TECHT L7 H.E. Bolt System G4/G3 Spec-R Engine Review

This works awesome in my G-4. My gun is more quiet, uses less air, there is less kick when I fire it, and no more bolt stick. Before I changed bolts I was shooting at 285 fps, and after the install I shot at 390 fps and didn't break any balls. So don't forget to lower your reg pressure. Also, u tube has some helpful info on doing the conversion.
