BT-4 Ironhorse
This is the marker that I won at D-Day 06' at Skirmish. According to the manual, BT (Battle Tested) it a different company from Tippmann. However, with the exception of the ball detent, (It's actually double sided and can be flipped over if one side wears out.) the internals are exactly the same. The marker looks like a M-4 Carbine minus the magazine which I now have. I had no problems at all with the marker. It works just like the 98C but has a greater advantage over it because of the features. The feed neck slides on and off insted of being on a hindge like the 98C getting rid of the hopper wobble. The removeable grip frame appear to be similar to the A5, but don't quote me on that. The best feature that the BT-4 has is without a doubt, the APEX barrel. This barrel is adjustible so you can shoot around corners, drop a ball behind a bunker from above, and the best feature, it shoots like a flat line. The range is insane. I was out shooting everyone. I had people unloading on me and falling 30 feet short. Yet with one shot I could make them duck. These barrels run about $80. I have one on my Grease Gun Tippmann. The BT-4 Ironhorse runs about $500, but I have seen it for as low as $380. Of course I'm not happy with the basic marker, so I added to it.
