    I have a Lesson Baer 6.5 Grendel 20inch barrel. I ordered your ultra 9. Will I need to install an adjustable gas block or will it function fine without a adjustable block? Can't wait to get my Ultra 9. It's been 4 months already. Thanks for your response

    Hi,

    It's hard to say, every upper is a little different. Try it without, and then only add one if you get problems
