Well, we've all been waiting for this one in eager anticipation, and it's finally here! The Western Arms M4 CQB-R is every bit as good as we thought it will be, with surprisingly hard blowback along with good performance figures (300fps with HFC134a, 380fps with Top Gas). It is a truly exciting gun. Even though it is not the first blowback automatic rifle or even gas blowback one, it is the quite possibly the best one we have seen so far and we are sure that we will see an array of modification parts for this gun to follow - metal body anyone?
