HM Defense Produces a Proprietary Patented Integral Gas Block for Incredible Performance

If you have ever just sat and pondered the problems which could plague the AR platform, the gas block could have crossed your mind. HM defense has developed a revolutionary patented design with a gas block that is integrally machined as part of the barrel. This eliminated gas block installation and alignment which is a common failure point for the home builder. This not only improves barrel harmonics for better accuracy but it provides you with dependable performance even in severe conditions. This upper receiver represents a high quality offer from HM defense that will allow you to connect to your Ar-15 lower to see the difference for yourself.
