To start with there is almost no such thing as an original Browning. the BLRs were made for a short time by FN then have been made ever since by Miroku. All Browning Firearms are made under contract.
I have a 308 stainless pistol grip non-takedown, and before that a 308 Lighting. It shoots accurate enough for me and has never given any problems. I would buy another one which should say something.
Triggers by reputation can be average but can be improved.
I think what gets forgotten with these is they by design are not a long range platform. If 300+m is your regular thing then buy a bolt action (I know you asked about 223 but this is in general). Inside this range if you want an easy carry compact carbine with the fastest follow-up up shot we are now allowed then go for it.
