Range report with pictures of the aftermath. Need advice

Went out and put 350 rounds through the KRISS today and I am happy to report absolutely ZERO malfunctions. This makes almost 700 rounds with no issues. Looks like I got me a Wednesday gun haha.

My only concern is how dirty this thing gets, I am starting to think I may have over done the Hoppes no.9 when i last stripped it down. there was carbon and crap stuck everywhere. Need advice on what i can do to avoid it. Not a huge deal I suppose since the gun runs so well.
I was using PMC Bronze for 300 and Freedomunitions Reloads for the other 50





Might need to call KRISS about the stop?

And then after

Well... there are different brands of ammo that run cleaner than others (ex. PNW Arms KRISS specific ammo) which would help in that respect. KRISS USA maintains their approved ammo list for rounds that are known to function reliably... and part of that is running a bit cleaner. PMC Bronze is on the list... any reloads are NOT.

What you have in the pictures looks about "normal" to me for putting 350 rounds downrange with a wet/lubed setup. There are some folks here experimenting with "Frog Lube" which might help for a "less wet" (and easier cleaning) setup. KRISS USA also calls out for cleaning at the 400 round mark for these kinds of reasons. (See pg 14 below)

Agreed... that buffer needs to be replaced, and it's an older revision. If you have the time, it might be good to consider sending your Vector in for the once-over & update. (I can see from your other pictures your Vector is an earlier unit.)

Yeah no more reloads for me. Like I said I am not terribly concerned you want to see what everyone else was experiencing. I will be getting the revisions soon. I love this thing though haha
Now I need to go about shimming the xps2.

That looks so much cleaner than mine looked after about the same amount of rounds mixed with PMC Bronze, Golden Sabers, WWB, Speer Lawman & Remington UMC all in 230grn.

I don't see why you need to shim it. My friend's XPS2 cowitness but it is a lower 1/3 cowitness.

Yes Kriss will get dirty like that. And if you send it in. Make sure they send you back your original lower housing, if they replace it. I told them to do that and they tucked up and gave me a second updated lower housing. I will buy the early lower housing off you.

That looks normal to me. Vector is a blowback gun. It's part of the deal. At least it's easy to take apart and get some patches into. ;-)

Ok well I am not going to be too worried about it. Just though I was over oiling it lol.

On another note, I am heading to a range today to rent their SMG KRISS today as part of a birthday present. Woohoo!!!!

*UPDATE* got the eotech zeroed in at 25 yards. Added a magnifier just because haha. Another 150 trouble free rounds except for 2 instances when I would load a mag and when I released the bolt it wouldn't seat all the way. Not a huge deal I suppose.
