For what it's worth, the Sentinel(which is functionally the same as the Templar) went for around $1600 or so with a buffer tube and stock. That F5 "ACR" stock sells for $300usd and bumps the price up to what it currently sits at ($2000 with a milspec trigger). I'd imagine that if there was a demand, Crusader could offer the Templar with a buffer tube and stock at a lower price point since it would require no modification whatsoever.
This is a great point.
Crusader can change the look/appeal by having some of the Magpul (or other) fixed/telescoping stock options.
Besides the buffer tube and stock, what other parts does one need to change out the F5?
