Even among 700 Clone Customs, you’ll find a variety of action footprints which will require changes to the stock inlet. “Fitting in the stock,” in that case, is different than “dropping in without inletting or other modification.” But MOST stock designs on the market will accommodate a 700-ish footprint with only mild modifications.
A guy has to consider the fact there really are no other action designs being “cloned” in the market. The 700, tube style design isn’t the best design for every application, but it certainly seems to meet a particular price point balanced against an overwhelming majority of applications. For hunting, the lightweight, tube design is a distinct advantage.
For the money, there’s nothing about the Nesika action which would convince me it is worth owning over a Defiance, Impact, or Surgeon. An action with a pinned lug, bolt-on rail, and Savage-style extractor for the same as or higher MSRP than an integral rail and lug model doesn’t make sense to me.
Personally, for lower cost and upgraded features, I’d not even blink to look over a Nesika for a Defiance. Glen got a lot right in the redo. For $200 more than the Nesika Hunter, a guy can get a Ruckus with drop in barrels (headspace controlled actions), integral lug, integral rail, and M-16 type extractor, or for about $150 LESS than the Hunter, the Defiance Tenacity has an integral lug, drop in barrels, and the M16 extractor...
