The CMMG Echo is a .22 LR AR conversion kit that turns a standard AR-15 into a low-cost training and plinking rifle (brand part no. 22BA64E). CMMG builds the kit around steel construction in a black finish and includes an anti-jam charging handle, a cleaning jag guide rod, and a forward assist adapter for compatibility with forward-assist-equipped uppers. A 25-round magazine keeps range sessions going longer between reloads, and the kit’s 10.3-inch length matches a standard AR-15 bolt carrier group footprint for a straightforward swap. It’s an economical way to put more trigger time on your AR-15 platform without burning through centerfire ammunition.
