Even that is a little strange, I've never run a chamber reamer but my understanding is that there are no adjustments, you buy a reamer for the chamber you are going to make and run it into the bore till it bottoms out. If this is the cause of the problem as in he stops a couple hundred thou short of bottoming out to create a "tight" chamber I think that is stupid, these are semi auto rifles and need a little wiggle room to run reliably and run different ammo without headaches and frustration for the owner. The gain in accuracy would be so small it would be almost impossible to measure and since in this case it won't work with the factory ammo he's using it's impossible to measure.
Griffin,
Did Ian tell you what ammo he tested it with? Have you switched to something else? He didn't ask and I didn't tell him what ammo. I'm using Hornady 250 FTX, I haven't tried anything else.
I would call Ian and arrange to send your barrel and bolt to him so he can inspect the chamber and fix it if necessary. Sending the barrel alone should save you a bunch of money on shipping. I might ship him the rifle after I eliminate all the variables on my end
As for the safety, google how to take it apart, you only need to remove the safety as if you were going to remove the trigger pack from the rifle then pit it back in, I'm pretty sure it's just installed incorrectly or has popped apart. It should be an easy fix.
If I had it here I could fix it for you (if it's what I think it is). It's very simple to do once you've seen it done. I've had everything apart before to change the trigger, I switched from Stock>Super ACR>Super 3 gun and it hasn't given me any problems.
