A bipartisan bill in the U.S. House that would remove firearm suppressors from National Firearms Act regulation after 82 years has picked up a number of new supporters.

Introduced last October by U.S. Rep. Matt Salmon, R-Ariz., with 10 co-sponsors, the Hearing Protection Act of 2015 last week picked up its 50th lawmaker to sign on in support. This gives the measure the backing of representatives from 29 states including one Democrat, Rep. Peter DeFazio of Oregon.
