Problem is recoil

in a single shot rifle the shooter has time to get the rifle back in position before shooting it again. In a full-auto running 450 rounds per minute a 25 lb rifle is totally uncontrollable unless solidly mounted to a vehicle or fixed mount of some kind. A bipod or tripod just isn't enough. They have tried several times since the Vietnam war, hydraulic recoil cylinders, pneumatic systems, mechanical springs, none have ever proved to be able to tame the recoil and let the gunner keep on target.
