The gun was and is a great value. Is it up to custom gun standards? I doubt that anyone make such a claim. It is, IMHO, the best gun buy in this price range and a helluva shooter.
If I were to pick the best of the RBL's, there is no question that it would be the RBL-28. It's lightweight with the feel of a custom gun costing much more.
The worst is the RBL-16 which is overweight and handles like a bottle bat....OK, (I'll be nice) maybe a Model 21.
The RBL-20 falls somewhere in between.
Most owners are very pleased with there guns can live the much publicized imperfections, real and perceived.
I think CSMC has done much better than they ever imagined. It's my understanding they spent a great deal of time increasing production capacity to fill the unexpected demand.
You can no longer order an RBL. I assume that means they've ceased production.
