I have two kits (Bulgy AK74, AMD63) that are getting the itch to be put together. I have read several threads here and at other forums. I remember one forum matching up some competitors receivers and giving you the rundown, but I can't find it. I really don't want to mess this up. Some of you have said that the Vulcan brand is junk because of the soft ejectors and mismatched front trunnion holes. And still others complain that the OOW receiver has the safety hole in the wrong spot? The ACE is %80. What IS completed on it. I am leaning towards the OOW brand right now but would like to know how they have worked on kits similar to the two I have hidden from my wife (I think). Basically, what will give a first time builder the least trouble. I am set up for screw builds if that helps and my drill press wants me to come and pick it up from Home Depot. Thanks for any info you guys can give.
