    LUCK
    is the residue leftover when you subtract chance from preparation.



    If you reload, turn a flat based bullet around and seat it backwards in the case with apx .170 of the full dia part of the bullet left outside the case. Chamber it. If it chambers you have a SPCII. If not start seating the bullet deeper. If the full diameter part of the bullets ends up apx .070 out it is a SAAMI chamber.

    No in my opinion as stated above the adjustable gas blocks work!

I also was able to get 3:00 ejection with my 8" barrel but had to install an H2 buffer with that short gas system to obtain it. From what I understand they work really well in 5.56 applications but I don't know that from experience.

    The SLR and the Odin are the best restricting blocks IMO as well.

    For now I'm satisfied with my Superlative blocks.
    No matter how much I changed adjustment they ejected at 3 o clock. Didn't mean they fully cycled, cycled harshly or work properly.

    I'm not bad mouthing the product as the product itself is a good design but they just didn't work well with the gas pulse of the 6.8.

    Agree, the blocks are machined very well and are done right. The first blocks I had would have been just fine if I used them as a conventional gas block and restricted the gas, they just wouldn't work as designed. Now that the bleed off port was increased and set at full bleed off suppressed, the ejection is back to 3:00 which I can live with.

    Like I said they always ejected at 3 o clock didn't make any difference the gas was all over the place and wrong. It made for inconsistency and therefore hurt accuracy. Or I'd be using them.

    You can't just go off where the brass lands especially in a venting type system like this.

    Mine were 1-2:00 b4, consistent @ 3:00 now. 90 gold dots suppressed shoot great @ 100 yards which I'm satisfied with for deer hunting here in the hardwoods. If I was to shoot heavier Bullets or hotter I'd be back to over gassed again and be forced to restrict rather than bleed off.

    So Brett, once SB 710 passes and CA can put a suppressor on hunting rifles, what would you recommend for an adjustable gasblock for a 6.8?

    I have no issues with the SLR adjustable gas blocks on my 6.8's shooting suppressed.

    I have a Superlative as well and could not get it to work as advertised on my 10.5" 5.56.

    He's using SLR's now instead of Syrac.

    Sorry missed this. Yes I recommend the SLRs that's what we are using now for all our adjustable uppers. Well designed and easily cleanable and rebuildable. I've always been a proponent of the clickable repeatable adjustments also.
