    Somebody is using a TD lookalike grip. Not an intellectual property complaint, it’s a copy of a previous Stoner design, too.

    Billet does point out that not having a platter forger in Europe to buy from means it’s no choice but to CNC machine in full. With that extra cost, and the exchange rate, most of us won’t ever actually handle one. I speculate the cost to be above Colt retail, $1,200 or more.

    Makes the question of drop in pin on interchangebility mostly moot, unless they can competitively offer stripped lowers and finished uppers at good prices. Otherwise, I suspect they’ll be as rare as HK416’s.

    Makes me wonder what foreign military contract they’re competing for, it takes something with volume to set up production and underwrite the cost, pure speculation selling the American market (on the wrong side of exchange rate and importation difficulties) isn’t a good profit motivator.

    “StG4” – something to curdle a CA political appointee’s morning cereal? Why not?

  • Dillankid

    Where can you get that stock? I can’t find it on Google (SWT BCS Battle Collapsible Stock)?

    It looks to be set up like a CTR…

  • Dillankid

    Found it (on an Italian site):

    Judging by the price (plus shipping if I can’t find it in the states), I’ll stick with Magpul.

  • -dsr-

    “Guernica” is a really poor choice of names. The bombing of the Basque town of Guernica is more or less synonymous with terror bombing, the practice of killing civilians to inflict terror rather than going after industry or troops.

    Can you imagine Remington coming out with a rifle called the “My Lai” or Mitsubishi making a “Nanking” pistol?

  • Moreandfaster

    Anyone else think that Magpul might be a little queasy about those butt-stocks?

  • drewogatory

    Match chambers on a carbine? That’s just annoying. I got a killer deal on a Ruger Mini 14 Target, but it languished in the safe for years because of this very issue until I decided to get it cut, crowned and rechambered in Wylde.. Who wants to feed a carbine Gold Medal all day?

  • snmp

    hop for us that’s better quality that they sold in Europe (France & Swiss). for many peapole a Norinco M4 are better and far cheaper. For same price you could found AR15 from Oblerland, and many other brand or a SIG 550.

    Astra is spanish basque brand name own by italian compagy and may be build in Swiss with many sound who speak about asian cheap parts (china, vietnam …)

    You could found some of their weapons the mispeling of the name of the country in latin (like you could found in cheap fake of swiss watch)

    Right speling in latin : “Confoederatio Helvetica”
    Astra mispleing of name of the country : “Confederatio Helvetica” with an “o”

  • That stock looks a “little” like Magpuls CTR =)

  • Joel

    That has got to be one of the uglier ARs on the market.

  • Moose

    “Flat Dark Heart”. Hmm. . . That sounds absolutely badass and something I would want on my gun, but unfortunately, is most likely a typo.

  • Other Steve

    So, for what I expect to be a LOT of money… You get…

    A presumably accurate 223 barrel and a non-free floated (ugly) quad rail. This immediately makes no sense. Let alone that these barrels are M4 (retarded) contour. I would rather a 556 chamber with med chamber and a free floated rail. Especially a 556 chamber on the 10.5″ gun.

    Except for the Swiss logo, that billet upper is hideous. You can always tell that an mfg is only knows basic 3D modeling by looking at the forward assist. Very ugly. Learn to surface.

    You get a knockoff MOE stock, questionable iron sights, an 80’s grip (does anyone’s hand have cuts in it to fit those lateral ribs?), etc.

    Maybe I’m AR jaded, but I just don’t get what this does any better than the $600 S&W M&P Sport. Except that it’s uglier and harder to sell.

  • Clodboy

    Guernica… really?
    Maybe it’s just me, but attaching the name of a city most people associate with what is probably the most famous anti-war-painting in the history of art (not to mention the indiscriminate bombing of the aforementioned city which inspired it) to a gun might not be the best idea from a marketing standpoint.

  • Bandito762

    wow, that is ugly. That being said, I wonder how it shoots.

  • Adam B

    I love the knockoff MAGPUL furniture, VLTOR front sight and Upper Receiver, and Troy Rail System.

    Hallmarks of an innovative company.

  • Burst

    If you’re gonna color the grip, you oughta color the handguard- it’s just good taste. No amount of rails can hide it.

    Alternately, black goes with everything.

  • J.T.

    I have a feeling that there are going to be issues with that stock on the U.S. market. Mostly due to the fact that it is a ripoff of the Magpul CTR which is covered by at least one patent.

  • Nadnerbus

    .223 match chamber? People really going to be shooting matches with these, or wouldn’t a 5.56 chamber be a more versatile option?

  • Francis X.

    My intuition tells me this is aimed at customers who want to be able to say they own a ‘Swiss’ AR. There’s Swiss crosses all over it, the design emphasizes style over function, and it appears to be trying to be different for the sake of being different.

  • crisara722

    for my taste ths is the best looking AR in the market

  • hartzpad

    It’s named Guernica after the Basque city that was bombed because Astra is a Basque firearms firm. Astra is based out of the Basque city of Eibar and Guernica has been the revered “capitol” of Basque Country for hundreds of years, thus why Franco bombed it with the Nazis to send a message to the “rebel” Basques. It is named in remembrance of Guernica. Just like the Magpul Masada. It would be like a U.S. firm calling a rifle “The Alamo” or “Pearl Harbor.”

    I lived in Basque County for several years.

  • Axel Nordberg

    This must be rifled to some kind of competitive shooter/ wannabe warrior hybrid customer. I kind of think it looks cool with the g36 contour on the trigger guard and mag well.

  • Nater

    I can’t believe the .223 chambering (unless it’s a typo) and the fake KAC NT4 suppressor is hilarious. Who would buy a rifle with a fake suppressor? I can somewhat understand the fake suppressor if it’s to get the barrel length up non-NFA legality and even then it’s still very cheesy. Oh, and they obviously didn’t get the memo on the mid-length gas system. For that matter, neither did Sig. They probably should have copied LWRC one for one.

  • Peter BE

    The original company Astra Unceta y Cía was located in Guernica, I doubt they are referring at the destruction of that city in WWII…

  • April Daniels

    Am I the only one who thinks the fake suppressor is kind of silly?

  • slak

    I agree with the 2 people who already stated this:

    Guernica is a bad name at best and sadistic at worst. I own a firearm and it will be unfortunate if I ever have to use it. Celebrating gun culture is one thing I dislike. Patronizing a painting which illustrated the true horrors of warfare is completely out of line.

  • Nater

    April: Nope, I think it’s ridiculous too.

    -Ummm, I have a IP complaint. The StG4 grip violates a US Patent for the plug design and violates a US Trademark for the name ..Battle Grip.
    They have also violated trade dress on the upper.. a blatant copy of the Vltor MUR, and copied Vltor’s gas block as well. Magpul stock too.


    Needless to say, it won’t make it past US shores.

  • I love those Magpul CRT stocks! Nice weapons no doubt!

  • Tapsa

    On intellectual property rigths: They apply and are in force ONLY in those countries where the original owner has applied for them. Because the applications tend to cost quite a lot, most companies do not bother to register their design, brand names or even patents in all countires. Ever heard of patent in Ugand or Belize ?

    And if some US patents are not applied for in Switzerland they are free game. Same goes for Swiss patents not applied in the USA. CCF uses this method in selling “Swiss patented” B&T suppressor copies without any licensing fees whatsoever to B&T. It is a rip-off but totally legal.

    I believe these rifles will disappear from the radar pretty soon. Market in Europe is too small and competed and these rifles can not be exported to the USA.

  • Frank

    I found an “ASTRA” pistol. Marked “Unceta y Corpania S.A.-Guernica”
    “ASTRA-Cal 6.35 .25” “Made in Spain” Anyone have info on the firearm, especially how to disassemble for cleaning.
