Rep. Steve Stockman (R-Texas) is raffling off an AR-15 semi-automatic rifle through his House campaign. Some Democrats want to ban this type of weapon. 

"Want to give Mom the perfect Mother's Day gift?" Stockman tweeted on Friday. "Win her a FREE AR-15! I'm giving one away!"

The tweet links to a raffle on Stockman's campaign website seemingly designed to cull supporters' contact information for future fundraising.

"Enter the drawing to win a FREE Bushmaster AR-15 rifle, almost impossible to find in stores and the number one firearm on the gun banners' wish list!" the website proclaims.

The AR-15 is similar to the weapon used in the Sandy Hook massacre and would be one of the weapons banned if an assault weapon ban went into effect — something that's highly unlikely as Congress has failed to act on much narrower gun control measures.

The winner for the raffle will be drawn on the Fourth of July.

One caveat: Winners will be subjected to a background check from a licensed firearm dealer.
