First AR-15 - Everything You Need to Learn and Train | Palmetto State Armory
This guide focuses on building a first AR-15, emphasizing practicality and fundamental training. Key recommendations include a 16-inch Nitride barrel with a 1:7 or 1:8 twist, a free-floated M-LOK rail, and a quality, MPI-tested Bolt Carrier Group. For optics, a red dot sight is suggested for beginners, with LPVOs as a step up.
