We have all heard the reports of those rifles failing during combat during Vietnam and even yet today. During the 60’s when it was first introduced, it was hailed as “the self-cleaning rifle.” Of course that was proven to be a myth within the first months of its service. Soon thereafter, cleaning kits, cleaning manuals with attractive cartoon-like characters, and muzzle covers were issued in large numbers. A lot of the first problems the rifle saw were due to using ball powder vs. stick powder. Ball powder burns hotter, faster and dirtier than stick does. This caused the rifle to gum up quicker in the humid atmosphere of Vietnam and mis-feed the rounds. The U.S. Military then switched back to the cleaner burning stick powder and added a forward assist to jam the bolt carrier forward after heat expansion and carbon build-up. The military saw this problem and fixed it fairly early on, so why haven’t they saw the clear flaw in the 100% gas-blowback operation of the firearm? Why haven’t they learned lessons from rifles such as the AK-47, AK-74, G36, SCAR and countless other who have switched to a short stroke gas piston?

So far rifles such as the HK 416, HK 417, SCAR and MAGPUL Masada have all incorporated this short stroke gas piston in their designs and have all seen massive reductions in carbon build-up, over-heating, and mis-feeds. If this needs any explaining; what this basically does is stop the hot, carbon-filled gasses just rear of the front sight and pushes a pistol-like rod back instead of the gas traveling all the way back to the bolt carrier assembly. It is even possible to convert current uppers to this gas piston system using such kits as those offered by Bushmaster. If the cost benefit is too great for these kits to be installed, why not begin to install them on the floor as they are now? They are 100% compatible with all lowers used by the M-16 and M-4.

So in conclusion, the main flaws of the M-16/M-4 assault rifle system is not necessarily in the round itself, but in one minor design feature of just the upper. This article is meant as a predecessor to a piece in the making on the advantages to switching to a round such as the 6.8 SPC or 6.5 Grendel. The 5.56 round is effective, but could be better. I want to hear your feedback. Tell me why so many people (mostly civilians) think the flaws of the rifle are in the round. I’m looking to you military folks; tell me about your operational experience with it. Airsoft players, armchair generals, and firearm enthusiasts; let’s hear your voice, but don’t comment on its “knock-down power” unless you hunt big game with a .223 or were once in the military and have used it in combat. Next up: A viable future replacement for the 5.56 and the M-16/M-4 combat rifles along with first-hand news from the front on forces already making the switch.
