The ZR9 Billet Lower is machined from aluminum in-house. Along with its over-sized mag release, the lower features massive magwell ramps to aid in reload; a feature not found on any other PCC lower. ZRTS has tested with Glock, Pmag, and ETS magazines for complete reliability. All of our 9mm lowers ship complete with mag release and ejector.
These lowers are in 80% configuration and are not considered firearms. They can ship directly to customer.
They DO NOT have LRBHO as all AR9-Glock platforms have proven unreliable and inconsistent due to the heavy mass and spring rate. The Glock follower and spring was not designed to hold back such a large reciprocating mass. For competition and tactical use, it is better to be consistent so we have chosen to have a lower that never locks back on empty (similar to an MP5).
Our lower also works with +10 and +20 extensions. As with all ZRTS lowers, the design is completely roll pin free for ease of assembly.
Lowers are available in mil-spec black anodize or tumbled, raw finish.
