Product Description
The SPR concept was originally proposed by Mark Westrom, president of ArmaLite, while working at Rock Island Arsenal in 2000. The program was an outgrowth of the desire by both US Army and Navy special operations forces for a rifle with greater effective range than an M4 carbine but shorter than an SR-25. The SPR grew out of both the SOPMOD Block I program, and the U.S. Navy SEALs Recon Rifle, a 16" flat-topped M16 carbine. Early models included the SPR, SPR/A, and SPR/B. The Naval Surface Warfare Center, Crane Division expanded on the Recon Rifle. Now the MK-12 has been replaced by the SCAR MK-17.
To us this is exactly what the MK-12 program should have been.
