Build your own AR-15

Build your own AR-15 from scratch

by on February 12, 2013

If you’re looking to build your first AR-15 or even if you’ve already built one, this video will provide you valuable tips, tricks and insight into the How and Why of building and maintaining your AR-15. I scoured the web – forums, YouTube and major retailers for info, and there is tons of it out there. The only problem is that you’ll spend lots of time trying to figure out what is good or bad practice, especially if you’re new at all this AR-15 building business. Well, look no further, because this DVD puts it all together for you using a Master AR-15 Armorer as your instructor. Unlike a major web retailer that offers free videos and trying to sell you tools and gadgets, this instructional DVD spends more time on the How and Why you need to do the things you do when building your AR-15. I highly recommend you give this DVD a chance – you’ll be glad you did. You may also want to pick up a copy of the M4 Carbine M16A2 W/E Armorer’s Guide by Desert Publications as a reference resource after your build.

Here’s a breakdown of the DVD Chapters:

Intro - This is an brief intro to the AR-15, the extensive background of the instructor, and what the DVD will teach you

Opening Comments - a conversation with the instructor discussing major components/quality/choices, discussion of the lower receiver and what to look for in a quality lower receiver, how to select a quality lower parts kit and a detailed explanation of all the parts in it

Lower Receiver - detailed explanation of the assembly of the lower parts kit into the lower receiver, the sequence of parts installation and why that sequence is important, some specialized tools (and how to make them yourself), other tips and tricks, what to do and what not to do and why, alternate methods to install roll pins, installation of buffer, spring, butt stock.

Upper Receiver - discussion of the different types of uppers and how to decide which type to select for your build, an explanation of the basic parts needed for the upper receiver assembly and their function, whether to buy a built upper or a stripped upper and separate parts (ejection port assembly, forward assist parts), how to install the parts, he also explains the use of an upper receiver vise block if you have one.

Barrel/Gas System - discussion of barrel types/prices and how to choose one, determining quality, barrel length, rate of twist, accuracy determinants, discussion of gas systems/lengths, A2 FSB discussion, barrel extension timing explanation, explanation of the bolt carrier and function with the barrel, checking the crown of the barrel, muzzle brake/flash hider sizing/selection, specialized tools to drill the gas hole and install an A2 FSB (taper pin explanation) and hand guard ring if you don’t buy a completed barrel, detailed barrel installation, gas tube installation, muzzle brake timing/installation, hand guard installation

Bolt Carrier Group - explanation of bolt carrier group (BCG) and gas system operation, BCG function with the barrel and assembly/disassembly, extractor inspection/cleaning, BCG gas ring replacement.

Gas Blocks/Final Assembly - explanation of different types of gas blocks available, discussion/installation of Magpul MOE Handguards, discussion/installation of free-float handguards, final assembly of charging handle, bolt carrier group and upper receiver to lower receiver. Enjoy your new AR-15.

The video gets great reviews and feedback on Amazon with 4.5 out of 5 stars from well over 50 reviewers! At $19.95 it’s a steal.

Buy the DVD, you won’t regret it.

Important: make sure you are aware of your state laws as there are quite a few state restrictions on owning an AR-15 in California as well as other state restrictions on things like stocks and flash hiders/suppressors. Under federal law, the Lower Receiver is the only serialized part on the AR-15 and the only part that is considered a firearm. This means that the ATF requires the buyer has a Federal Firearms License or uses a licensed FFL dealer to conduct the transfer of the Lower Receiver from manufacturer/distributor to buyer. Form 4473 will need to be filled out and most FFLs will take care of this transfer for you by charging a fee, commonly refered to as a “transfer fee.” This can range from $25 to $75 depending on the dealer. It never hurts to call around to your local dealers and find out if they deal with FFL transfers and what they charge for transfer fees. Just always use a reputable dealer! An exception to this is if you’re buying a lower or firearm from a private individual who isn’t a licensed dealer, in this case you DO NOT have to fill out a Form 4473.

When it comes to buying the parts for your AR-15 you also need to tread carefully. There are many AR-15 kits on the market, but the sad truth is that for most of these kits the are made from subpar – reject components from major brands. In the manufacturing process, there’s always parts that are out of spec or do not meet quality control standards and so they are rejected and other Companies buy these parts up and use them in the cheap AR 15 kits. So buy a kit from a reputable brand.
