BT TM-15 Performance

The secret behind BT TM-15’s popularity in all scenario games is a high performance that is rivaled by very few markers in the market. One of the best features of this gun is its air efficiency and consistency. The interior airline ensures that no air sips out of the marker, which helps to economize on-air usage. BT TM-15 also operates on low pressure between 180-200 PSI and you even have the benefit of adjusting and visually monitoring the pressure through the gauge on the ASA regulator.
It comes with three firing modes: Semi-auto, PSP Ramping & NXL Full Auto plus a Safety mode, which is activated by a four-position selector switch. The TM-15 is electrically powered by a single 9-volt alkaline battery that is conveniently installed in the magazine. On the right side of the marker is a button that is used to dislodge the magazine for easy installation and replacement of the battery.
The gun also features an LED indicator that is used to indicate the battery life: green means the battery is good, orange means the battery is fairly depleted, while red means the battery is dead. It only utilizes compressed air/nitrogen, which means that you will not experience the limitations of C02, such as poor airflow as a result of temperature fluctuations. Besides, the TM-15 boasts of an adjustable buttstock that allows it to accommodate various wingspans for a comfortable fit.
The rear and front sights are also adjustable to improve the field of view. The sights can be folded down or removed when not in use or even moved anywhere along the top picatinny rail for the perfect FOV. The Hall Effect Sensor Trigger system is one of the best features of the TM-15. It comes with 4 adjustments for activation point, forward movement/stop point, return spring tension and rear movement/stop point for stress-free trigger experience.

Invert Mini’s electro-pneumatic marker engine is the highlight of this gun, as it allows the TM-15 to register one of the smoothest and quietest operations ever recorded in a paintball gun. This gun is very quiet and comes with accuracy, less recoil and a long range of up to 150 feet thanks to the 14-inch barrel. Compared to the highly-rated A-5 Flatline barrel, the TM-15 barrel shines edging the Flatline with more than 10 feet of distance. Your opponents will not stand a chance on the battlefield with this gun, as they will not know what hit them.
Another great feature is the anti-chop break beam eye system. Activated automatically when the marker is turned on, the break beam eye determines the presence or absence of a ball, which helps to reduce paintball breakages and allows consistent rates of fire. You can also adjust the velocity of the shots with an Allen wrench through the bolt guide cap, which allows you to increase (loosen screw) or reduce (tighten screw) the speed of each shot
