PLEASE NOTE: Beeman offers these airguns in two barrel sizes. The only way to know what barrel size you have is to measure it, as far as I know. Please measure your barrel and select the size that will best fit your airgun. I don’t know how tight or loose Beeman’s tolerances are. If it is too tight you may need to sand or drill out the ID to get the fit you need. If you’re not comfortable with this please do not purchase. I’m just trying to provide a niche service at a great price.
This kit includes a threaded clamping adapter, suppressor, and thread protector. The suppressor adapter was designed for and tested on the Beeman QB78 Deluxe, but it should be compatible with other airguns in the Beeman Power Series. The adapter doesn’t require any modifications to the airgun. It just slides onto the barrel and clamps on with two stainless steel socket cap screws and nuts. It uses the same threaded suppressor and air stripper as our Crosman 1077, M4-177, 880 and 13XX kits. The suppressor includes 7 cone-shaped internal baffles. If you’d like to shoot without the suppressor you can install the faux stripper as a thread protector.
You have the option to select the adapter only. The adapter will come with the thread protector, but no suppressor. You might select this option if you already have one of our UNI Suppressors and don’t mind using the same one on multiple airguns and want to save yourself some moneys!
- Ensure adapter socket cap screws are loosened
- Slide adapter onto barrel shroud while aligning slot with front sight post until bottomed out
- Use an allen wrench to tighten the cap screws on the adapter
- Thread on the suppressor or thread protector as desired
PLEASE NOTE: I used to make the suppressor with a larger opening than necessary to avoid any clipping issues, but have decided to tighten it up for maximum report suppression. This will increase the likelihood of pellet clipping. If the accuracy of your airgun is affected you may need to drill out your suppressor little by little until the accuracy is no longer affected. If you are not comfortable with this please do not purchase. But it’s not bad. The drill bit will self-align using the baffles like a pilot hole. Make sure you remove the suppressor from the airgun before you drill it out.
