High definition thermal lenses for masks Proto Switch EL, Proto Switch FS and Proto Axis Pro.

The BT TM-15 is THE choice for any hardcore woodsball or mil-sim paintball player. Its high performance magnesium body is strong, yet light enough in weight for all-day action. Equipped with features usually found on much more expensive markers, the BT TM-15 features a true electropneumatic operating system as well as reduced sound signature for stealth firing in any of the multiple firing modes. With the standard multiple Picatinny rails, accessory options are nearly endless. Internal airline operation eliminates external hoses. Flip up front and rear sights let you choose traditional sighting or stow away for sight clearance.
