For a PCP, I'm a huge fan of the HW44. If you order from a vendor in the U.S. you can run into some issues with the set screws on the suppressor being frozen with some Loctite. If you order from Krale, the suppressor will be in the box separately. You can put it on and take it off with ease. Even with shipping, duty & taxes it was a little cheaper than ordering from AoA. Mine is .22 and I love it. I even put a green laser on it.
