AR15 LOWER RECEIVER
The LOWER RECEIVER is the singular part of the AR-15 that defines the weapon. By define I refer to the fact that the LOWER RECEIVER is the serialized part of the firearm that contains the serial number and caliber and must be registered as such. The brand of the LOWER RECEIVER is the brand of the firearm with respect to the BATFE and the form 4473.
We are breaking the AR15 LOWER RECEIVERS down into two categories. The categories are STRIPPED AR15 LOWER RECEIVERS and COMPLETE LOWER RECEIVERS.
STRIPPED AR15 LOWER RECEIVERS
STRIPPED AR15 LOWER RECEIVERS are as their name implies, bare receivers with absolutely no parts installed. This means you will need to buy a LOWER PARTS KIT, PISTOL GRIP, BUTTSTOCK, BUTTSTOCK EXTENSION TUBE and RECOIL or BUFFER SPRING.
The proper AR15 TOOLS are also needed for installation of the above mentioned parts.
COMPLETE AR15 LOWER RECEIVERS
COMPLETE LOWER RECEIVERS are typically available in two varities. The first variety is a truly COMPLETE LOWER RECEIVER that has all the parts installed and is ready to accept the UPPER RECEIVER of your choice. The second variation typically only has the LOWER PARTS KIT installed. This is a nice option for shooters who either dont want to buy the ar15 tools or those who dont want to risk damaging the finish on the LOWER RECEIVER. The ROLL PINS can be tricky without ROLL PIN PUNCHES.
There are some variations that omit the BUTTSTOCK and associated parts. They are neither stripped or complete but they do exist.
