Hillbill;
" ...im thinkin of customizeing my ak."
I would suggest that you be very careful. First of all there are few "AK's" in the U.S. Most of what folks own are MAK's and other semi-auto's. In modifying one of these firearms, one needs to be very very careful that one doesn't run afoul of BAFT regulations.
If I were the ownder of a modified AK or MAK, I certainly would not recommend showing a picture of one, for fear that some BAFT agent would spot something he determined was an illegal modification.
Until such a time as the Assualt Weapon Ban sunsets, one can get oneself in all kinds of trouble for modifying an MAK or even purchasing the wrong parts.
I may be getting a little paranoid, but this is the second post in a row that I have looked at where someone is asking for help along a grey area of the law.
Assuming you are just a plane sportsman, then I really recommend you check with BAFT or a good gunsmith as to what modifications might be legal for you MAK or AK-semi-auto-clone. Be very careful in your modifications so you don't run afoul of the laws.
