** FireFly Buckings are very hard to install on KWA guns. They are very tight and require use of silicone lube and extra care. ** The packaging will disagree (if you can read Japanese) with what we are recommending (but this is why you buy from Trinity). Our recommendation is from our experience with our personal airsoft guns, and those that contact us wanting to exchange hard for soft. Every airsoft gun is different, but our experience is that under 390 fps you need the soft bucking; over 420 fps you need the hard. Anything in between is in between.
