Lantac USA posted up a photo of a new AR BCG that has an external handle.
This unusual looking BCG turns your AR into a bolt action rifle when built into an upper with no gas system installed.
My friend Brian M. turned his .300blk AR into a bolt gun by simply blocking off the gas port in the barrel and eliminating the gas tube. He did this to comply with PA State hunting laws so he could have a manually operated firearm for hunting deer or coyote.
One problem that he had was the lack of direct control of the BCG. The charging handle could pull the BCG back but he did not have anything to manually push the BCG forward. He relied on the buffer and spring to close the bolt.
Having a manually operated upper could come in handy if you live in CA or NY state. As manually operated firearms are exempt from any silly assault weapon compliance issues.
Hopefully, we will see this at Shot Show next week and see how much it will be.
