Nope, on the MAKs you must remove the trigger group before the safety can be rotated up and removed. I actually like that feature better since it doesn't rely on the top cover to secure the selector lever. When you install the Tapco group this changes and the only thing that keeps the lever from rotating up is the cover.
One other thing that the instructions are wrong about is how you should deal with the retaining wire. To properly use the retaining wire as designed it doesn't have to be removed. I wrote some instructions on another thread a little while back, that greatly simplifies the task of removing the FCG pins. Most instructions you read online or in print make it out to be a nightmare, but that is because they simply do it wrong. Oh well.
I'm surprised that you found the Tapco to be a great improvement over the original Chinese FCG. The Chicoms are generally regarded as one of the best AK triggers available. I didn't find the Tapco to be bad but I would still rank the Chicoms as better, plus they are milled forged steel as opposed to the cast Tapcos.
