    I don't know for a fact as all my HALOs are the older generation, but I thought that was the stated purpose of the second generation (current), to work with extended flash hiders like Predators.

    The peel washer is simply to keep the flash hider level and true and prevent baffle strikes. Crush washers can cause flash hider tilt.

    It's my understanding both old and new work with extended a2s etc. I have one just before they "lightened" them and it fits on extended a2s. I confirmed with gemtech and they said as long as you get several turns on the hider you are good, it just won't screw down as far as a standard length a2.

    I keep looking at the Halo in the case of my LGS...I may have to get finger printed.

    The only carbon welded halo that I have seen was on arfcom. Somebody posted pics of a halo that had thousands of rounds through it with ever being removed. IIRC they had to pull the barrel from the upper and then strap it down to get it off...if I also remember the baffle looked ok...

    Back to the ops question, as long as you line the collar up near the same every time your poi shift should be repeatable. I wouldn't buy a halo to put a precision rig, I use mine on my 10.5 and 14.5 uppers.

    I know the older model installs on a HK 33/93 and I think that is longer than any A2.



    I know they fit on my A2 HBar.

    We have a whole new GEN of shooter who don't clean barrels.

    The 2010 models and up can use the Vortex FH. I time mine using the FH tines. Same POA/POI everytime, 100-300 yds confirmed. I also use a BC 2.0 and as long as the can stays centered at the same o'clock it maintains POA/POI. Recently went to a shoot and had AAC, YHM and OPS Inc 5.56 cans, couldn't tell a difference between any of them except for the OPS Inc (M4S can). My collar has never had a problem loosening or having to get it off after I needed it to. As always, YMMV.

    Forgot about the whole Vortex thing. My model DOES work with extended A2s but will NOT work with the Vortex...

    Speaking of the Vortex, anyone know the difference between the A3 and A2 as listed on Smith's website? http://www.smithenterprise.com/products06.05.html

    Other than the obvious fluting, that is. Does the 10 degree pitch refer to the prongs (meaning they are not 15 degrees like a standard Vortex)? I've also read about some "super alloy" in the A3s, but that isn't listed anywhere. Finally, does anyone know if the flutes actually help with anything on the HALO?

    I ask because I'm looking at pairing my potential HALO with the A3, should everything line up correctly.

    Not sure on the A2/A3 I'd call. But the tines allow you to clock the HALO and always have the same lock up.
