The ARSMC can bottom out just below the belt or drop a 30 round mag to a 50/50 position, that is the midpoint of the mag will be approx in the center of the belt. This substantially reduces the range of motion necessary to extract the mag and orient and reload your AR. This is normally custom looped for your particular belt or we can supply to fit Tek Lok of Molle. If not custom looped it will mount in standard position. The ARSMC is adjustable for retention to accommodate service or competition.
