MDT Builds World's Longest Rifle To Find Out How Long Is Too Long

A couple of months ago, we took a look at an amazing MDT project where they made the world’s tallest scope base that resulted in 20″ scope height over bore, to find out if scope height matters for long-distance shooting. Today, we have another mind-blowing MDT project. The company’s engineers built a bolt action rifle with a six-foot long barrel to see what effect barrel length has on the projectile’s velocity for a given cartridge (.308 Win in this case) by gradually cutting the barrel down. Who makes six-foot long barrel blanks? Nobody, the barrel of this experimental rifle was made by screwing together two barrels! MDT claim that with an overall length of 88 inches, their project gun is the world’s longest rifle.
