This guide details the disassembly and caliber conversion process for the Denel NTW 20 anti-materiel rifle, as demonstrated by Ian McCollum. It covers barrel removal, bolt swapping, and reassembly for multi-caliber capability. The process requires careful attention to the locking collar and bolt selection.

Quick Summary

The Denel NTW 20 is a multi-caliber anti-materiel rifle designed for man-portability. It can switch between 20x82mm and 14.5x114mm calibers by swapping the barrel and bolt. Its effectiveness stems from explosive 20mm rounds, and recoil is managed by a buffer, hydraulic dampener, and muzzle brake.

Frequently Asked Questions

What makes the Denel NTW 20 a multi-caliber rifle?

The Denel NTW 20 can be converted between calibers, primarily 20x82mm and 14.5x114mm, by swapping the barrel and bolt assembly. A single-shot variant also exists for the 20x110mm Hispano cartridge.

How does the Denel NTW 20 manage its significant recoil?

Recoil is managed by three main systems: a large spring-loaded buffer in the stock, a hydraulic dampener at the front of the receiver, and a massive muzzle brake. The barrel and receiver recoil together within the chassis.

What is the intended role of the Denel NTW 20 anti-materiel rifle?

Unlike older anti-tank rifles, the NTW 20 is designed to engage targets like light vehicles, radar stations, and heavy equipment using explosive 20mm rounds, rather than relying solely on kinetic energy for penetration.

What unique feature does the NTW 20's bolt action possess?

The NTW 20 features a unique primary extraction mechanism where the bolt handle pivots on a spring, providing significant leverage to help pry stuck cases out of the chamber before the bolt is fully cycled.
