The Special Purpose Rifle (SPR) has gained in popularity with shooters in the civilian and law enforcement community. GG&G's technical advisors suggested that the scope most often used on SPR rifles is a 30mm low powered variable optic placed forward on the AR-15/M16 flattop receiver. To meet the specific optic mounting needs of the SPR shooters, GG&G has introduced the GG&G FLT Scope Mount with 30mm Integral Rings.
