We’ve written about the X-Products Multi-Purpose Launcher, which launches tennis balls, and X-Products also has a Can Cannon which launches soda cans. Unfortunately, the Can Cannon costs almost $400 and the Multi-Purpose launcher costs $500. NcStar offers a much more affordable way to launch re-useable projectiles with an AR-15.
Check out the NcStar AR-15 Golf Ball Launcher, which only costs $24.99 and can launch golf balls 500 yards.
The NcStar Golf Ball Launcher can be affixed to any .223/5.56 rifle that uses a standard 1/2×28 thread pitch, which is pretty much the industry standard. In other words, if you have a threaded barrel on your AR-15 or other .223/5.56 rifle, you can use blank rounds to fling golf balls farther than any golfer with the pull of the trigger.
