MARKER REVIEW 7 : BT 4 COMBAT

BT 4 COMBAT ( Offical Marker at Jahang River Paintball)

The BT-4 Combat is the second generation of stock markers released by BT paintball. Very similar internally to the Tippmann 98 Custom, and aesthetically very similar to the Tippmann A-5. Its unique feature is that it is the base, or core, of most of all the other BT markers (Save for the TM-7 and BT-16); with fancy upgraded markers like the Delta Elite simply being BT-4's with stock add-ons.

The BT-4 uses the same barrel thread as the Tippmann A5 and the stock (butt) mods of the Tippmann 98 Custom. The barrel thread is also designed to be swapped out so that you may use barrels from other paintball markers.

The Bt-4 Combat is generally enjoyed for its durability and customizability, with a large host of aftermarket add-ons available. Since it is similar to the Tippman98 Custom, it can use many of the same parts and accessories.

The Bt-4 Combat is a poppet valve, blow-back marker. This means that the bolt slides forward to open the valve, and air released from the valve both propels the paintball forward and recocks the bolt for another shot. While this setup is generally quite durable, it generally is louder and less gas efficient then a non blow-back marker.

The main features of a stock bt-4 combat are its adjustable handgrip, adjustable rear sight, sliding feedneck, and 8 inch barrel.

The BT-4 Combat is the choice of demanding players who are looking for a solid and cost effective base to build up with custom parts with the ability to use military spec features. The combat comes with BT reliability and battle tested durability.
