    Need help identifying an AR-15 variant

    Sometime within the last few months, I read a magazine article on an AR-15 which had an interesting feature.

    It had its iron sights offset at about a 30-45 degree angle to the right of the receiver, leaving the top plane completely open for optics. For long-range shots, you could use a scope mounted on the flat top, close to the bore axis. For CQB, you just cant the gun a little and use the iron sights.

    Does anybody know who makes this?

    I read the write up on it in the April/May issue of On Target.
    I checked and that issue is not yet available on the internet--maybe next month--but check in anyway, register, and get in on the giveaway.

    That's a different take. The 3 gunners and hotshots have been using flat tops with BUIS and an off-set micro sight, ala JPoint. I'd have to ponder on off-set irons.... switching over to a holo sight doesn't require alignment, irons do. Maybe I'm just not that whippy, but initially I'm not too wild about the concept.

    Edit: Don't like it. The iron front is bulk hanging out to hang up, even folded. An off-set JPoint is at the rear of the HG. You might crush it, falling on your rifle, but you won't snag the whole works shoving your muzzle through an aperture.

    Thanks, Ram Rod! Come to think of it, that's probably where I saw it, too.

    It's just a shame that Sabre is so PROUD of their rifle. I notice that the upper has the very same MSRP as the whole rifle.....

    I liked the basic concept, though I'd want a longer sight radius. For whatever reason, I had thought that the rear sight was at the rear of the receiver.

    Now I'm wondering if I could just get a pin-on front sight assembly, a flat-top gas block, and an off-set flip-up rear sight.....

    I hadn't really thought of it but DPMS makes a 6 rail forearm and their mangonel sights seem low profile... I wonder if you could make that work for much less $$$.

    Not sure, but i have these on my 3 gun rifle: JP Rifles They are called the "JP Short-Range Tactical Sight" and the concept is the same, the sight is more similar to a pistol sight though. I like these more than the other ones because these are a little quicker to get on target with at the distances that I am going to be using them for. I have them at about 40 degrees off the right side of my handguard so that all I have to do is roll the rifle a little to get those closer shots. You can see it towards the barrel end in the attached pic.

    Hope this helps!

    With an aluminum free float handguard--all you'd need to do is drill and mount a rail in the right place and put your flip up sights on there. I used to have a GG&G mount for my M-3 tac light mounted at 45 on the left side of my M4 carbine plastic handguards. I'm sure you could find a more cost effective way of doing this than buying that upper.

    This is a picatiny offset 45 degrees that might do the trick. There are longer versions available

    You might want to take a look at the Viking Tactics free float tubes. They are pretty much exactly what you're describing - and if you don't want to spend $2k on the upper, you could always do even better and get yourself the Noveske/Viking Tactics upper - check it out at Noveske Rifleworks, LLC. Precision Battle Weapons. NoveskeRifleworks.com - click on the Products link and then go down to the bottom and click Viking Tactics.

    If you have to rotate the rifle to use the BUIS then the ejection port will be facing straight up, or close to it, unless I am misunderstanding how this works? Not sure I like the idea of rotating the rifle in order to use the BUIS.

    It's for speed.

    Scenario 1:

    Optics with BUIS
    Long range shots transition to short range shots, you need to detach the optics or you slow down a lot.

    Scenario 2:

    Optics with offset BUIS
    Long range shots transition to short range shots you only twist the rifle without losing your grip or position.

    What's wrong with the ejection port facing up? The brass isn't going to fall back into the gun. These things are marketed towards people that want a variable power scope for medium and long range shots, but still want the ability to shoot fast at short range.

    Even if it DID, by the time it got back there, the bolt carrier would be in its way.
