"Precision AR-15: Concept SPR" by Nutnfancy
Nutnfancy reviews his custom SPR build, a lightweight AR-15 concept based on the Mark 12. He emphasizes the importance of weight management, aiming for an SPR that doesn't exceed a standard AR-15's weight. The build features an 18-inch Sabre Defense barrel and achieves 1 MOA accuracy with match-grade ammunition, though it struggles with lighter loads.
