I have one inbound for my own detailed analysis. If you would consider buying the WS-MCR, then consider this a greatly-refined and evolved WS-MCR with an AR15-style Lower Receiver, a Monolithic Upper Receiver (solid aluminum top Picatinny Rail), a thicker one-piece Piston, and a "Magpul ACR style" Buttstock. All wrapped up in a package with quality of machining and finishing that is on-par with the WS-MCR. A few external machining marks here and there, but nothing that will compromise function or performance. I expect the Medium-contour Barrel to produce 1.5 MOA with 69 gr Federal Gold Medal Match and 2 MOA with bulk 55 gr Aguilla M193 Ball ammo. Hits on target will tell the tale once I receive the rifle this coming week.
You are right to be hestitant with true, untested, first-generation rifles such as the BCL "Siberian" which is a new design rushed to market with the preorder funded by Beta Testers. Don't be that guy! In the case of the Templar however, it is really the WS-MCR "Gen 2", and in that sense it is a tried and tested system that has been further enhanced with vastly improved Ergonomics, Trigger (Trigger Tech Adjustable), Piston, and so forth. The AR-180B operating system is a well-known "done deal" at this point, and all that remains is to further refine it by beefing up the Piston (done), and similiar small upgrades. What I'm saying is that the Templar is a pretty safe bet as the "WS-MCR Gen 2"....
At its proffered MSRP of $2250 with the (might as well be mandatory) Trigger Tech upgrade, the Templar offers a solid build and performance that is presumably even better than that of the WS-MCR that preceded it. There's not much else at the $2K price-point these days to compete with the new Templar, and certainly nothing in terms of an established commercial product such as the Tavor X95 ($2750) or CZ Bren 2 ($3200). So the Templar finds itself in an advantagious position price and performance-wise. maing it a new platform certainly worth considering. Closer competition would be the Keltec RDB Bullpup equipped with an Aluminum Handguard ($1800), or the Sterling Arms International R18 Mk2 ($2700), although the latter is considerably nicer in terms of parts fit and surface finishing as the higher price would suggest. I predict that the Crustader/Spectre Templar will prove to be a solid, if uninspired AR180B derivative design, providing reasonable accuracy and reliable, rugged performance. Assuming there are no unanticipated parts fairlures in the "new" Charging Handle System employed on the Templar, it should be good to go as most of the rest of the operating system has been in successful production for several years now as the WS-MCR.
