NVTS (Nautilus Variable Timing System) is a muzzle device timing system developed by Swiss CNC, with design input from Forward Controls Design. We don’t usually use abstract names for our product names, in this case, the shape of the timing mechanism bears an uncanny resemblance to the marine cephalopod, we think it’s an apt name and description of this marvelous invention.
NVTS consists of 2 interworking components: a base and a disc. The base has 12 tick marks, each tick mark corresponds to an hour on the clock, or 30 degrees. NVTS is shipped set to 0 degree, with the arrows on the disc and base aligned.
* With the muzzle pointed forward, place NTS on the barrel with the tapered end facing the muzzle’s shoulder. Hand tighten the muzzle device on the barrel to determine the number of degrees required to time it.
* Dial in the amount of timing required. For example: if the muzzle device’s center slot/port points to 10 o’clock after it’s been hand tightened with NTS installed, back out the muzzle device and NVTS, remove the disc from the base, rotate the disc to the right by 2 tick marks to add 2 hours to bring the center port from 10 to 12 o’clock, then add one more tick mark to account for torquing the muzzle device 20 to 30 ft lb.
* Do not exceed 45 ft lb torque value. Excessive amounts of torque will cause damage to the barrel extension.
NVTS (patent pending) was developed and manufactured by Swiss CNC in Montgomery, TX, with input from Forward Controls Design on ergonomics and user friendliness.
Precision machined in 4140, with Swiss CNC developed, patent pending QPQ process which provides superior protection against salt spray corrosion, makes the material malleable, durable but not brittle. Tensile strength:150,000 PSI, hardness of 48-52HRC.
Length: 0.178 (as shipped, set to 12 o’clock or 0 degree) to 0.217 (set to 11 o’clock, or 330 degrees).
Solid design and great execution, but I still had to use a thin shim to get one muzzle device to time correctly. I would still use it on future projects, though.

The NVTS is a solid, quality time saving product. Whether you’re looking to time a MD for left or RH shooter (or 12 Oclock) you will love it. Fast, Simple, Easy ; )
