Thanks for the input guys - and it sounds like I'm going to have no problems - at least equipment-wise with this.
Just to give a little more fidelity on the situation - I was asked by a co-worker if I could help with a hog eradication problem on his property at relatively short notice, turns out, I have all the
toys, erhm,
tools for hog eradication that he doesn't have (ARs, IR lasers, NODs) - and of the two rifles that I have with zeroed IR lasers, one of them is a 10.3" M4A1 CQBR clone - and the ammunition is what I had on hand already (will be reimbursed
) that wasn't just FMJ plinking ammunition.
Given the fact that I don't really have the time to re-zero another rifle with an IR laser before the scheduled date, I was just wanting to make sure I'd be good taking the CQBR "as is," or if I needed to make time to zero something else.
Meanwhile, I'd been considering the possibility of converting one of my CQBR uppers to a .300 BLK, and depending on how this goes, I might just end up doing so - I also wish I'd had a chance to order some Barnes TSX, but was unable to, so, as I said, I'm going with the SD/duty ammunition that I have on hand for the task.
Will try to update with how it goes - hopefully I'll have more than stupid questions to share next time!
