Black Rain Ordnance charging handles are 100% cnc machined from a solid block of 7075 T-6 Billet.  Each charging handle is engraved with the words BLACK RAIN.  When coupled with a Black Rain upper receiver, the two come together to complete the biohazard logo that is engraved on the upper receiver.  A truly unique feature in the AR-15 industry.  Add to that the fact that all Black Rain charging handles are made in the USA and the engraving down the spine of the handle boasts that fact.  This charging handle has great features and will compliment any AR-15!  We clearly mark every piece that we make for a reason.  We believe in our products and want the consumer to know that if they purchase a Black Rain Ordnance part, they are getting the best quality available.
