80% Lower Jig | What to Know Before Completion
There are many parts and tools needed to complete an 80% lower. Although there can be some variation in the type of tools you need, there is one that is of utmost importance to have the best result every time: the 80% lower jig. But what is this tool, and how can it help you get the best results?
Think of the 80% lower jig as a template tool. Its main purpose is to guide the builder, giving proper measurements of drill bit holes, and where exactly the milling needs to be done.
They come in many different varieties. Try to stick with multi-use jigs, as they provide longer usability. If a piece has outlived its usefulness, then you can order another of that same plate singularly. There are sticker variations which are meant to stick on to your incomplete receiver.
Jig variations that hook on and give more clear also have features that prevent builders from milling too deep, reducing the risk of permanent damage to the receiver itself. When it comes to milling out the mass of metal on the inside of the receiver, jigs are the best at decreasing the risk of damage.
