Good lower parts kit - CMC Triggers Complete Lower Receiver Parts Kit for AR-15

I’ve bought this lower parts kit before and have had no problems. The parts are to spec and work appropriately. They dont have any sort of non-standard finish or extra polishing, and they come loose in a plastic bag. Other more expensive kits have each individual part sealed separately and labeled (or have different coatings that are largely just for looks and not functionality). The lack of labeling may make a difference to you if it is your first build or you are unfamiliar with the different parts that make up a lower parts kit. Either way, there are plenty of other resources out there help you assemble a stripped lower, small parts labeled or not. For the price and overall serviceable quality, you should have no concerns about buying this product.
