AR15 Upper Kits What You Need to Know

1. AR15 Upper Kits What You Need to Know

2. In case you’re planning on building an AR-15 or some other AR platform at home using parts kits, a jig kit, and a lower receiver blank, then you can save a lot of time by getting upper and lower kits instead of buying the parts piecemeal. Here’s the thing: not all AR15 upper kits come with all of the parts you need to complete a functioning rifle. Nor do alllowerpartskits,forthatmatter. At a minimum,here are the parts your AR-15 upper parts kit should come with,whether they’re assembled or not. (Note,somecomewithallofthemandareassembled,andareknownasassembledcompleteupperreceivers). ● Upper receiver (sometimes referred to as a stripped upper if not a part of a kit): This is the componentthatwillaccepttheBCGaswellasalloftheotherpartsoftheupperassembly. ● Barrel: Barrels are caliber specific and come in a variety of lengths. Make sure the barrel you choose is compatible with your cartridge and the rest of the parts of your build kit if it did not come with them. Two of the main finishes offered in AR-15 barrels are stainless steel and chrome-moly-vanadium. ● Handguard: The handguard gives you a place to grip the rifle (since most sporting rifles lack forends)while alsoserving as aplace tomountaccessories. Two of themostpopularoptions are PicrailhandguardsandM-LOKhandguards.

3. ● Gas system (gas block and gas tube): Choosing the proper gas system is vital to ensuring that your rifle cycles smoothly andeffectively. If you buy the blockand tube separately,make sure that the tube is the right length for your barrel and the block is the right size for your gasjournal. ● Muzzle device: Muzzle devices like brakes and flash suppressors are not always included with AR-15 upper parts kits, but if they are you may not need to buy an extra; pay close attentionto thelistofparts. ● Charging handle: The charging handle assists in the manual cycling of the rifle. Not all upperparts kits comewith them. If you see “NoCH,” you’ll need tobuy acompatible charging handleandinstallit yourself. ● Bolt carrier group: This is another part that does not come with all AR-15 upper parts kits. If you see “No BCG,” you’ll need to get your own. Mil-spec BCGs are phosphate coated for corrosion and wear resistance, but there are many other alternatives with high-tech coatings that are harder,tougher,more corrosion-resistant,andoffer betterpermanent dry lubricity.

4. ● Forwardassist: The forwardassist, like theCH,assists inmanuallycycling theaction. Specifically, it can behit to ensure that the bolt is fully forward and locked. Upper parts kits often do not come with these; however, they areaffordableandstraightforwardtoinstall. ● Ejection port door/dust cover: Another part that often does not come with upper parts kits, the ejection port door allows spentbrass toexitthe rifle’s actionwhile serving toprovidea reasonablelevelof ingressprotection againstsand,dust,andotherexternaldebris. This is just a list of what often comes with AR-15 upper parts kits. Remember that this is not all you’ll need to complete a finished rifle. You will also need a lower parts kit, a receiver blank, a jig kit, and any other parts that did not come with the parts kit. (For example, many parts kits do not contain trigger assemblies, pistol grips, or magazines).
