After researching for hours on this site and others about the Mk13 I came up with a disappointing lack of information. I'd like to start a website page soon with comprehensive guides on how to build replicas like the Mk13, and since it's my favorite I've decided to start with it. When doing my research I came up with a rough draft on the guide, but I need a lot of help filling in the blanks. The goal is to have a place to go with all the information and more to make a 100% accurate replica without having to visit 5 different forums with varying degrees of accuracy.
Here's how it will work, I'm just going to go over the currently known build guide I compiled over hours of research. Below the build I will ask questions and seek clarification on many things, if you know the answer just leave a reply and I'll update the original build guide. This method should crowdfund a very accurate build guide which will hopefully get picked up by Googles search results so people have a much easier time building their replica. Please say if you see something wrong, much of it probably is, all of this info is copy pasted from various sources including some questionable ones such as ar15.com. If you want to just chime in and talk about the Mk 13 in general or add any interesting facts feel free! Thanks.
