  1. Cliff P. (verified owner)

    Great service. the new 9mm carbine upper/lower is a fantastic piece and having a few extra bolt latch actuary is a good idea. The design is good. Will do more business with Angstandt Arms

  2. Jamie (verified owner)

    I Love the products you make! Love em!

  3. Merovean

    Only bought as a spare as the design seems likely to be a weak link. However it seems to be well made and the original still works so… yeah. Likely good stuff. Love the Jack-9 though really made for a fun build.

  4. Ken (verified owner)

    Lost set screw for bolt catch Actuator got bent make sure to thread locker!!

  5. John (verified owner)

    Shipped to my door in 4 days, easy install, works great and fixed my lrbho issue I was having. Very pleased with my Angstadt!

  6. Cody J. (verified owner)

    Installed on a sharp bros Jack 9 lower. Install was easy and straight forward ( 5 mins total ). Lock on last round appears to be working fine. Will need to run more rounds through the pistol to completely verify the integrity of the actuator.

  7. Trent R. (verified owner)

    I put this on my Sharps Bros. Jack9 lower with an Angstadt upper and it wasn’t working right at first. After getting the Angstadt bolt catch spring kit it works like a dream! Angstadt does it right!

  8. Dennis S. (verified owner)

    Easy to install and very quick shipping, came 3 days early. Works perfect

  9. Scott S. (verified owner)

    Fast shipping and the actuator (with the bolt catch spring) worked flawlessly on my Sharps 9mm lower.

  10. Travis (verified owner)

    Must have for the 9mm lower. Works great!

  11. J.R. Z. (verified owner)

    Works flawlessly. A must have if you’re used to a hold open style of hitting the release on reload drills.

  12. JD (verified owner)

    Solid design and works well.

  13. Doug (verified owner)

    Bought and installed on a Jack 9 lower. Why on earth it doesn’t just come in the box with the lower is baffling.

  14. Eric M. (verified owner)

    Excellent customer service. Top notch parts. Fast processing and shipping’s.

  15. Frank (verified owner)

    Makes sense to have this if your lower doesn’t already have it built in.

  16. Michael S. (verified owner)

    Installed on a sharp bros Jack 9 lower. Install was easy

  17. Robert A. (verified owner)

    Works great so far. Put 120 rounds no problems.

  18. TKT (verified owner)

    Excellent product. Installation was a breeze. (No directions included) Works perfectly.
