I had issues with my 7.62x39mm CZ BREN 2, nothing since then. The Carbine works quite well, but it has only had about a hundred rounds through it - it's too HOT. Parts are a REAL problem, and Colt is running the show now, we can only wait and see. Maybe the Ukraine facility will move from assemblage to production, which will ease the parts shortage as they go into Ukraine, Hungary and the Czech military. Perhaps someone at Colt will realize they should import some tooling and dies to make spare parts here in the US, I don't know, BUT they should be happy to be part of a company that actually HAS military arms contracts.
