Pics of the trade show A5 model with serial number 88-055885, have been confirmed as the data point of HAO’s new HK416A5 kit for Systema PTW.

The tone of this model is different from the service rifles which are seen in use with various militaries. The latter present with decidedly green receivers.

Model 88-055885, on the other hand, presents as a mix of browns.

Basing their A5 on 88-055885 and not a service rifle, HAO has prompted vigorous debate online; and I have been discussing the topic robustly with my friend Denis.

Some people prefer the original brown of 88-055885; others the green of the service rifle. Both palettes are termed “RAL8000” – rather confusingly.

Quite separately, there are a number of threads on the HKPro forum which discuss the variegated nature of RAL8000. So this isn’t a new discussion, or one limited to the milsim and impression community – it’s even a talking point in RS circles.

I believe this table is from one of the threads on HKPro:

Furthermore, it is my understanding that the table originated from this thread itself, but the pic links are no longer operational:


The OP of the thread states:

The table uses “brown” to denote the dark “chocolate” color first used when the HK416A5 began appearing a few years back…

The table uses “burnt bronze” (Cerakote H-148) to denote the somewhat lighter form of metalic brown that is common now on HK weapons, but is clearly not RAL8000 as seen on the pistol grip…

The table uses “green” to denote a similar form of metalic color, but one which is more green than brown. So far, I’ve only seen it on the HK416A5, and then, mostly on rails.

The table uses “RAL8000” (Cerakote H-8000) to denote the yellowish-brown color that is often described as similar to baby poop…Of course, this category by itself is quite broad on its own, as HK has been all over the yellowish-brown map with parts of late (stocks, grips, rail covers), sometimes even within the same part. Currently, RKS Plus is having a fire sale on mismatched SlimLine stocks…

So like I said, this table is just the start. To date, I haven’t really found any rhyme or reason between the various colors HK denotes as “RAL8000,” or even between the various shades within the yellow-brown of RAL8000 that HK uses for parts.

Within each category where more than one color appears, I have listed the most commor color first. As folks move beyond basic black to accessorize their weapons, hopefully some will find this table of use…

So that explanation, in conjunction with the table, clears up any outstanding niggles for me.

Also, it underlines that the green tone seen in the French, Irish and Portuguese A5 (for instance) is a later affectation than the burnt bronze and brown of model 88-055885.

I think I know which is prettier – and it’s not the green, as shown below:

It will be interesting to see what HAO’s A5 looks like in real life. My bet is it will look something like this (clue – it’s model 88-055885):

Now, onto a bumper crop of detailed pics from HAO and the most interesting thing for me is the device at the rear lug:

I think I am right in saying that this is sprung, and helps prevent wobble between the upper and lower receiver in the RS. The idea is, the upper will be more widely compatible with 3rd party lowers.

I would guess this feature isn’t required with HAO’s tolerances but it is a nice touch. It’s this kind of painstaking detail which has made HAO the market leader in PTW parts.

Enjoy the rest of the pics and as usual big thanks to Bismarck; and to Miguel for taking such great pics. Also a huge thanks to Bou Yan for the video.
