Also known as: MP5 Navy, MP5A5 SEF

Overview

The MP5A5 is the four-position-trigger-group, telescoping-stock variant of the iconic MP5 submachine gun, combining the collapsible stock of the A3 with a fire selector offering Safe / Semi / 3-Round Burst / Full-Auto. Built around H&K's signature roller-delayed blowback closed-bolt action, it remains one of the most accurate and controllable 9mm submachine guns ever produced and is the configuration most commonly chosen by tier-one military and law enforcement units.

Notes

Distinguished from the MP5A4 by its retractable steel stock; from the MP5A3 by its 'Navy' burst trigger group with the icons replacing the European S/E/F lettering.

Background

The 'Navy' designation for the burst trigger group dates to a 1980s US Navy SEAL contract that demanded pictographic icons in place of European lettering so soldiers could change selector positions in zero light by feel. The MP5 became the global symbol of 1980s-90s special operations after British SAS troopers stormed Iran's London embassy on live television in 1980.
