I just purchased a Kriss, brand new. Any advice?

Hi there, just purchased my Kriss and I'm looking for any Do's or Don'ts with them and buying gear for them, I did already buy 4 of the extended mags and a speed loader, but other than that I've got nothing. Any advice on sights, ammo, slings, anything, more than welcome to post with pictures/links to sites/ect. Thanks!
My main question is whats your choice of sight for your kriss? I'm looking to put a sight on it. I noticed the tac-pac came with an EOTECH Sight model 512.A65. Any advice is welcome

Check the boards. Lots of opinions. Aimpoint or Eotech. Can't go wrong with either one.

Just start reading the threads here. I don't even have one yet, but I've been reading/researching for a couple weeks!

Anything you can think of has probably been covered to some degree on here, you can do a Search for specific terms, such as "optics", "charging handle", "magazine", etc.

No such thing as best sight -- its all personal preference. Kriss sells EOTech and has wallpapers with Aimpoint.

congrats on your gun. if you have function problems, i have noticed the extended mags have weak springs that cause malfunctions. have a non extended glock mag around to test the gun.

these guns are finicky.

have different types of ammo on hand.

mine is now sbr'd so i can't compare the function with a
carbine but those two items i mentioned above have been
issues with my rifle.

cheers,
