AR15 builders have a number of 80 percent lower jigs to choose from them but they are generally broken into two popular categories. The jig that’s most popular are commonly known and offered the most 80 percent lower manufactures was the drill press jig. The second one commonly known, but more superior then the router based jig.
Drill Press Jig
One of the hottest drill press travels takes a designer to utilize both the mobile drilled gun, or drill press in order to complete the lowers. The jigs guide contractors in going upwards for 42 distinct holes, into quality making the Swiss cheese effect. Few drill press lower begins the positioning process through utilizing a smaller drill bit such as 1/8 inches touch and after then graduate up to bigger touch such as 3/8 inches. The method of going to develop 42 unique drill holes eventually carves out to fire controls wallet, enabling you to you can add your lower parts lure set. Like all 80 lower jigs package, this drill press jig allows to 3 horizontal holes to be drilled in to the sides of the lure to accommodate the fire or safety selector switch, along with trigger pin along with the hammer pin.
Also 2 types of drill press jigs available in the market .First one is the Rugged 80 percent lower Jig and the second one is Tough AR15 lower receiver Jig. Both works certainly flawlessly job done but they vary in their quality, durability and price offers.
The router jig products change from the punch press travels in this it requires 2 kinds of machining. The Heavyduty 80 percent lower Jig begins same to the drill press in that’s you still need to developed Swiss cheese but it requires low less drilling. The router based approach simply requires one to produce around 10 drilling holes, less than 25 percent of holes required with drill press travels. Then next thing is time savings is. After the Swiss cheese have been designed, then it time towards the nice end mills bit and switch. Using trough handheld switch, then your designer makes pass, next pass jumped to and from each of the past drilled holes. Applying that router, the contractors make 6-11 distinct moves to finish to the trigger pocket.
The Supreme 80 percent lower Jig kit was the most expensive. Whatever the strength durability’s and its speed make it the most decent option. Using the router based jig systems, a builder can machines lower in 1/2 of the time and completed into the 20 different lowers.
