Tried this trigger out on my PM63 build and it fit like a glove. I didn't even need to add the roll pin to that came with it as there was almost no play when in the safe position. Once installed and lubed up properly it has no creep with the cleanest break followed by a crisp reset that I've not experienced with any other AK trigger. I like my Tapco G2's but this one may just go on all my competition AK's. Only time will tell of it's reliability and ability to take abuse. Until then, it tops my trigger list.
