    This thing rocks

    Published by D on 24th Nov 2022

    Works great on rimfire. Also great on .223 with the taper mount adapter. Being able to run occasionally on center fire is a nice feature. Easy to disassemble for cleaning. Unless you absolutely need the smallest lightest rimfire can available, the Optimus micro is the one to get.

    Optimus Micro

    Published by LocoMike on 31st Aug 2021

    I wanted the sturdiness of a 556 that also performed well on 22LR. I researched, agonized and went back to verify my selection. Finally, after a 8 month wait I relieved my stamp and Optimus Micro. The performance and interchangeable mounting options have proven my time well spent. I’m always finding new applications and mount combos. Pistol, Rifle doesn’t matter it matches all my requirements.

    To the team at Griffin. Thank You and be aware we acknowledge that you invest in R&D more than marketing. Both this and my Revo-45 are constant companions to all my shooting sessions.

    Perfect for PS90 SBR

    Published by DoubleJ on 20th Jan 2021

    Nice and short in direct thread configuration on my PS90 SBR. Still shorter than a 10" AR with no can and hearing safe. Works well enough on 22s and surprisingly well on an 18" AR. Cleaning after 22LR use much easier than anticipated.

    Great for rimfire and .223/5.56 Nato.

    Published by Wayne Scholtes on 30th Nov 2019

    I have it set up with the taper mount adapters to run on all of my .22 caliber guns. The taper mounts add 4 ounces over direct thread on the rimfires. On the rimfires all you can hear is the action. Others on the range have told me that my AR15s are unusually subdued. No noticeable FRP with those or the centerfires. A quarter fits the outer cap slots perfectly and a nickel does the same for the inner cap.

    Optimus Micro

    Published by Adam on 9th Oct 2019

    After a year of waiting I finally got the suppressor.
    Originally intended to mount it to a 10/22 for the kids but it has also found a home on a .223 varmint gun with great results.

    my point of impact did shift but accuracy was fantastic. well built suppressor.

    Multi-Use Optimus Micro

    Published by Frank on 15th Jun 2019

    I bought this suppressor to have a rugged and long lasting solution for rimfire. I would be happy with just that, but this suppressor also works with 5.57 and 5.56 (or .223). It is a perfect solution for anyone that wants one suppressor that works with multiple firearms.

    Optimus Micro with taper mount adapter

    Published by William on 12th Apr 2019

    Silencer will work great with the direct thread adapter. For higher power loads ie 22-250 you will need a muzzle taper mount brake and taper mount interface. About $200 additional. Small size and solid. Quality.
