Bumpers owners would get $ 150 for their devices – so there was enough to buy back 1,000 devices.
Someone could bring up to five bump stocks and receive a voucher for each one on a first-come, first-serve basis. Authorities sent the individual a check in the mail after their voucher was processed
The program ran out of money at noon Monday, on the final day of the buyback. The devices kept rolling in, but those owners were not compensated. Some people took them home when they learned they wouldn't get a check, officials said.
State Patrol spokesman Chris Loftis tells CNN most of the buybacks came along the interstate 5 corridor, which runs north to south along the western portion of the state.
"We had a number of cases that people brought in only five devices," Loftis says. But he says they may have had even more bump stocks in their possession. Authorities collected "a number of homemade devices" that fit the description of a bump stock.
The devices are meant to replace the standard stock and grip of a semi-automatic rifle. They attach to a rifle's receiver, or frame.
The bump stock uses recoil effects to bounce the rifle off the shooter's shoulder and bump the trigger back into the trigger finger. This speeds up the rate of fire would have been without the bump stock. It effectively mimics fully automatic gunfire.
The Justice Department of owners should have one of two things at Tuesday: Destroy the devices, or drop them off at an ATF field office.
The Washington State Patrol said it will continue to accept bump stocks, with no penalty against the person dropping them off, but they can't pay anything for them. All such devices will be destroyed
