Frequently Asked Questions

What makes the Adcor B.E.A.R. different from standard AR-15 rifles?

The Adcor B.E.A.R. features a gas piston operating system, unlike the direct gas impingement system common in AR-15s. This piston system isolates the barrel from hot gases and carbon, enhancing reliability, reducing maintenance, and improving lubricant longevity.

How does the B.E.A.R.'s piston system improve reliability?

By preventing hot gases and carbon particles from entering the receiver, the piston system minimizes fouling and heat buildup. This leads to more consistent operation, especially during sustained fire, and reduces the likelihood of malfunctions.

What are the benefits of the B.E.A.R.'s free-floating barrel?

A free-floating barrel design means the barrel does not contact the handguard or other components. This isolation allows the barrel to vibrate more consistently when fired, leading to improved accuracy and more predictable shot placement.

Does the Adcor B.E.A.R. have an ambidextrous charging handle?

Yes, the Adcor B.E.A.R. includes an ambidextrous, non-reciprocating charging handle. This feature allows the shooter to charge the rifle or clear malfunctions while keeping their strong hand on the pistol grip, enhancing operational efficiency.
