It’s easy to be overwhelmed by the volume of tiny parts that need to be collected before you can assemble an AR-15. You can buy parts kits, but then there’s the inevitable guilt you have when you want something specific that’s not included in anyone’s AR15 Build Kit. You’ve invested enough in this rifle that you can’t quite look your kids in the eye already. Now, you’re going to put new parts on the shelf and buy upgrades before you’ve even finished the beast? There’s a better way. Choose a quality Lower parts kit from a manufacturer you can trust. Armaspec’s Gun Builder’s Lower Parts Kit less Trigger Group and Grip comes chock full of high-end parts but leaves out those you’d rather choose individually for your dream rifle.
