A look at the heavy AEGs from E&C which are based on Heckler & Koch designs with Begadi upgrades, SMR17 and SMR28, in this review by REAPERs Airsoft. These AEGs are entirely metal-constructed, with the exception of the handle and stock. They feature a CNC-manufactured aluminum handguard, a 21mm rail for optics mounting, and a CNC-machined flash hider.
