I have a virgin Bulgarian kit. I fell in love with an AK 105. I Know the gas blocks cannot be found.
My question is it possible to cut a us chrome lined barrel to 14" and weld the Bulgarian break to make it a legal/non class III 16" barrel? Or will there be gas problems etc? Thanks in advance.

Yes you can do that, move the FSB back to directly in front of the Gas Block and permanently attach the 74 break. this will put you at a little over 16". Should'nt have to mess with gas port size although My post sample 105 has the gas port size for the 16" barrel which makes it run at a slower RPM than others but I have never had a failure of any kind... AK Gas systems on the 7.62 and 5.45 are pretty forgiving, modifying .223/.556 is when they get finicky

Here are some similar threads;

I believe the OP as mentioned above is trying to achieve a barrel length similar to an AK-105, instead of trying to source a 105 FSB/GB he wishes to simply use the parts he already has to achieve a similar result.

I will probably build one like this myself because I think it would be pretty handy and the MB would help a lot with follow up shots without adding overall length to the gun. Would be the perfect truck gun.

Another option is put a Romanian, Polish or East German wire side folder on the rear and it shortens it a lot more.
