Hi, I have been doing quite of bit of reading. I am considering building an AR. I was able to swap out the trigger spring and connector on my Glock 30. An AR has about the same number of parts as a Glock, right? But seriously, I have been watching lots of great how-to videos on YouTube. I am confident I can put one together. It's just a matter of researching the best parts. I plan to purchase a few parts each month. Right now it seems like everything is on back-order.
