I'll consider any caliber larger than the .223/5.56x45mm and any make/model. I'll know what I want when I see it. I prefer to stay away from the very big bore calibers due to limited range capabilities but still may consider one if it will interchange with other uppers of calibers that better meet my needs (i.e. .308, 300, etc).
I'd prefer a complete tactical style A3/A4 setup with scope, adustable stock, etc but will consider any rifle that is capable of being rigged with such.
If you live close to Washington, D.C., I can travel to inspect and purchase. If not, I have a FFL that is awaiting my order instructions.
You can email me pics/info at firstname.lastname@example.org if you don't want to post them here.
