BAT Machine’s Model VR 2-Lug Short Action Repeater: A Remington 700 Size Action

July 25, 2014 Bill Marr Precision Rifles, Rifles 0

My friend purchased a BAT Machine Model VR short action (left-handed).  This action has a Remington 700 short action footprint so it will work with standard Remington bottom metal.

The Model VR action includes an integral rail, external bolt stop, and integral lug.  You’ll notice the bolt lugs are even with the bolt face.  This action does not require a bolt nose recess.  The action uses a tenon .776″ long with a 1-1/16″ x 18 thread.  Standard Remington 700s use a 1-1/16″ x 16 thread and have a longer tenon length determined by the recoil lug thickness.

In the pictures below you’ll notice it is well machined and finished.
