The G36A3 is an interesting evolution in the G36 series of rifles. The redesign attempts to mitigate the transfer of heat from the trunnion to the nylon receiver. The issue being addressed stems from accuracy concerns when the guns are used in a light machine gun role. The design incorporates a perforated heatsink mounted to the barrel in front of the barrel nut. The traditional front sight post is completely removed. The nylon shielding surrounding the barrel nut has been removed. And, the rear top rail mounting hole has been removed. It is a clever design. I just like the color of the mag.

It looks very 243ish..that one piece rail system is cool but ill bet the gun is now heavier.

I wish I could see the heatsink without the hg installed. The drawings dont dont do it justice.

I think removing the front rail mount opens up a lot of design options.

TY I was looking at it after my post....yes you are the best 👍
 
Interesting--- was it Steyr that figured out the overheating, plastic problem? :unsure:

@Nzfly I wonder why they went the heatsink route rather than something more like the PKP which is a forced convection based system.

I do love that they haven't given up on the G36 tho

IDK if I would even call it a problem. It works within its designed parameters. I often cut food with the edge of my fork. A fork isn't a knife although it can be used as one, but at a certain point it fails as a makeshift knife.

The PKP falls outside of my tiny bubble so I am not familiar. This redesign appears to have been a way of resolving bureaucratic objections without having to completely replace entire inventories.

Yeah the PKP is ingenious IMHO.

This A3 variant solves 2 issues for HK I.e. fix the "perceived" issue and add $$ to the HK coffers for parts and possible refurbishment while the rifles undergo retrofit while not having to tool up for a whole new rifle or production line.

To quote an old Gieco commercial, "it's so simple a caveman could do it", whack off the front post and add a heatsink to the barrel then reinforce the reciever with a slip on aluminium shell.

Crazy simple retrofit with minimal parts.
 
This is actually the HK233. The G36 A3 (and A4) are drop in parts upgrades for the G36 used by some German Army units and mostly for export. These include aluminum handguards (that approximate the shape of the old polymer handgaurds) that allow Pic rails to be installed, or handgaurds that look kind of like the early HKey SA80 handgaurds, the IDZ/KSK stock, and standardizing on the top mounted Pic rail with iron sights instead of the old carrying handled with integrated optic.

Here's what they look like:

Also, HK claim that the photos of the G36 on their worldwide site is of the A11 variant, which has the metal handgaurd I first described that the Pic rails can be screwed into.
 
HK has so many stupid designations for the series it is nearly impossible to capture all of them, so A3 may not be correct. That said, it isn't a 233. The 233 is a completely molded receiver. My picture is of a retrofit. It is a standard G36 receiver that they cut up and added the aluminum handguard and top rail. HK's website does not show this version. It shows the monolitic receiver with these features.HK233_re.png
 
The IDZ Convex is so damn sexy. And yes I waited for one for over a year from those scammers (damn happy I did too 😁 )
 
Here is the precursor to the IDZ. This version housed a battery and computer board.

I found the IDZ concave stock too short fully extended and went back to the full size ral8k one. I think they are made for plate armor use
 
These pics are from a pro thread where SMGLee took pics at an Association of United States Army expo. The pics show the early version of the IDZ program. The battery and mother board were stored in the stock. Note how the rear of the stock hinge extends higher than the line of the receiver, there is an additional hinge bearing. This was to allow the wiring to pass through and be routed throughout the gun via the top rail. The system integrated Push To Talk buttons on the handguard as well on the sides of the magwell forward of the selector switch.

I thought the electronics were for remote transporter control and cloaking device activation on this star trek worthy rifle 😂
