[AGR416]

As I have mentioned in a previous thread, the HK416N has been upgraded to ensure higher reliability.

The issues that have arisen are:

-Adjustable Gas Regulator popping out, or wiggling to Suppressed setting during firing. It is a maintenance issue, but disassembly of the AGR is as of now not part of 1st line maintenance.

-Disconnector breaking. At first thought to be due to poor materials used by HK during manufacturing, turned out to be a result of the environmental ammo being "hotter", causing more strain on the disconnector when the hammer struck it during cycling of the bolt. Mostly an issue on the 10.5" HK416K.

-Wrong dimensions on roll pins. Mostly an issue on the charging handle and buffer, although there has been one incident where the ejector assembly roll pin was pushed out during firing. It finally protruded so far out of the hole to cause an out of battery incident, with the gun blowing up. Thankfully only minor injuries to the shooter.

The modifications done to my gun are:

-New AGR, with new pin and spring assembly. It will not come loose anymore due to carbon build up, and is much easier to clean. No disassembly needed. It also has bigger ports, allowing for increased gas flow.
-New trigger assembly group. Two stage trigger, same as on the HK416S, and a hood protecting the disconnector from wear
-New roll pins on charging handle
-New ejector roll pin
-Staking of the roll pin in the buffer

I haven't been able to shoot it yet, so cannot comment on the effects of the new trigger, or if the bigger holes in the AGR smooths out the action at all.

Nice stick dude. Looks......"salty".... ;-)

Any reason for not removing the paint from deployment?

Because I'm lazy....:wink:

To be serious, it provides some heat protection and camouflage properties, so I decided to keep it. The area I'm stationed isn't a very lush and green area, so the color scheme it has now works quite well. Even in winter. Nothing sticks out more than a black rifle.

You need an enhanced trigger guard...very nice

I need it? What is your reasoning for saying that?

The soldiers in my battalion show up for basic in january, so we use big ass mittens when we practice weapons manipulation, without dropping down the trigger guard. For people who are having trouble, we can just press the pin and drop it down for easier access.

So who do I blow to get one of those old style removed AGRs (with front sight post)? ;-)
