The M14E2, later redesignated the M14A1, was the replacement for the ill-fated heavy barrel M15 rifle. Both were intended to fill the role of the BAR in providing automatic fire in support of M14 rifles. The M15 program was cancelled before any rifles were built, and the M14E2 that replaced it was simply an M14 with a pistol grip stock, bipod, forward grip, and bipod. While it was more effective in automatic fire than the standard M14, it was significantly inferior to the M60 (no surprise there). A total of just 8350 were made. This particular one is a well-done semiauto copy made on a Springfield M1A receiver, so it can be owned without NFA paperwork.
