SPR Special Purpose Rifle

The Special Purpose Rifle is based on the special operations Mark 12 Mod X. The SPR was designed to be an intermediate sniper / designated marksman rifle. The 18” match grade 1-7 twist barrel offers exceptional accuracy with heavier bullets making it a more effective long range rifle. The rifle length T.R.I.M. rail offers extreme versatility for mounting mission essential equipment such as night vision, bipod, tactical light, secondary optics, etc... The SPR is equally at home as a sniper / designated marksman rifle, on the range or as a long range small game hunting rifle.

    Raddlock Magazine Lock Button AR Upgrade for California Residents

    To help our customers maintain compliance with California law we are offering the Raddlock Magazine lock as an upgrade to Wilson Combat Custom AR Rifles sold in that state.

    The AR Raddlock Magazine Lock Bullet Button provides a unique two-position operation making it one of the most flexible designs available for use on California legal AR rifles and is precision machined from 6061 aircraft aluminum with hard coat anodizing.

    Position 1 acts in the same way as any of the other bullet button locks in that the magazine can only be removed with the use of a tool.

    Position 2 allows the AR Raddlock to be activated with a press of the finger, just like a standard magazine release button. Position 2 is perfect for shooting outside of California or when using a .22 rimfire upper. Never use position 2 inside California with a centerfire upper and any banned features installed on your rifle as that would construct a banned assault weapon and is punishable by California law.


    This lock kit has NOT been approved by CA DOJ. This magazine lock has been designed to conform to the law as written in CA Penal Code § 12276.1 (a) which defined ""detachable magazine"" as any ammunition feeding device that can be removed readily from the firearm with neither disassembly of the firearm action nor use of a tool being required. Title 11 CCR § 5469 (a) ""A Bullet or Ammunition cartridge is considered a tool.""
