Positive detents keep the MBUS Pro Front and Rear at standard AR sight height when deployed, and so low when they are stowed that you’ll never notice them until they’re needed. Narrow width Front is compatible with most IR aiming laser and light installations for the professional user.\r\nFeatures\r\n\r\nAll steel construction\r\nSteel, rectangular sight post selectable between Match and Standard widths .040\
