Adcor Defense has been teasing on their Facebook page their “Dust-Wiper” polymer bolt carrier group. Originally introduced in their BEAR rifles, the polymer cover assists with “wiping” dust and debris from the bolt carrier during cycling after the dust cover itself has been released.
Their Facebook page has teased pre-orders, but the website does not currently have the cover or any pricing listed. Adcor has stated that they will be releasing complete bolt carrier groups and just the carrier.
Hit up their Facebook page for a chance to win the first cover off the production line.
