What caliber do you want?
Have to start there to narrow down the choices.
Arsenal no longer deals with the Russian SGL line, FIME Group took that over. They are still the same, just a different name on the side of the receiver.
Arsenal only does the Bulgarian SLR line.
I own an SGL21 and a SLR106. I personally prefer the SLR106, but that is because of caliber, both are excellent rifles.
