Federal ministers played down notions Tuesday that Senate committee amendments to the Liberals' gun bill would hobble the legislation.

Public Safety Minister Ralph Goodale suggested the government's intentions for Bill C-71 will be reflected in the final version of the legislation, despite efforts by Conservative senators to cut provisions they say penalize law-abiding gun owners.

The government bill introduced last year would expand the scope of background checks on those who want to acquire guns.

Instead of just the five years immediately preceding a licence application, personal history questions would cover the applicant's entire lifetime.

The bill would also force gun retailers to keep records of firearms inventory and sales, and require the purchaser of a hunting rifle or shotgun to present a firearms licence, while the seller would have to ensure its validity.

The legislation has been criticized by gun-control advocates as too weak, while some firearms owners have called the bill an attempt to revive the ill-fated long-gun registry.
