    I don't know really, but I have a theory.
    I just want to clarify what kind of failures we are talking about here. Most of this thread when we talk about a failure it has to do with the weapon not cycling all the way or enough.

    I am very interested in what failures you and Grant have had due strictly to the bolt. Is it a failure to extract, or are you trying to blame a failure to not fully cycle on the bolt design?

    Thanks

    We aren't talking about shortstroking. Failures to eject, and extract.

    I personally wasn't given any problems with the Knights E3 bolt.

    Thomas-M4: I still don't understand it 100%, but I know what you mean a bit more. Thanks for the help.

    So Id like to add some info.

    Did some testing today with the LMT enhanced bolt and carrier in my SBR. 11.5 inch Noveske barrel, XM193 ammo, both suppressed and unsuppressed.

    It would not lock back on the last round regardless of suppressor usage. It also didnt matter if I used the ST-T2 buffer or the H-2. Cycled fine just wouldnt lock back the BCG on last round.

    Changed the entire BCG with a Young Manufacturing National Match, ran fine. Swapped the bolt out and put it in the LMT enhanced carrier, ran fine. Tried to use a brand new BCM bolt.....wouldnt fit in the carrier.


    Hmmmm, couldnt figure that one out.


    Used a Noveske bolt in the LMT carrier, ran fine....regardless of ammo, buffer, spring, suppressor.


    So its without a doubt the LMT Enhanced bolt that is the problem....at least with my gun.

    Was that with the switch block?

    This has been an interesting and informative thread. I've been making plans for an SBR some time next year that I could also run suppressed. It would be ran suppressed virtually 100% of the time, but I would prefer the rifle function without the suppressor just in case. I was leaning toward the DD Mk18 with a Vltor A5 RE system and an AAC M4-2000, but now it seems that may not be the best route to take.

    What part wouldn't work?

    I'm going with a Noveske Mk18 with Ranger 2 suppressor with a "suppressed only" gas block...which will put the gas pressure about what it would be on the Noveske switchblock turned to the "suppressed" setting. From what I read, the pressure that that would put out is STILL overgassed, and should cycle unsuppressed as well...I'll start out with a standard carrier, but it maybe could benefit from the LMT enhanced carrier...

    Based on what I'm reading, I don't think it wouldn't work. It just appears from Grant's experiences and trial and error that it may not be the most optimal setup for running suppressed. As I understand it the DD Mk18 is designed to run reliably unsuppressed, which would make it pretty overgassed when suppressed. The setup you described might be a little better in that it wouldn't be as overgassed as the DD option. I could be wrong though.

    Ok I see what you're saying now...my suggestion is to play around with different buffer weights as well as different springs, maybe some of the springco springs...

    Another option is to have two different spring/buffer combinations based on how you are shooting the gun. IE...for home defense where you will be using your suppressor and higher powered ammo, have a heavier spring/buffer installed. BUT when you know you'll be shooting Wolf or whatever underpowered ammo at a class, without a suppressor, you can install a lighter buffer/spring...

    That doesn't sound like a bad idea. I don't know if you noticed or not, but I edited my post above after you quoted it. I would almost certainly be putting a Vltor A5 system on whatever SBR I buy or build. Experimenting with the heavier A5 buffers would probably be a good idea as well.

    No, I didn't see it...I don't know much about the A5 though...I've heard both good and bad about it, but mostly good.
