The Firearm Blog

This video shows Groot Mamba, a reader of the blog, rapidly firing the NTW 20mm rifle. Groot is firing the 20X82mm round, which is, in a sense, a "20mm Short" round. When firing a projectile that can carry a high explosive warhead, kinetic energy is not necessarily required against soft targets because energy can be delivered with the chemical payload - hence the lower powered cartridge.

Groot says that the larger, and more common, 20x110mm round is nicer to fire because the muzzle brake is more effective.

I love this photo.

20mm Lahti rifle vs. PKM machine gun

Many thanks to Sven for sending me the link.

If the suave gentlemen in the above photo had a beautiful woman beside him, I think the scene could hardly be distinguished from a Bond movie. Style, sophistication and an incredible amount of high explosive firepower!

The side mounted pistol grip makes this a very compact weapon for its class.

Quite frankly, this is an awesome piece of hardware. I can't say much else than that. I hope to be writing more about this weapon in the near future.

A big thanks to Groot Mamba for the photos.
