I was sent the wrong item. nice quality though - Dead Foot Arms Modified Cycle System 9mm Bolt Carrier Group (BCG) w/Left Side Folding Stock Adapter

I ordered the 9mm mcs by dead foot from Optics planet. Opticsplanet sent me the wrong product. After some closer observation i noticed the packaging does say 9mm. However, the bcg is obviously the rifle version. After an even closer look on dead foots website i noticed that the springs are also color coded for the rifle version. Its a real bummer because i spent hundreds of dollars to build around the 9mm version. Now i will lose credit for the bonus bucks i used when i have to return all this extra unnecessary stuff. I wish i would have received the right product i would be writing a 5 star review. Dead foots quality is unmatched especially the folding adapter. Its not even close I really couldnt recommend them enough. I was sent the wrong product and im probably going to be keeping it. Thats how good it is.
