They both have some familiar appearance, the XCR looks less... rough... Anyway, the XCR seem to blend many other rifle's assets, maybe the hac7 is one of the exemples Robarm used as bases to create their gun.

However it brings thoughts of a future .308 XCR :cool:
 
Hey Tony, looks pretty interesting to me too. I never even heard of the HAC7 before this and I have been around firearms for over 50 years. Mind you I haven't delved into obscure stuff. G&A is great about answering queries such as this.

They have been good to me in the past. I'll write and see what they have to say. If there are any particular questions you want me to ask, feel free to PM me.

Assyrian, I wonder how many times Winchester, Sam Colt, Ruger, Smith and Wesson to name a few, tried and failed then yet prevailed. Give your head a shake. This site is to promote and deliver knowledge, not derision.

Looks like the patent is expired. This might be an interesting project...

I would love to start producing them but good luck finding blueprints... you'd have to spend some time in the US to find a rifle to base prints on and even then, those HAC-7s are few and far between.

Yawn.
What happened?? Some guy tried to make his own rifle and failed. End of story.
Not forgotten. No one cares.

yup, you're right, they are both black. Could be one and the same???????

You obviously don't know much about the rifle.

You would be further ahead just designing a new rifle to make use of modern manufacturing techniques and all that new stuff.

True

After looking at the locking mechanism I've gotta say I like the design. This is probably the simplest rotating bolt head design I've ever seen. Hmmm All that's missing is dimensions.... but I can make those up myself :D
 
I have heard the same thing. Did not the Australian Leader also have problems? If you study the evolution of most any design, there is a developmental curve before the bugs are worked out. This takes time and money, sometimes a lot of time and money. Its not enough to have a one-off prototype that works some of the time. The design has to be one that can actually be manufactured, with production versions that do not need adjustment and tuning before they work well enough to actually sell.
 
I also have a few articles on the rifle - and there's nothing unusual or ground-breaking about the design. Blended are an FAL gas system, AR rotating bolt into a barrel extension - but 3 lugs for simplicity - and Galil folder. Soon as I get some more time, I'll draw it up in Solidworks. The Australian Leader was a poorly-done AR-180 copy - it also failed due to poor sales and bugs...

I agree, blueprints are probably very difficult to find but the details in the patent could be a good roadmap.

Take the good parts and combine them with your current project.
