Nice quality parts kit with one oddity
This is my first AR build and was reccomended by a local shop to try this new parts kit from DoubleStar that he had seen on Brownells. Promptly ordered, shipping was fast and parts kit included an extra detent and detent spring for the takedown pins. The trigger is smooth with very little to no play and everything fit perfectly except for the rear takedown pin. It was slightly large diameter such that it would not go into the hole at all AND it was not machined with the detent groove. Seemed kind of odd so I took it to a gunsmith who checked measurements of my Stag lower reciever (perfectly within specs) and the pin and indeed the pin was a few thousandths oversized not to mention the missing detent groove. I needless to say had to purchase a separate rear takedown pin to complete my build. I suppose it could have been a mistake on Double Star to place the wrong part in the bag, but overall, I'm quite pleased with the kit.
