#SpecialPurposeRifle

The AR-15 has become the most prolific modern rifle in America—and for good reason. Its modularity, accuracy, ergonomics, and proven track record make it a top choice for self-defense, competition, and professional use. But among all the possible configurations, there’s endless debate over which build is truly “best.” There is personal conjecture from both professionals and content ninjas alike. Today is an examination on the original modern-day patrol carbine, the MK12 SPR; more than a precision weapon, the SPR is the do-all shooter; the SPR is the multi-tool of ARs.

It’s always fun to present images on TFB’s Photo Of The Day that our readers cannot possibly have seen anywhere else or before. This is such an occasion, as these are brand new images of the Steen Defense SD-1 SPR, short for Special Purpose Rifle, that were never shown before.
