***Beeman has used two different barrel threads on the Underlever family of PCPs, and to get the right adapter you need to know how your barrel is threaded. You can choose between 1/2×20 or M12x1.25 threads depending on what threads your airgun has.***

    The Commodore comes with a totally plastic shroud system that really sucks at keeping the noise down. This adapter from Buck -Rail is very well built from quality material and it fits absolutely perfectly more than that... Adding the Donny FL Sumo moderator makes this gun backyard friendly. At first I couldn't hear the pa-ting on my targets now it's very definitive. I don't have a decibel meter but it really made a difference! Excellent product 5*

    Fits great, and the supressor went on easy, significant noise reduction, and even my mom, a 64 year old grandma, said it "looked bad ass"

    I'm waiting for the Suppressor I ordered to come next;
    this gun was pretty loud before changing this adaptor...
    Now it's off the charts loud... Wow
    This adapter is a beautiful piece, it was very easy to install, it is well designed and built...
    I tried to order both the suppressors; I only could get one, I can't wait to hear, the difference

    Fits like factory
    This is the only way to add threads to the barrel. Screw the non threaded one out, and this one in. Perfect.

    Before purchasing the DonnyFL adapter for my .177 Beeman Under Lever pcp bullpup I purchased the Buck Rail adapter. With the Buck Rail adapter which includes a built in suppressor my Beeman UL wasn't much quieter than without the adapter so when I was notified by Buck Rail that they had the DonnyFL adapter I had to give it a try and I also ordered a Buck Rail suppressor to go with the DonnyFL and it was a little quieter but not much. My plan is to get a DonnyFL suppressor next to see if that makes a difference. Regarding the adapter, the fit and finish is perfect but so is the cheaper Buck Rail adapter so based on my experience I'd pass on the DonnyFL unless you wanted an adapter that allowed the removal of the suppressor.
