    So I've been reading and apparently my 7.62 SCAR-H SD will work well on 5.56 (well enough to try it out that is - I've heard a couple of folks talk about pretty good results online).

    Problem is that there's only one 51 tooth MITER connector for 5.56 barrels and its made for the SPR/M4.

    Now the 7.62 version is offered in only one barrel-thread option:
    5/8-24 TPI (for the AR-10).

    But the 5.56 version is offered in only one barrel-thread option as well:
    1/2-28 TPI (standard AR-15).

    Here's my question - will my 7.62 SCAR-H SD screw onto a 5.56 MITER flash-hider, or will I have to butcher up an AR barrel in order to get a 7.62 MITER connector on it (in a thread-pattern that I won't use with anything else ever and is really just to try this out)?

    I've only got one 16" barrel and I'm not looking to screw it up, so any help is definitely appreciated at this point - I'm willing to go out and pick up a 16" barrel to make this work (and chop it down to a 14.5" after I'm done) so that I don't have to screw up an existing nice barrel.

    found this:
    Incorporates the M.I.T.E.R. System™ for use with the SPR/M4™ and SCAR-H SD™ silencers.

    So, it should work. The YHM Phtm QD's are the same thread for 7.62 & 5.56. The 7.62 flash hider is longer so you are able to mount a 7.62 can on a 5.56 rifle but not the other way around. So, even though the threads are the same, the length of the flash hider prevents the 5.56 can from engaging the threads on the 7.62 flash hider. The AAC MITER system probably works on the same principle. My buddy just bought an AAC SPR/M4 from Maj. Malfunction the other day & bought 3 mounts with it. Bryon sells the mounts for $125.

    The SPR/M4 51 tooth mount WON'T work with the SCAR-H (and visa-versa).

    The bearing surfaces are different. :(

    That brings the total to about $200 to try it out (and I've got an extra MITER QD out of it to use later)...

    I'm trying to find a reason not to do it, but that's pretty darn tempting.

    Bryon, I hope you ordered more than one of those when I bought the last one :D I may be hitting you up again.

    TROS makes those adapters and he is a BAMF. I got the link from Silencer Talk when others were having the same problem you got.

    Appreciate the info man - I may have to pay for a subscription over there. I keep wanting info on how their silencer shoot-outs go and hearing stuff second hand probably isn't the best way to go about that.
