    Great item,Great price,Fast shipping.

  39. Joshua Provost (verified owner)

    It’s decent enough but the detent capture doesn’t sit properly, it’s either to far into the lower and the upper doesn’t shut or you back it out enough to shut the lower and the detent doesn’t sit all the way towards the back like it’s supposed to. Not a huge deal just an annoyance if you have used other tubes that work correctly.

    Quick shipping, no cosmetic flaws. Just what I expected. Side note, last time I ordered I was missing my extra crush washers. Didn’t really care cause they were spares, B Kings saw the review and overnighted them with a ton of stickers! They take care of you.

    Picked the Buffer tube up from BKF for a 9MM PCC build with a fixed Magpul Stock and folding knuckle, Turned out Bass Ace and shoots even better along with the castle Nut from them excellent to do business with. Will be back.

  127. Jeff Rigsby (verified owner)

    Never hurts to have a handful of buffer tubes laying around.
