Good day to all, newbie here and have lots of question regarding ebr. what I have is an M14 springfield 22" standard barrel and I would like to have it face lift. My questions are 1. What is the EBR model that have magpul PRS attach already ? 2. Is it a plug and play or do I have to send it to a gunsmith to install ? Hope someone can help me on this matter. Thanks in advance
