Hey folks, My build is progressing, and I am getting ready to purchase my buffer, buffer tube and stock. I have read a bunch, watched a bunch etc, and basically from what I have seen, the jury is still out on "if" one needs to get a mil-spec tube and buffer... I am inclined to just get it to have the peace of mind regarding quality etc. That being said, I am open to your thoughts and opinions. What I am looking for are recommendations for me to either research or buy for the tail end of this lower build. Keep in mind, it's my first build, the intended uses for this rifle are as follows: 1. SHTF & Home Defense 2. Plinking and Range time with the family and friends 3. Tactical training and our course work 4. maybe more? ... hehe Thank you as always for any thoughts and pointers! This is clearly part of my advancing severe case of BRD... just say'in.
