If you feel when shooting your KJ 1911 (magazine full gas), but... ●Recoil is weak... ●BBs always drop down early...
That's because the gap between the magazine and the nozzle is too large, which leads to the above issue. Don't worry about that, T-N.T. show you how to fix it!!
1. First, dissemble your KJ 1911.
2. Dissemble the slide and take out the nozzle.
3. Prepare the marker pen and the acrylic sheet (thickness about 0.5-0.6mm).
4. Measure the width of the gas inlet.
5. Marker on the acrylic sheet. (with gas inlet)
6. Cut it off and use the rasp polished flat slightly.
7. All sides must use rasp to chamfer, like the photo. (side view)
8. Use a rasp to grind the gas inlet slightly, make the joint surface rougher slightly.
9. Use super glue to bond the acrylic sheet on nozzle.
10. Use the rasp to slightly polish the four sides to make it smooth. (side view)
11. Assemble all parts, smear a little silicone oil.
