I have dealt with two. One shot well and one sucked. I`ve had bad experience with EDM. Neither safety worked, one wouldn`t feed worth a crap. Magazine would fall out of gun when fired. I have shipped magazines back and forth and finally said heck with it. I fixed the mag, and remachined the feedramp. The scope base wasn`t a true picatinny as nothing would fit properly. Badger rings, USO anti cant level, and ACI would not work on base. I would look elsewhere.
