DIY rifles - is that even possible?

The AR-15 is a bolt action firearm and has many parts, including upper and lower receivers. Under current law, complete lower receiver must be engraved with a serial number. A complete lower receiver consists of three major parts, including lower parts kit, stripped lower receiver and buttstock. The American lower receiver market is constantly developing. Its products are becoming better quality, more user-friendly, and economically adequate. This part of a firearm can also be partially completed without requirement of serial numbers. These are so-called "unfinished receivers", "80 percent receivers" or "blanks". Buyers do their own finishing work in order to make the purchased receiver usable. Nevertheless, anyone involved in the business as a producer or seller of firearms must get a federal firearms license.

In other words, as long as an individual is not prohibited from possessing a firearm, he or she can make a firearm for personal use. Besides, manufacturers bear lots of specific responsibilities underthe Gun Control Act. These obligations include putting a serial number and other markings on all firearms. 80% billet lower receivers can be considered as a tailored substitute for their forgedanalogues due to their aesthetically pleasing design and good quality. For instance, the leadingmanufacturer in the USA, M1 Machining only uses top quality materials in order to keeptolerances and set a high quality standard.

80 percent receivers are a perfect example of technological advances in corrosion-resistant aluminium alloy manufacturing and construction. Their aesthetic appeal is provided by ability to machine billet aluminium into designated shapes. Billet aluminium AR lower receivers feature durability and functionality. A billet lower receiver is manufactured from a solid block of aluminium which formed from extruded aluminium. The manufacturing stages include milling the AR 15 80 % lower receiver, milling out the fire control pocket, the trigger group and drilling some holes. 80 % AR 15 lower receiver milling process is greatly determined by a milling jig. It is advisable to try it first with a milling test brick before working on a newly purchased AR 15 80 % lower receiver to become familiar with milling the product without risk of spoiling 80 % lower receiver. Completed 223/5.56 NATO Stripped AR 15 lower receiver is compatible with DPMS platform upper receivers.

The Gun Control Act does not control receiver blanks that do not meet the definition of a "firearm" until the builder completes the last 20% of milling. Items being marketed as unfinished or "80 %" receivers are not considered as firearms by the ATF, so they can be shipped anywhere without requirement of Federal Firearms License. However, ATF cooperates with the firearms manufacture and law enforcement to control new technologies and existing industrial trends that could possible impact the safety of the public. The owners of the finished product have to be able to legally own a firearm and remember that the finished gun must meet all applicable laws. And, of course, compliance with all laws is the gun owner's responsibility.
