“Precision AR-15: Concept SPR” by Nutnfancy

The SPR Concept has validity. A lightweight 5.56mm 18″ barreled precision AR-15 or M16 variant rifle will offer somewhat improved ballistics, more lethality, and perhaps better precision. Most identify with the SPR as the US Army or US Navy Crane produced Mark 12 SPR in its various iterations. “Concept SPR” begins with an interesting discussion on the Special Purpose AR-15/M16 Rifle and its application, delineating fact from fiction on the SPR. Special emphasis is placed on the limitations of the .223/5.56mm cartridge in long range engagements. I concentrate my efforts and build is in Real World Application of the Special Purpose Rifle; gladly abandoning any attempt to duplicate a Mk 12 in the process. I am not in agreement with several of the component choices of the Mk 12 based on both cost and ergonomic considerations. Moreover I remain a non-worshiper of military adoptions realizing the innovative and unconstrained civilian market is superior in almost all respects. Instead I look to lightness, accuracy, durability, and top shelf ergonomics in the modifications of this rifle. This version of a TNP SPR, built on the Sabre Defense SPR #90116 model, achieves all of that as shown and weighs in at 6 lbs 14 oz with BUIS. This below most other 16″ barreled AR-15 carbines. Components are shown and discussed in detail and its two years of shooting performance in TNP is the foundation of the review. Some will spend extraordinary levels of money to replicate a military Mk 12 Mod 0 or 1. I consider this a fool’s errand unless the individual throws out the Second Kind of Cool flag (criticisms off limits then). You’d be better off to focus your build along this concepts shown here. In terms of capabilities and ergonomics, this super lightweight, fast, reliable, and accurate SPR meets and/or surpasses the vaunted Mk 12.//////////////////////////////Nutnfancy Likability Scale on TNP SPR: 10 out of 10
