    My go-to parts kit from my go-to online source, always a COMPLETE set, oil coated and ready to build.

    Great standard parts kit

    Posted by Aaron on Aug 22nd 2018

    LPK does the trick. Fits perfectly into the Aero lower I purchased and has a better than mil-spec feeling to the trigger. Will be my go to kit from now on.

    Best Quality and springs...

    Posted by Rob in Sav’h on Jul 4th 2018

    Building an aero Percision lower and this kit has just what was needed, rear takedown pin detent spring on arrow receivers is a fairly tight fit with other parts kits... this kit however has the correct spring size and no doubt I will be ordering more. Just what I needed when I needed it. ⭐️⭐️⭐️⭐️⭐️

    Aero Precision lpk

    Posted by Tristan on Jan 28th 2018

    I love these lpk kits. They fit the lowers with "precision" fit. The triggers (fcg) are usually smoother than what you find on the PSA, Delton and factory built basic ar15's.
