Before we get into talking about AR 15 jigs, let’s clear something up, first. Why bother with an 80 lower? The nicest part about 80 lower receivers is the simplicity in buying them. You can order online, and have one shipped directly to your door. The reason a lot of people are turned off by them is because they need to be milled out in order for the lower parts kit to be installed. The words “gun” and “milling” intimidate a lot of potential builders and turn them away from the 80% DIY route when it comes to AR 15 or AR 10 builds. Whenever we hear people talk about the perceived difficulty in building an AR from an 80% lower, we point them to the 5D Tactical Jig. The 5D Tactical Jig is basically the ultimate AR 15 jig and it’ll turn anyone with two hands, eyes, and a brain into a firearms builder. Literally (and it’s completely legal to do so in your own home, no license required). Keep reading:
What is an 80 Lower Jig?
If you are a new builder and you’re just starting on the 80% lower route we’ll explain jigs. Jigs create the template you’ll follow when you begin milling an 80% finished AR 15 lower. An AR 15 jig is an adaptable device that shows you exactly where to drill, it tells you how to drill, and it gives you a means to finish an 80 lower without any guess work. You don’t just drill and mill randomly hoping it’ll work out – the jig does that for you.
What’s so Great About The 5D Tactical Jig?
There are a lot of great AR 15 jigs out there, but the 5D Tactical Jig comes to mind as one of the best. We suggest the 5D suggest because it really simplifies the entire milling process better than any other jig. You utilize a router and a hand drill over a drill press. The 5D Jig attaches directly to your lower so it’s stable and fits perfectly. Fitment is important because of depth. If you start attaching jigs and they’re just too high you won’t mill deep enough. These little problems can be major pests when it comes time for to assemble – you simply won’t be able to.
The 5D Tactical jig is also the only 80 lower jig we know of that provides a guarantee that it will work with ALL 80 lowers out there. In an industry where you have different types of lowers, and even different alloys and shapes, this is a nice bit of reassurance. One week you may build a billet rifle, the next you may want to build a forged rifle. One 80 lower jig that guarantees you’ll be able to do all, and you’ll be surprised at how addicting milling your own lowers might become.
Smooth is Fast
One of the biggest reasons we recommend the 5D Tactical Jig to new builders (besides simplicity) is because it only takes about 45 minutes to finish an 80 lower if you follow the directions. First timers will likely take an hour or more just to be cautious, but once you have a hang for it you can finish a lower in less time than a NutnFancy video. The 5D Tactical Jig is a simple but robust AR 15 jig that’s perfect for beginners and experts alike.
