Where are the KWA LM4 GBBRs (and TT-33)?
From KWA Central Article.
According to KWA in the KWA Technical Forums, “the new upgrade parts are being manufactured and should be shipped to [KWA] sometime this week. [KWA] anticipates [the] release of products in the 3rd to 4th week of May.” In addition to their response “[KWA] sincerely apologizes for the long delay but [they] are certain the LM4 will be worth the wait.”
From KWA's response in the KWA Technical Forums, it's probably safe to assume KWA LM4 and TT-33 will be out by mid May.
