It looks cool, but on the gun; it's fat. Thick. Tall. May partially obstruct the view of some very low mounted scopes.
It's pretty heavy at approx 7 ounces(with caliber specific air stripper installed) which is comparable to a Shogun(approx 6.8 ounces).
I have only started testing it by using .22 caliber ammo at different speeds out of FX Crown barrels(380mm, 600mm, and 700mm).
The sound reduction is comparable to a Shogun, but sounds slightly different(more muted tone or shorter duration maybe?).
The way it affects barrel harmonics is very similar to the Shogun. Ammo at whatever speeds work well with the Shogun, work well with the Fat Boy 2.0. When replacing a Tanto, Tatsu, DonnyFX, or Sumo with the Fat Boy 2.0, I experience wider group sizes(which were tightened back up with a change in speed) AND POI shift(mostly lower), which had to be adjusted on the scope in order to correct.
It does offer a lot of flexibility with the ability to shoot multiple calibers out of 1 moderator, but I don't think it would be very useful for someone who is already getting good performance out of a smaller moderator like a Tanto, Tatsu, or DonnyFX OR has a smaller caliber and/or compact gun.
*Update*- 100 yard comparisions between the different sizes of air strippers. I used this short barrel, fairly high power rig to test because it really produces a big "cough" of air out of the end of an un-moderated barrel:
I used the same POA for all air stripper sizes. Top row on the 1st target was shot this morning in near calm conditions. The bottom row was shot 30 or 40 mintutes later when the sun came up and a light breeze started. 5 shots per bull on this target:
I decided to shoot 10 shot groups at each bull on this target in slightly stronger light and variable breeze to maybe provide a better idea of what is going on:
Each size air stripper produced a distinctive different sound/tone. Granted, I was using a .22 cal to test all sizes. They all moderated the report of the gun nicely, but was hard to tell which one was "quietest" because they each had a different pitch or duration or something. I could definitely notice a difference though. The .177/.22 sounded maybe a bit "deader" than the other two. I expected the .25/.30 to be loudest, but the .25/.30 just sounded like more air was coming out(maybe "breathed" a little more?), but it had a much shorter duration, so I can't say that it sounded "louder".
