    Three extra springs one was not even for the AR-15. spring for the recoil buffer was to long and had to be trimmed to fit. The pin for the bolt release was missing. Extra hammer and trigger pins. My suggestion for your kits is to have each assembly, i.e. hammer , trigger , bolt release, capture springs and pins in separate small bags. This would prevent extra parts being included in the master kit and force whoever is picking the kit to verify each assembly has the correct number and type of parts. When the customer receives the kit he /she can quickly verify its contents and leave each kit closed until it is need for installation saving a lot of aggrivation.

    Well the truth is it really looks higher quality but unfortunately I haven't gotten the Lower yet Aero thunder ranch edition . Not available, for much as many items in little supply or low or non production. I am sure it will be just fine when I obtain the stripped lower...if its in my lifetime
