Good quality goo price for a lower parts kit to assemble your stripped lower receiver - Aero Precision AR-15 Magpul MOE Lower Parts Kit w/No FCG

Good quality goo price for a lower parts kit to assemble your stripped lower receiver. The only thing I personally change is to cut the safety detent spring to make it smoother, quieter when operated. I DO NOT OFFER THAT ALTERATION AS ANY ENDORSEMENT OF ALTERING ANY PARTS. I also use Militec 1 oil on evert part that moves when assembling the pieces, it is the BEST lubricant I have found, been using it for 7 years.
