    Just received the barrel band and uni adapter and suppressor. Very easy install, and nice fit. Shot several rounds through it without any clipping. There is a reduction in sound. Extremely satisfied with products.

    Have the new .25 regulated. It has a pretty good bark. The baffle and stripper are better than the factory, looks and sound. Put the non tapered one on and quieted it up enough to be back yard friendly. Thanks for making a good affordable moderator.

    Buck rail has went above and beyond the call of duty. Their products perform exactly, if not better than advertised. I had a small issue of my own fault and buck rail came to the rescue. If you don't send your business their direction.... You are missing out or not only superb equipment, but superb service.

    My 1357 was LOUD. The larger UNI suppressor makes it mouse fart quiet. I was truly amazed at how well it worked. As others have said, fantastic customer service. I broke my first one entirely through a fault of my own and was sent a complimentary replacement. They weren't in stock when I contacted them, but I was PROACTIVELY contacted when they were back in stock. I'm blown away by the product and service. Yes, they're 3D printed plastic, and more likely to break through mishandling or misadventure than something that costs 4x as much. But I think calling them fragile is an unfair exaggeration.

    VERY FRAGILE BROKE BEFORE I EVEN FIRED ONCE HAD TO ORDER DONNYFL METAL IS BETTER THAN PLASTIC
    Reply from Terry:
    I agree. Metal is more durable than plastic. DonnyFL products are great. I try to make this clear up front with folks. You've been refunded.

    I love my little Beeman, but the shooter at home it was a little too loud, so I try filling up the factory shroud with foam that help a little then I tried venting it that help a little more then I use Buck rail stripper that help a little more and for some reason I think the accuracy of my rifle more reputable then I try the suppressor and that made it really quiet. Now all I can hear is the hammer striking the valve. I’m pretty happy with my purchase. It took a little more than a week to get here. It was pretty expensive and it seems well done for the price now if they have an adapter so I can use it with my other rifles that would be the ultimate.

    While it worked m, it worked great. But less than 100 pellets through it, experienced barrel strike and and blew the front right out of it. The suppressor was on the beeman .25 underlever from the first shot fired through the rifle. Very disappointed. This was purchased to make have a back yard friendly plinker for the kids and without the suppressor, is not achievable. Will be going to Donny I guess.

    The first uni-adapter broke when I took it off to show a buddy the difference in sound. They replaced it right away. Good customer service but a little more engineering is needed I think on the adapter part.

    You need to let folks know that the adapter is very fragile, to be careful when screwing it in, I wasn't being forceful and the thing broke right near the top, so I think people should know to be very careful with it. Cause it ain't cheap. Sorry no photos, I was so pissed I threw the damn thing in the lake, I never got to even try it once.

    Similarly, I went to tighten into adaptor and it cracked. Unsure if it was me or shipping that did the damage. They immediately had one in mail day of me contacting. Awesome work!

    Worked well, BUT the threads were too tight. The suppressor would only screw on 1/2 way.
    I had to lightly file the threads with a 60 degree file to get the suppressor to screw on without using too much force.
