Kyle and a CO2 to HPA Converted Hammereli 850 Magnum

The Hammereli 850 was a Co2 powered bolt action with 13fpe. It was very accurate but borig since the low power. It was already modded with a 2 stage trigger and a large CO2 tank. I decided to convert it to HPA. The HPA tank has been regulated to 1800psi and a heavy hammer spring has been added. The reults are fantastic. It's now 26.5fpe and still very accurate. This is Kyle at 10 years old with just sights hitting the target 60 yards away.
