Quantity in Stock: RTB Upper Build Kit 16" .22LR Upper Receiver - Black | A2 | 15" M-LOK | With BCG & CH
This build kit DOES NOT come assembled.
This Complete 16 inch M-LOK upper receiver build kit comes with a 15 inch free float handguard and includes only the best Mil-Spec components for your build. The core components of this kit are a barrel that’s machined from chrome moly vanadium 4150 steel, an M4 upper that is machined from 7075 T6 forgings, and our bolt is made of all stainless steel construction and we use an anti-jamb dedicated 22 charging handle.
As a “do it yourselfers" or DIY enthusiast, you may prefer an AR-15 build kit over a complete upper. Building an AR-15 from a kit allows for a greater level of customization and personalization of the final product. DIYers can choose from a variety of components, such as barrels, handguards, and triggers, to create a rifle that meets their specific needs and preferences. Additionally, building an AR-15 from a kit can be a rewarding and educational experience, as it allows you to gain a deeper understanding of how their firearm functions and how to properly maintain it. Building an AR-15 from a kit may often be more cost-effective than purchasing a complete upper, as it allows DIYers to select only the components they need, rather than paying for pre-assembled parts they may not want or need.
We also carry this Upper Receiver Kit assembled here.
