Works great. Only problem is the ambi safety doesn’t move correctly but the regular safety works fine. Comes with regular outdoor spring and extra low power indoor spring. I put the Daniel Defense ris II 12.5” rail on it from another older rifle I had, the rail has some wear and is missing 2 screws but works great Comes with original 120/30 mag and 6 extra 60/30 Magpul mags. All have the bolt hold open feature. This kwa is the recoiling one that recoils when you shoot.
