All Weather Performance Thanks to its unique Mag Chamber design combined with its pressure compensating valve, the Viper M1 is immune to extreme temperature changes. Theirs can freeze below 40 degrees, while hot weather can create surges in velocity that can result in game penalties. The Viper M1 features a fast and simple microflow velocity adjuster which is set with the slight turn of a screw. Complex adjustments of hammer and valve springs waste playing time. Improper spring pressures hinder semi-automatic operation.
Any paint left by defective balls is gone in seconds.
The Viper M1 is back together and firing while theirs is still in pieces. Lock pins, allen screws and threaded barrels take longer to remove. They also lack open access to the breech which must be cleaned seperately. All American made, the Viper M1 is built from durable lightweight aircraft-quality aluminum. The Mag Chamber and powerfeed are dip brazed to rigid US military specifications.
