Today I've got on of Gorilla Ammo's GF-10 rifles to do some shooting with. It's an AR-10 platform chambered for 8.6mm Blackout (they also offer it in .243 Win, .260 Rem, 6.5CM, and .308 Win).

It's still a heck of a gun, weighing in at about ...

Replacing Beretta: the S&W XM10 Trial...
When the US adopted the Beretta Model 92 as the new M9 standard issue handgun in 1985, it was not without controversy. In particular, there was a scandal of cracked and broken M9 slides shortly after procurement began. The military did not budge on awarding the M9 contract to Beretta, but in 1987...

The Gun Science Says Can't Work: Mads...
The Madsen LMG is generally considered an extremely complex and confusing system - but is it really? Today we are taking one apart to see just how it actually works. Because in fact, it's a very unusual system, but not really any more complicated than any other easy self-loading action.
