  1. Not happy with this cheap over priced brace it’s very wobbly and wanky to say the least. My friend ordered a Chinese one from alibiba it fits better and looks identical for a quarter of the price.

  2. Do you need to replace the buffer tube if the gun already has one on it? Example-I have a MK18 with the SOB on it and I want to swap that for the SBA3 or SBA4. Can i just pull the brace off and replace it or do I need the brance and buffer tube?
