    Obsidian 45

    Published by Unknown on 8th Dec 2023

    I bought this so I could use tapermounts with the obsidian 45. If fits perfectly and i can now mount the can up to anything with a tapermount. It's worth noting that having the griffin tool is helpful for getting it appropriately tight, or getting it off if it snugs up too much. It doesn't come with the tool. The slots almost look like a castle nut wrench would work, but it won't... it's not the right size.

    1st plain taper mount

    Published by Jake on 6th Jul 2023

    This is the first plain taper mount that I've used from Griffin and it worked spectacularly to make my Rugged Obsidian 45 faster to swap around on my BigBoyX 44 mag, Homesteader 9mm, and AR9 pistol.

    Plan A Taper Mount

    Works perfectly with my EZ Brake and Optimus for a compact configuration on my 9mm AR SBR. Fit and finish are great as usual with Griffin products.

    Perfect for optimus

    Published by Unknown on 7th Aug 2020

    Paired this with my optimus to replace the minimalist blast shield for a shorter package on a 300bo mk18.
    Would be nice if it threaded directly to the optimus rather than the booster housing but still looks and works great as is.

    Awesome on Optimus

    Fit and finish is nothing less than what you’d expect from Griffin.

    Plan A adapter

    Published by SGB on 29th Mar 2019

    Excellent component to allow use of the Optimus suppressor in short configuration (6.5" instead of 9.5") on AR platform and using Hornady Black 75gr InterLock HD SBR ammo that has no unburnt powder after 11.5" and no muzzle flash.
