I was clearly looking at the 5.45 variant but it seems that the link is for 5.56 now and furthermore I cant find any offering in 5.45. But, on HKpro ( where I got wind) they have a thread confirming such thing.
In any case, my deepest apologies for the misleading info.
That's interesting. Will keep an eye on that for sure. Glad to see a company focusing on other HK platforms besides the G3/91 and MP5. The HK33 has to be one of my favorites.
