AK bolt carrier has cracks - replacement suggestions

[Mike K]

When I took my AK apart to clean it I noticed that the bolt carrier has two small cracks where the piston threads into it. My AK only has about 300 rounds through it, so it is a little disappointing. However, it is a Lancaster Arms AK, so I guess I should have expected it.

I did a quick Google search and it looks like it is fairly common, so where can I get an inexpensive bolt carrier?

Drill a small hole at the bottom of the crack and then de-burr the hole.

Cracks in an AK? You mean ventilation ducts?
