    Fit and function were great on my Anderson lower. Fast shipping as well.

  2. Michael R. (verified owner)

    Great value & fitment. Trigger is very smooth.

  3. Brian (verified owner)

    I rated a 3 could’ve easily been a 5. The price and shipping time was good. The product was good quality but…when the package arrived the LPK was crammed into a small bag that had been torn by one of the sharpe edges. So I had springs and detents floating around in the package. I was able to locate them all but could’ve been a real downer.
    All that said the parts are assembled and work as promised.
