Hitman mod on ER-2?
I recently acquired a pair of ER-2s to mess around with and play on my property (we don't have a place that fills CO2 up here, but 12ies are pretty cheap at the local Wal-Mart!). I was going to attempt to "Hitman mod" one of them so I can have a vertical foregrip. I know the cocking pressure is fairly heavy, so the standard steel wire wouldn't work without bending every shot. Any suggestions on techniques, materials, and such?
