Some state lawmakers plan to push the Oklahoma Firearms Freedom Act this session.
They say it'll prevent the federal government from interfering with residents' second amendment rights.
The bill would make guns and ammunition made in Oklahoma exempt from federal regulations.
A similar bill passed both the state House and Senate in 2010, but Governor Brad Henry vetoed it.
The Firearms Freedom Act was just one of hundreds of bills Oklahoma state lawmakers filed Thursday, just before the 4 p.m. deadline for legislature consideration.
Other bills were filed dealing with income tax policy, workers' compensation and abortion and gun rights for consideration by the 2013 Legislature.
Lawmakers typically introduce about 3,000 measures each year, but this year's final count will not be known until Friday.
Several bills were filed to address Oklahoma's income tax structure. One proposal from Republican Sen. Patrick Anderson of Enid would replace Oklahoma's 5.25 percent income tax rate with a flat tax of 2.95 percent.
Another bill, the Personhood Act of 2013, says life begins at conception and is similar to a bill that failed last year.
