R&B Arms AR15 upper build – OV-series

Here at R&B we are sick of buying a complete AR15 Upper that has a lame a2 bird cage and a standard milspec charging handle. With the OV1 Build option you can add the finishing touches to your complete upper. And best part is your going to save a little bit of cash while you do it. That’s right, finish it you way and save!

Our OV1 upper is out first upper in our operator line of uppers. These uppers offer a precision barrel, free floating handguard, and ambi charging handles to start. Now its your turn to add the finishing touches on you OV series upper. Select from a base (upper barrel and handguard) and add the finishing touches. select you BCG, your charging handle, muzzle device and any other extras you may want to add. Build you upper the way you want it. No lame A2 bird cage, or milspec charging handle that your going to change later.
