Guntec Complete Lower Parts Kit Features The Guntec USA Complete Lower Parts Kit includes every component needed to finish a stripped AR15 lower receiver saving builders from having to source dozens of small parts individually from multiple vendors. Built to mil-spec dimensions the kit is designed to drop into a standard AR15 lower without fitting issues making it a straightforward choice for both first time builders and experienced gunsmiths assembling multiple rifles. Each component in the kit is manufactured to work together as a system reducing the risk of compatibility problems that can arise when mixing parts from different unrelated sources. Being made in the USA adds a level of quality assurance that many builders specifically look for in their fire control components. A standout feature of this kit is its included ergonomic rubber pistol grip which uses a thin profile design along with a backstrap and finger grooves to provide a comfortable secure hold for a wide range of hand sizes. The grip also includes a built-in storage compartment giving the shooter a convenient place to stash a spare battery cleaning supplies or other small items without needing an additional pouch. That storage feature adds genuine practical value beyond what a basic A2 style grip offers. For builders looking to complete a lower receiver efficiently while also upgrading ergonomics in the same step this complete kit delivers both in a single purchase.
