Architect, Any experience with Spikes Tactical? Mil spec and great prices from what I can see. I like the looks of their ST-16 Mid-Length LE Carbine. Opinion?
I'm not Arch...but I've had Spike's gear in the past. They make good gear that would probably suit all of your needs, but if you have the cash...just pull the trigger on the BCM.
BCM will retain more value.
What most people don't realize is that if you actually plan to use the rifle...the cost of upgrading to a tier 1 quality rifle is moot in comparison to the expense of ammo, training, etc over the life of the rifle. Get the best!
