Last year Adcor Defense released their B.E.A.R. gas piston rifle. I really liked what I saw so I decided to return to their booth and see what they had to offer this year. What I found was the new B.E.A.R. G.I. models which are direct impingement rifles. Once again, Adcor has done something a bit different though. They have made an adjustable gas tube which can easily be removed from the firearm for cleaning without the need to remove your gas block. It’s a pretty trick new system.
