Quoted: Hello All,
I would like to build a 16" Krink now, then convert it to a SBR when I move to Arizona next fall (currently in MI, a non-nfa friendly state).
kit: http://www.k-var.com/product.asp?0=211&1=214&3=508
Question 1: When I cut the barrel down from 16" to 8", what will I need to do? I assume I will need to open up the gas hole from the barrel ala AR15 SBR's. Will I need to change the gas tube or piston or any other hard parts?

Don't think you'd need to open the gas hole. You *SHOULD* need only to cut & crown the barrel. Use the existing crown as a guide. A basic 90-degree crown would be OK.
Keep in mind the Krink is/was underpowered and that's why it has been replaced w/the AK-105. The muzzle booster (what everyone normally calls the "Krink cone flash hider") was designed to help with the low impulse. I'd recommend you use one when it is SBR.
Question 2: What do I need to buy for this K-Var Krink Kit besides a trigger guard? I've got a OOW reciever and a RSA trigger and FAL style US pistol grip already. Anything funky with the krink kit?
Thx!!!

The Krink uses all the normal internals - it is a normal AK from the trunion-back. So you should be OK.
Mitch is correct while it is a semi-auto sporter rifle. Once you SBR the parts count no longer applies. Logic is that the rifle is no longer a semi-auto sporter and therefore the crime bill doesn't apply.
Keep in mind that, due to the serial number registration that is required for SBR paperwork, you will have to use a store-bought (aka commercially produced) receiver. Since a BIY from an 80% flat has no serial number, you can't register it. You COULD register the rifle but you'd have a ton of red tape - using a $60-$75 commercial receiver would be infinitely easier for the money.
