MP7A1 FPS Reduction "Low Power" Bolt Assembly

"Came in ready to go drop in . Don't forget to grease it up before you put it in so it can slide and cycle smoothly because that's what she said lol jk

"This was one of my best purchases. My KWA GBB MP7 shoots around 350 fps now and I can use anywhere. It is really easy to put in the gun. I would suggest anyone who is looking to buy it to do it.

"I bought this with the intent of using it in my mp7. When it came in the mail several of the crucial springs it needs to function were missing! The springs are cheap so its no big deal. Hopefully no one will have the same problem as me.
