A lot of times I am asked about the parts that make up a rifle build, so I am revamping a series of “Build Breakdowns” that explain what parts were used to put a certain rifle together. Each part or grouping of parts will be listed below the image and will be hyperlinked to the Rainier Arms website, or another site if not available on Rainier, where you can learn more about the parts or to make a purchase.
This build focuses on a Primary Weapons Systems Build that I recently put together. The build started as a separate upper and lower receiver set that were mostly complete from the factory.

Fathom Arms has been generous and are offering an exclusive coupon code for their Nitride Full Auto Enhanced Bolt Carrier Group (E-BCG). The E-BCG retails for $174.95 and with the $20.00 off coupon code brings it down to $154.95.
LanTac USA, who has been mostly known for their Dragon Muzzle Brakes, had a booth full of new awesomeness available for all to see….and for one sticky fingered thief, a BCG to take home.
LanTac USA’s Blast Mitigation Device, or BMD, is a removable shroud of sorts that can be placed over the Dragon Muzzle Brake to control the side blast from the Dragon and away from the shooter. The BMD is quickly removed from the Dragon by pressing two release buttons on either side of the device.
This Enhanced BCG is the brother of the Ti Enhanced BCG that was stolen from the LanTac booth at SHOT. The stolen version was a one-off version without Forward Assist serrations and was made of Titanium. Click HERE for more info from LanTac regarding a description of the stolen BCG. They are offering a reward.
The Enhanced BCG is M16 Full Auto style, machined from 8620 steel with a Shot Peened (SP) bolt and is Magnetically Particle Inspected (MPI). The entire carrier assembly is NiB, electroless NiB coated with the patented advanced UTC EXO process. The carrier features forward gas porting with enlarged gas vents to run cooler and cleaner and reduces the pressurization of the receiver.
The LanTac Gas Block will fit .750″ diameter gas pad barrels and uses two set screws to secure the block in place.
The LanTac USA SPADA-S Rail is a lightweight freefloat handguard that features reinforced attachment positions at the 3, 6 and 9-o’clock positions with helicoil inserts. The rail offers zero protrusion to the rear and will mount to any upper receiver, regardless of shape.
LanTac USA Upper Advancd Receiver (UAR)
The LanTac USA Upper Advanced Receiver, aka UAR, is machined from Billet 7075-T6 aluminum, is finished with MilSpec, Type 3, Class2, Deep Black, Hardcoat Anodizing and comes standard with M4 feedramps. The UAR comes standard with a CP-R360 Domed Head Cam Pin. The Cam Pin features a circular head with singular flat face so it can retrofit any other BCG cam pin without the need of removing the gas key.
Fortis Manufacturing has recently released two pieces of pure epicness; the Fortis Billet Upper Receiver and the 5.56mm SWITCH Rail, which is currently offered in the 12″ length.
FORTIS BILLET UPPER RECEIVER
Sticking with the sexy lines that Fortis has become known for, the Billet Upper Receiver is no different. Not only has the design been amped up, the weight has been shaved down without loss of strength or rigidity in this upper machined from Billet 7075-T6 aluminum.
The SWITCH Rail, which was originally reserved for the .308AR Platform, was expanded to the 5.56mm Platform after such a positive reaction. This lightweight rail is by far the easiest rail install of all time, so much so, it is easier than replacing a set of stock plastic handguards.
New from Mega Arms in 2014 is their new Megalithic Tactical System that is available for both the 5.56mm and MATEN (.308AR) platforms. This one-piece upper receiver and rail system will be available in Mid and Rifle lengths for 5.56mm and Rifle length for the MATEN. The Megalithic Tactical System incorporates a strategically integrated level system and the Key-Mod versions come with hardened QD sockets on the rear sides of the rail.
Aero Precision has introduced several new products for 2014. Building off of their successful COP (Continuous Optics Platform) monolithic upper receiver, Aero Precision is now offering a gas piston compatible COP Upper for the AR-15 in carbine and mid-lengths and are in the process of working with Adams Arms to offer a package including the COP and the piston kit. Also available later in 2014 will be a COP Upper in .308.
