Unless you want the look of a silencer it does nothing to suppress the sound, I put one on mine to try. Most of the sound is from the open breach on the side, the valve is right there. If it lengthens the barrel you may get better accuracy thou.
I usually shoot .25's which are super accurate out to 50-60 feet then drop off.
I like the CO2, alittle more expensive but you fill half as much , and can carry a spare CO2 in your pocket , just in case.
