FX M4 - Testing Moderators

Now that I have the M4 adjusted for velocity I started testing various moderators.
FX that came with rifle, very basic
Impulse Air 1350
Donny FL RYU - screw on version
Donny FL Yokozuna - screw on version
Donny FL Tatsu

so I tested all of them, the ones with sections removing a section one at a time. Most provided good results. The very best, most accurate and consistent is the one that came with the rifle. Plenty quiet and the slugs just land on top of each other. Obviously this is my gun only. Shooting NSA 31.2 .218 slugs at 1010fps.

I was just surprised how well the factory one performed. Basically a hollow tube and lightest of the bunch.

Do you have the 700 or 800 verison? Just curious.
