Agree 100% with above statements.....very little oil needed....and I clean mine with CLP also. That's great stuff. I just bought a new Blackhawk quad-rail fore grip for mine.....and I mounted a verticle grip on the handle that has an integral bi-pod in it. Push a button and out pops a spring loaded bi-pod,....That's the shiznit!!! The only other accessory I want to add now is a flash light.
