TechT Paintball Products has been making the best upgrades for the Invert MINI and the Empire AXE since their release. We could see that these guns had major potential, but needed some help. We have produced the parts we felt the markers need, and nothing they don't. Come on an adventure of discovery and success with full line of upgrades from TECHT. All TechT products come with a warranty and a piece of mind that your gun will be made better by our products. You can put a cost of upgrading your paintball marker, but you can't put a price on the joy of winning and shooting more dudes in the face.
