my homemade .308 AR - only technical discussion please

[freeminder]

Hello

 

I want only a technical discussion please.

Nothing about laws, governments, etc... It should become a interesting thread for all homemade AR´s

 

Here are the first pictures of my .308 AR.

 

 

All parts are selfmade.

  Is this a complete & functioning rifle ?  Looks like FAL Gas Piston assembly .

[MikedaddyH]

Those technicaly are not pictures !

Do you have photos of this gun ??

Or is it just a dream ??? I am trying not to be a smart ass ,but I have those diagrams on one of my computers !

It looks like a replica to Adams Arms short stroke piston system. Complete with their switch block.

That design (I own one) has a lot of gas bleed off and isn't very economic. The HK system is a far superior short stroke, as it auto regulates gas flow. The former design also relies to heavily on piston rod alignment and spacing. HK's design autocorrects any alignment shifts. The HK design also has a replaceable piston cup, which it where all the wear is on that system.

Original post says all parts are self-made.  Does that mean you created them based on these drawings?  Still would like actual photos if that is true.  Hell, I'd like a couple of shots of your shop.  I assume "all" would include barrel, bolt, etc.etc.  Pics, please, and a clarification.

Why? Is it illegal in your country of residence? 

Only reason we had asked is outta curiosity, we are 99.999999% Americans here so we just wanted to learn more about how the rest of the world works seeing how the scoff at our "lacks" gun laws

I got a better look at the design (now that I'm not trying to look at it from my phone). I recant my statement about it looking like a AA system. It's nothing similar.

 Looks just like an FAL's with out the sight 

  What is the poster asking for again ?

Well damn. It doesn't get any closer than that.

I think Imschur has a 308AR that uses the FAL mags... or maybe it was G3 mags...

RRA LAR-8s use FAL mags.

You aren't thinking of those old CMMG 308ARs that use G3 mags are you?

Almost sounds like this and the thread wanting magazine blueprints is a phishing attempt........convince us otherwise.

  See how he gets when you mention that four letter manufacturer !  

 

I have a new fondness for my **** Lower ( didn't want to mention the four letters , don't want to upset him more ), its working pretty good now that Magpul came out with the Gen.3 Mags .

Wow!  MagPul mags are so good they even make ASSS (new 4-letter abbreviation) rifles work! 

[Robocop1051]

I have to give **** credit, they are trying really hard to get it right. They have put forth a big effort to change people's perception of them.

Why would this be a phishing attempt?  I'm not trying to argue, just kind of confused as to what there is to gain from lying about having a rifle build or asking for magazine blueprints.

There has been some anti-gun people going on gun forums and trying to "expose" illegal activity. There are regulations with big grey areas when it comes to exporting weapon technology. Blueprints and such could be considered technology. It would be just like selling your Nightforce scope to someone overseas, a federal offense.

[Robocop1051]

A lot of American websites are blocked in other countries. Unless they learn how to access the dark Web (and navigate it) most of out info is unobtainable for them.

Our 1st ammendment grants us access to a pretty liberal amount of access to information.

Now it makes more sense.  It's much appreciated.  Crappy of them to do that, but makes sense.

And still no pics from freeminder.......  why am I not surprised?  Sounds like JT's BS call was right on the mark.

[blue109]

The internet is much slower in Europe...

[EngrBob]

Wonder how fast it is in the Middle East, specifically Syria?

[EasyEJL]

I don't like that charging handle idea. seems to go a bit far forward in the upper, and i'm not at all a fan of reciprocating ones either in an ARish rifle :)
