New... November 2025!

The Beeman Underlever PCP Bullpup (Model 1357, 1358 and 1359) have turned out to be a really great shooting air rifle. Smooth cocking action, decent trigger, and good fit and finish. Available at most larger airgun distributors at an affordable price point.

The factory rifle shroud design lends itself for improvement, and the AGM-B13xx shroud extension is a quick, easy way to hush it up! No adapter is needed with the AGM models for the Beeman.

Take a look at the installation video, then let us know if you have any questions.

The AGM-B13XX model fits the Beeman Underlever PCP Rifles (.177 B1357, .22 B1358, .25 B1359) Curently only available in black.

Easy, quick installation

Adapter is NOT required
