The only thing that pisses me off about the Caiman guns...they don't come with a filler port plug, at least mine didn't. And they cost $10 to buy, for a damn piece pf plastic.
Other than that I really like mine. Zero complaints. And yeah, I've owned, and still own, true bullpup powder burners, so I'm plenty used to shooting them To me, there is LITTLE difference in shooting a bullpup and a standard rifle. Except, that I like shooting the little guns better ! Easy transition from one to the other.
On my Caiman, I removed all of the factory baffles and installed the short, small diameter 0dB suppressor on it. It's MUCH quieter, and just a little longer than having all of the original baffles in place. I put two of the Caiman baffles onto my Caiman X. That helped quiet it a "little" more, without adding too much length. The 0dB "fits" the Caiman, size wise.

Note - I now own both the Caiman and the Caiman X. Wasn't supposed to happen, but it did ! I haven't noticed a regulator problem. No noticeable creap, and pretty similar shot to shot speeds. At least the ones that I tested shortly after buying the "X" version.
