An 80% lower receiver blank or frame is an incomplete firearm that needs to be milled out Because of this the ATF does not recognize any 80% lower as a legal firearm Meaning that you can have it shipped directly to your house without a background check If a percent lowers are great for people who want to make their own builds uniquely and fully customizable. The AR-15 is one of the most popular 80% lowers out there being machined and produced by many companies around the US. According to the ATF the only part of the AR-15 lower receiver that is considered a firearm is his arm is the port for the trigger. This is what you will need to mill out properly in order to create a fully functioning firearm The AR-15 platform is highly modular and diverseThere are a few modifications to the platform which make it able to take either rifle cartridges or pistol cartridges. These are the .308 DPMS lower and the AR-9 lower respectively. All 80% lowers may be shipped right to your address.

Slide is smooth, upper parts were not too hard to install, and lower came out great, I used my drill bits, rather than one sthat come with P80 and fitment was much tighter and whole build came out very durable. 4 Pretty Close to G19 Posted by Samuel Chappell on 03-08-22 It's not Glock but it sure is close to one.
