Hello mwes1987,
The Proto Rail 2011 has been very popular this year and is a great entry level gun. There are some great features on the Rail such as the self-cleaning EYE pipe, Ultralite frame and clamping feedneck. It also comes with all the fire modes you would need to play any tournament series.
The Proto Reflex is essentially the Rail's bigger brother, with additional features like the matching two peice 14'' barrel as standard, a Proto on/off airport, aluminium clamping feed neck and Ultralite frame. Again, its fully programmable for all fire modes. The main functional difference is that the Reflex solenoid allows the Reflex to achieve higher Rates of Fire than the Rail, and gives a slight increase in efficiency too.
Depending on what you play - woodsball, walk ons or sup'air - both these markers are well suited for all occasions.
If you want any more information or if you have any questions please feel free to post here or PM me.
Thanks!
