AR15 build--what tools are required?
Thinking about an AR15 build. Maybe a varmint type build, flat top with a 20" barrel.
What tools are required? I know I'll need a barrel wrench ( multi tool ). What else? If "soft" vise jaws are needed, I can make them Suggestions on who has good prices on good parts would be appreciated too. Thanks |
How in depth will you get? Are you going to do a custom barrel and mate it to the receiver? Unless it is just something you want to put together yourself, it is still really economical to buy the barreled assembly already put together.
You will need a spanner wrench for the buffer tube nut. They are cheap online, or your gun store may have them. I use a brass punch for the dowel pins (painters tape on the receiver to avoid marring) and a small hex key to hold the bolt release latch in place as you drive in the dowel pin. An Xacto knife or a plain ol' one sided razor blade to put the forward take down pin detention spring and detent pin in place. Trust me, if you are not careful with that one, it will shoot across your work area/house like a rocket, probably never to be found again. |
Sounds like the assembled barrel is the way to go.
I did a FN-FAL ( L1A1 ) build a few years ago, that worked out great, this is new territory so I'm asking questions. :yesnod: The wrench is about $20 on ebay, I'll just grab one now so I have it when I start the build. |

Installing a parts kit into a lower is a piece of cake, no tools required that you wouldn't already have. As James mentioned, just buy a ready made upper, no reason to assemble that.

Whether or not you assemble from parts or purchase subassemblies get the barrel wrench and a receiver block to go in the mag well and in your bench vise. I find working on most any part is simpler if the weapon is securely held and I do not need to hold it with one hand and wish a buddy was here to hold the punch while I tap on it. The investment is small, and if you decide to change handguards, or change calibers or build several because you will want more than one you will be equipped.

I have a 20" barrel on my Bushmaster DCM, maybe I'll go with a 16" or 18" :confused5: |

I might recommend starting small and light... 16 inch "pencil" profile barrel, all polymer furniture and collapsible stock. Your choice of A2 upper and front sight or A3 upper (flattop) and the open or optical sight you prefer. The result will be a lively handling easy to carry piece which is fun to shoot and collapses short enough to be easily concealable, and will work OK (in a pinch) in a vehicle. Target weight is 6 pounds sans magazine or optic... the Mrs. will like that too!

I am near Hazleton, PA. I can loan you whatever tools you need if you wanted to pick them up. I have an armorers wrench, mag block, and roll pin punches. If that PSA set is the premiun set with the FN CHF barrel, go for it. I like Aero Precision components myself. Not much more when on sale.

Just waiting for my armorer's wrench to arrive and it'll be assembly time :hurray:
The lower is a blem. On the inside of the magazine bevel is an extremely small mark ( like a slip of a file ) that Aero Precision deemed to be an imperfection. That saved me $27 ( almost a third ). Pricewas $63 :yesnod: The lower is forged 7075 aluminum :cool1: |
I highly recommend a Larue trigger. I have one in every build. The best $87 you will spend on an AR. The bolt catch roll pin is the only tricky one. I use the starter and punch built specifically for this with one side flattened. I also tape the area on the receiver. I use some 220 grit sandpaper on one end of the pin and some Oil. I can usually get it in pretty far and then I use a set of straight jaw tongue and groove pliers wrapped in electrical tape to pull it the rest of the way through.
