This suppressor was designed exclusively for the Beeman Underlever 1357 and 1358 PCP Airgun. It does not require an adapter to install and threads directly unto the 1/2-20 threaded muzzle. Just remove the stock baffle/shroud cap, press this suppressor into the shroud, thread it on, and shoot quieter! It is compatible with both .177 and .22 caliber.
It is 3d printed in Polycarbonate plastic in the great state of Texas, USA by a veteran-owned business. It keeps the original intent of the underlever designer (I spoke with him), but improves on the suppression by making use of 3d printing to make features that would be impractical to injection mold. It strips off some of the initial blast of air and directs it out of the suppressor and into the shroud. It also utilizes 12 cone-shaped baffles to slow the air as it escapes the exit, effectively reducing the report and making this fun PCP bullpup backyard-friendly. Take a look inside:
The total length of the suppressor is 7.8 inches but only 4.7 inches extends beyond the shroud. The larger outside diameter is 1.1 inches. The exposed exterior is textured with a honeycomb pattern. Have a look at the exterior of the model for more detail:
