Gary56, honestly speaking, I think if you get the Gen 2 Templar, you'll probably get a rifle that will do fine. Just be aware they are not X95s, Bren 2s or B&T APC 556s, and don't expect them to be. With buffer tube models now at $1600 they're not breaking the bank.
I have had a single issue with the operation of the 5.56 "Sentinel" (a Templar Gen 1 upper) half of the Dual Caliber Combo with the e-clip that holds the bolt hold open on the lower. Once I knew to monitor that e-clip for walk-out, it hasn't given me an issue since. That specific part, the lever-actuated bolt release/hold open, was replaced in the Gen 2 with a more conventional AR15 bolt hold-open paddle, so that's not likely a point of failure any more for Gen 2s.
Now, I'm not saying you should buy an Crusader Arms Templar Gen 2 as the best possible 5.56x45mm rifle - for best value for money I would buy an NR X95 or a restricted barrel length Bren 2 - both can be had for under $2500 - another option which is less reliable than a Bren 2 or a X95 but probably slightly more reliable than a Crusader is a Lockhart Tactical Raven 556. If you like the look of the Crusader and don't mind the possibility of a few small maintenance/reliability issues, go ahead. It's a risk, but then you've got something which you prefer. Everyone should weigh the risks, rewards and value for money when buying a firearm.
I do not recommend the Crusader Arms Templar 2 as a SHTF rifle; as much as I'd like it to be capable of that level of utility, it doesn't get over the bar of reliability and portability. As an accurate, easy to disassemble, easy to clean firearm that shoots comfortably, it seems to work fine for most users. There are, of course, exceptions like Nicodeco - who is experiencing a legit and challenging issue with the weird piston problem they're seeing right now.
I do not recommend the Crux or the Crucible at the moment. It's clear there are design/QA/QC issues with both of those products.
It also appears clear that pre-ordering from CA or expecting good comms with sales or if you have a shipment or payment issue with them, that you are not likely to get satisfactory responses.
