can you please explain what you mean? The draw on mine is SUPER tight
When you received yours, did you disassemble and clean it COMPLETELY? I mean every single screw and insulator needs to come out and be cleaned. The center post needs to be removed as I had some plastic burrs from the insulator lodged in the air hole in the screw.
1.) Take EVERYTHING apart, including removing all o-rings. Inspect the center pin and air holes, be sure to remove any excess plastic burrs.
2). Soak everything overnight in hot, soapy water.
3). Rinse everything off, then take a toothbrush and dish soap and get to scrubbing. Rinse again.
4.) Optional, but I then soaked everything in Vodka for a couple hours to be sure I got rid of any oils, scents, ect.
5.) Reassemble, and you are good to go.
Seriously, I own a legit KFL+ and R91. I now have 3 Blacks (loved the first so much, I ordered 2 more). The airflow on the Black Edition is just as good. Opened wide up, it is MAYBE the slightest bit tighter than the KFL+, if at all. However, if you aren't sure to clean it well, you probably won't be pleased with your airflow being blocked off.
