Hello, Son of the owner here to clear up any misconceptions. To start we were founded ten years ago when the owner of Ohio Rapid Fire (Todd Groves) sadly passed away and we bought out their inventory. We continued to sell their previously manufactured receivers (m70, Vz58, FALs, gallils, etc. ) up until about 2017 when we ran out. we've also started manufacturing M76 receivers since 2015 do to the high demand of M76 builds that we have been producing since 2010. The new Vz58 receiver s are now manufactured by us. We've hired CNC programmers to remove the old tweaks that people had to make on the previous Vz58 receiver so its easy as possible for someone to build on. That being said if you purchase one from us and you manage to find a manufacturing flaw, we replace it free of charge and make adjustments here accordingly.
