I am setting up to trim my top rails soon and was wondering whether there ia atrick to cutting them even on both sides, also, is there a way to get the proper placement for the center cutout(the bolt cutout I believe).

Any help would be appreciated.

Also, I was wondering how well the top rail layout jigs work, is there a chance of overcutting with these, and do they work well?

You can pretty much eyeball it if you are steady hand with a Dremel (that's how I did my first).  The best thing to do is use a marker or something to mark what needs to stay and then Dremel down to that.  But the jigs are probably the best, don't sweat it AKs are not that precise you will be able to do it just take your time.

+1 for what he said and I have the jig, I'm not sure it's any easrier it just makes a straighter line but if after you cut you use a long file it will be just as good.  Leave a little to file smooth and take your time.

okay, I just thought there might be some trick to it. I guess the first thing to do would be trim for the front for the trunnion and then start trimming the rest of the rails. One question, the cutout in the middle of the reciever, how do you know where to put that one? I believe it is for the bolt when you insert the carrier through the back cutout by the rear trunnion, I get that one, but how do I measure where the middle cut goes, and what exactly is it for?

Thanks

The specs are available here where the manuals are.  It is just the length of the bolt carrier that goes in the receiver from the rear trunion.

take your time,
you can always remove more, you can not add more.
also, dont cut out too much on th erear portion where the carrier enters. i did that and now need to mig weld in to replace the excess i took out

I understand the rear cutout, but there is another cut in the middle of the reciever, what is that for?

I think I get it.When you go to put the carrier in the slot in the rear you have to tip it down right? so the middle cut is for the actuall bolt to go inside, under, the rails, right?

I don't know about the tipping down part, but the slight cutout in the center is indeed for bolt clearance.

after the front trunnion is cut and fitted

cut for the rear trunnion and fit the top cover before you cut the rest of the rails
if not youll end up having a gap where the front of the cover meets the front sight base

then fit the cuts in the rails to the bolt starting at  the rear

okay, but what do you mean the center cut is for bolt clearance? why does it need clearance in that spot?

Just go to AKBuilder.com, he has a jig for cheep that you hold to the receiver and then make your line with a marker. Cut and then you have a pefect fit every time.

Took the dremel to the rails and it worked out fine, not as hard as I thought.
Thanks all.
