Bullpup, pocket sized
A pocket-scale tribute to the Belgian bullpup PDW silhouette of the late 1980s: stubby frame, wrap-around grip and that unmistakable magazine lying flat along the top rail.
Ours arrives as a kit rather than a single lump of metal. Pull the magazine, swap between three optics, thread on the suppressor, and reconfigure the whole profile with the included miniature screwdriver whenever the mood changes.
Machined edges, threaded steel hardware and no plastic anywhere — equally at home on a keyring, hanging off a pack strap, or parked on a desk.

“Came in a hard case with every part bagged separately. Took me ten minutes to build it and it hasn't left my keys since.”

“Second GRIMWERK piece on my desk now. The P90 is bigger than the pistol but somehow still pocketable.”

“Screws are real screws, the rail is a real rail. Swapped the optic twice already just because I can.”

“Hangs off my backpack and gets a comment basically every day. Heavier than expected, feels solid.”

“The bullpup shape is what sold me. Suppressor threads on smoothly, no wobble at all.”
