4 of 5 5 Position Builder Buffer Tube February 28, 2019
Reviewer: Triston  
Building a 9mm pistol, bought this and the SBA3 Brace. This buffer tube doesn’t allow the brace to lock fully closed. The hole is milled too high on the buffer tube to work with the SBA3. Though it does work with my minimalist stock, just not what I bought it for. Would be nice to see their 8 position design in the 5 position. Missing the numbers on top and buffer detent groove. 5 star if it worked with the brace though!
