Schmeisser SP-15 Straight-Pull AR-15 With Primary Arms SLX-1x Scope At 300m

As part of a previous video, I zeroed my Schmeisser SP-15 Straight-Pull with GGG 55gn .223 Rem / at 50m according to what the manufacturer says about the reticle of the Primary Arms SLX-1x single-power scope. How does it hold up at 300m? Does the BDC reticle do what it’s supposed to? And how does it fare with 77gn MK262 Mod 1C? Earlier video at 50m: Utreon: Patreon: Teespring: Instagram: Facebook:
