The B.E.A.R.™ Story

 

A New Perspective on the Automatic Rifle: The B.E.A.R.™ combines design innovation and precision manufacturing built upon the tried and true M4/M16 rifle platform.

The Adcor Defense B.E.A.R.™ springs from the M4/M16 rifle platform but offers a completely new twist. Available in many configurations, it offers the operator many significant improvements:

 

A Revolutionary Gas Piston System (Patent # 065111.00128)

  • Free-floating barrel and increased accuracy: A gas-driven piston incorporated into the upper half of the forward rail system never touches the barrel.
  • No carrier tilt: The operating rod is connected to the bolt carrier by hex head bolts reinforced with industrial grade Loctite® 262™ high strength threadlocker. They are then drilled and pinned to prevent loosening under adverse conditions.  The operating rod then rides through a machined boss in the receiver rail system interface keeping the bolt carrier in a linear plane as it operates.
  • No fouling of chamber and action: Hot gases and carbon particulates are prevented from entering the receiver. Because heat reaching the upper receiver is diminished, lubricant lasts longer and maintenance is simplified.
  • Easily detached lower rail system: No special tools needed for quick cleaning and easy maintenance.
  • Wear on critical parts is minimized: The operator can easily adjust the piston’s cyclical rate for a controlled rate of fire.
  • No need for piston rings: Extremely close machine tolerances of the piston eliminate the need.

 

Exclusive Port Dust Wiper with Cover

  • Prevents entry of dust, sand or debris: The spring-loaded dust shield mounted on the bolt carrier allows the bolt carrier’s return to ready position; the port dust wiper moves into the ejection port opening flush with the inside geometry of the upper receiver.
  • Withstands temperature extremes because of the highly durable, self-lubricating polymer shield.

 

Ambidextrous Forward Placed Charging Handle: Simplicity is Beautiful.

  • Simple design allows the operator to keep his or her strong hand on the firearm and use the other hand to clear the rifle.
  • Ambidextrous handle detaches easily without special tools and returns to locked position once used. It folds forward, recessed, and easily swings back out in a single motion.
  • Non-reciprocating handle only engages when the operator charges or clears.

 

Rail System ( 7075-T6 )

  • Innovative, key locked, highly rigid rail system mounts seamlessly to the upper receiver: Design ensures proper alignment of the rail with a redesigned boss, spline and groove system.
  • Upper and lower rail guards separate with the push of a button: No special tools necessary.
  • Fully compatible with optical, image intensification or thermal sights; laser targeting systems; bipods; tactical lights and Multiple Integrated Laser Engagement System (MILES).
