I have one in 308 that is the Belgium mfg (pre 81).
I also have a BLR 81 with a steel receiver in 223. Both are smooth and reliable. The 308 will shoot 1 1/4" groups with factory ammo, the 223 is sub moa (I now do not shoot factory ammo).
I have heard of problems with the gear that the lever operates but never hear these stories first hand.
On 24hourcampfire there is a thread you may find interesting on the BLR
