    I had broke my original purchased suppressor while storing it away in closet. I emailed Buckrail explaining my damage along with photos to confirm the proper replacement. I was surprised when a new suppressor and mount arrived to my residence, No Charge even though my fault, an outstanding business model and will be patronizing and recommending to my friends who are into air rifling.

    I purchased this for the .22 version of the Underlever. In order for it to go all the way into the barrel and screw into it, I had to shave off quite a bit of the raised angled portions of the inner end (I know they have a name but I don’t know it!) with a small sharp knife. Before I did that I could see it bulging the shroud as I tried to insert it without forcing. I stopped and decided to make the ends smaller to better fit inside the shroud.

    I suggest re-evaluating the girth of the end tabs and making them lower by a very, very small amount. Unfortunately, I wasn’t happy with the Underlever as despite playing with the hammer spring adjustment I am still getting only two mags per fill and it is still loud despite using the suppressor. None of that is Buck Rail’s fault. I just thought I’d mention it in case others had the same experience. It will be going back to Pyramyd. I’ve asked Chris if I can send back the parts of the suppressor system I didn’t adapt . No response yet. Not a deal-breaker.

    At first I was not expecting much. I saw so many reviews on YouTube but editing is easy! But I "bit the bullet" so to speak and ordered the Beeman 1358 Suppressor kit and The Barrel band! They FAR EXCEEDED my expectations. I'm now ordering the FULL Umarex Notos tactical conversion kit for my Notos when it shows up. Absolutely love your products. Custom service is spot on and never have to wait for a reply.

    It's a great product and works like advertised. But mine broke apart after six shots of 25 cal. Was so relieved when buckrail replaced it with no charge. Delivery was fast and service excellent. I don't know if my first one came from a bad batch, second one is holding up.

    Love the UNI Adapter for the Beeman Underlever. Really like the ability and the look of the flash hider when not using the suppressor. On a side note, broke the UNI Adapter while installing on the rifle. Contacted Chris and he immediately sent me a replacement adapter. That to me is outstanding customer care...

    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.

    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.

    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.

    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.
