    Great deal

  2. Jake (verified owner)

    Great set, especially for the price! Everything fit perfectly (and easily) into my Aero M4e1 build. The trigger is also pretty great and has an easy pull/ break. I’d definitely buy this set again and most likely will for my next build!

  3. Jefferey P. (verified owner)

    Awesome kit, everything went together buttery smooth.

  4. George F. (verified owner)

    All components were to spec! Perfecto!!

  5. ronflowers1022 (verified owner)

    Sound components that met specs! I had an extra Aero Precision set I didn’t need to use on my Aero
    pistol lower.

  6. Scott (verified owner)

    Installed on an Anderson lower. These parts fit perfectly! Quality was good. Buffer tube has a nice finish. I use an SBA4 pistol brace which tends to be hard to slide, but on the buffer provided with this kit, it slides nice and easy. A+

  7. Robert barbier (verified owner)

    Worked good

  8. John Tellen (verified owner)

    Works fine

  9. MARK U. (verified owner)

    Went together easy with my M4E1 receiver and worked out with my SBA3 that I bought without a buffer tube.
