Yea I was reading about ADCO pricing but the biggest problem is 2 way shipping. I have used them before and they are good, no doubt. Their listing says they'd only charge $30 for an A2X. Not sure why it is so cheap and then for like a Surefire they charge $85. I guess I can send the barrel to them off the upper to minimize the shipping costs. The other thing is that on their website in the pics it shows their work, and they def don't alum black over it. I know some people say not to so you can see the pinning to prove it was done. To me that's bullshit if you have the receipt and if the inspector or LEO tried to twist it off and it didn't move.
