I'll take a chrome-lined 1:7 GM barrel over the 1:12 Israeli barrels, thanks.The Caspian receivers are apparently way better than the ORF made ones but of course that did not guarantee a good build since Century was still behind them. Plus adding a Green Mountain barrel no thank you I'd rather have the IMI original barrel.
The Caspian receivers are better (SN begins with "GLN", IIRC), but they are by no means perfect, and do have some problems.
