I took off enough material to make it shiny inside just by running the charging handle, nowhere like the gouge, just maybe a mm or half that.
I did this just by pulling a little away from the receiving while pulling the handle back.
So I'd imagine anyone under a little time sensitive match stress would cause the same wear.
I don't think this one of mine could actually jam the action to a stop - but a little more clearance for the handle to tilt(for whatever reasons, undersized part or something), I don't see why it couldn't happen.
If there wasn't a magnet there - so the hole was deeper, and the handle base was bigger - I would think it wouldn't be able to pull out enough to tilt.
Bevel the edge and it wouldn't gouge as it rubs the inside. Make the cheap to replace handle a softer material than the more expensive receiver.
So just having it float in the hole would be a lot more sense than the current set up.
So, someone over thinks to solve a problem that doesn't exist it seems, and turns it into an actual problem.
I'd love to hear what the actual designers thought of all this talk.
Ya, it sounds like they fixed a problem they created themselves with a band-aid.
As I've said, my 180B-s has nothing holding it in other than the receiver and I have zero wear inside my receiver from it after well over 1000 rounds.
If the carrier and CH were machined to tighter tolerances and bevel/radius the edge of the CH a little it should be a non-issue.
The stamped steel receiver of my 180B is going to be a better material for that type of thing but since the Aluminum is anodized it should be hard enough that the CH should just slide along it.
Almost need a sleeve for your CH, that's way too much slop.
I would think a spring clip/ snap ring (whatever you want to call it) on the CH that has a groove to snap into inside the carrier would be better than a magnet and or threaded bolt. Or as I suggested earlier something like a QD cup setup so it's retained. Threaded is not ideal on something like that where you'll be grabbing with gloved hands and yanking it during reloads, unless it's torqued in it's just going to come loose and if it's torqued in you no longer have the ability to field strip your rifle without tools.
They should have let me be a beta-tester. I don't pay for that though, I like to get paid to do stuff like that.
I was on the list to be a tester for Canada Ammo when they were working on a 180 upper, payment was going to be a completed upper at the end. Unfortunately they gave up when this rifle and the RWA upper started coming to market. Guess they didn't think there was enough market for another one at the time. I think it would have sold, especially if the price was right and barrel swaps were easy or if different calibers were offered.
In my opinion you should get a free replacement carrier and CH at minimum, if there is actual damage from it maybe a new receiver. That's not acceptable and I would guess that based on my communication with Kodiak so far they would take care of you if they knew how much slop there is in your system, that's not normal wear, that's wear from an out of spec part rubbing where it shouldn't be.
I'm kinda guessing that they don't realize how loose that CH is in the carrier, I doubt there are many others like that, seems like a machining oops.
