Like for like: these are not the same use. The Sierra 5 is rated for 5.56 NATO and 224 Valkyrie and the Nomad 30 for up to .300 Norma Mag, so size and weight reflect different caliber classes. The Sierra 5 page lists length and weight with no adapter and with Xeno; the KeyMo configuration is not yet verified, and we do not subtract across undefined mount bases. The Sierra 5 prints $859 in its Specifications block while its store listing shows $899.00 – $979.00; we show both and no single street price. The Nomad 30 body copy says “just 14 ounces”; we use the 14.5 ounces from its Specifications block. A blank is not a “no”: the Nomad 30 block we read has no Finish or Full Auto Rated row. Dead Air prints no decibel figures that we read on these pages, and we show none. Suppressors are NFA items; see how to buy a suppressor.

Which to pick (on paper)

If the shortest, lightest can matters: the Sierra 5 at 4.87 inches and 10.8 ounces with no adapter (5.72 inches and 13.3 ounces with Xeno), against the Nomad 30’s 6.5 inches and 14.5 ounces.
If the higher energy rating or larger caliber range matters: the Nomad 30, at 4400 ft lbs and up to .300 Norma Mag, against 2200 ft. lbs for the Sierra 5.
If a printed full-auto rating matters: only the Sierra 5 page lists it (Yes, with no barrel restrictions). We have not verified either for the Nomad 30.
If the printed MSRP matters: $949.00 for the Nomad 30 and $859 for the Sierra 5 in its Specifications block, with a store range of $899.00 – $979.00 shown on the Sierra 5 page.

We have not range-tested these; facts above are from the makers.
