I have a BCM upper receiver, BCM auto BCG, Gunfighter CH mod 4, BCM 16" mid length barrel, larue tactical 10" free float rail, yhm low pro gas block, gas tube and A2 flash hider. I will be attaching it to a Charles Daly Defense lower with DPMS parts kit and an Magpul MOE stock kit from Spikes with the ST-T2 buffer.
I now need tools as I have never done this before. I want to do it right though. I don't want to skimp out on a tool because it isn't completely necessary. I would only not get the tool if I could do it just as good without getting a specific tool. Some things I am looking for are a wrench that I could tighten the stock nut, free float barrel nut, A2 flash hider and use a torque wrench. Also, which vise block should I get. Spikes? That seems like a good one but like I said I have never done this before and want to do it right. Any other advise will be greatly appreciated indeed. I promise to show it off once I get it put together and plan on taking pictures along the way of the build of the upper as the lower is already done except for completely tightening the stock nut. |

I have used everything here at some time or another working on AR’s.
I would consider the first list as a starter set. I would not call the second list items necessary, but they make life a whole lot easier. This is by no means a complete list of what may be available. For ideas look at the military TM’s and there should be a number of other books available. Also look at the tool kits on Midway, Brownell’s, etc. List #1 Headspace gage set. Action block set. Vise barrel jaws. Barrel wrench. Specialized punch for bolt catch pin. Wrench for tightening castle nut on CAR stocks. Moly assembly lube. (Brownell’s used to carry the ‘mil-spec’ stuff) Any specialized wrenches needed for aftermarket parts like FF forends. 1/2” drive torque wrench. Small hammer with steel head and brass head. Needle file set. Barrel nut alignment gage. Straight punch set. A manual. List #2 Roll pin punch set. Roll pin starter set. Gunsmith screwdriver set with interchangeable tips. Note: gunsmith bits have hollow ground tips that are not tapered. Bit for buttstock screws. Allen tip and Torx tip bit sets. (not needed for AR, but nice for scope mounts) Tool for installing pivot pin spring and detent. 1/4” or 3/8” drive in/lb torque wrench. Socket head allen wrench for carrier key bolts. Punch for staking carrier keys. Fine stone set. FSB taper pin punch. Ejector removal tool. Small machinist level. ETA: I don’t think Brownells carries the moly grease anymore. There was a post in the last few weeks were someone listed an aviation grease he though was equivalent. Maybe a Colt or FN assembler or a current armorer can say what is in use. |

If you have a flatop upper then I see no need for a vise block.. I just use two pieces of pinewood inbetween the bench vise jaws to protect the finish and turn the upper reveiver on its side and clamp the bench vise down..
I have assembled a complete rifle useing the following tools. Most tools you should have? except maybe a Armorers wrench. Obviously Im on a budget, but I dont feel that my rifle is any less superior than someone's who used all the "correct" tools. Maybe its a "Bubba" build??? but on the other Its NOT rocket science either.. Vise grips to squeeze some pins in, use electrical tape to protect finish. Bench vise with two pieces of 1Xpine wood on each side of upper turned on its side. DPMS armorers wrench modified to fit my MI FF tube. RRA carbine stock wrench. small finish type hammer with electrical tape on head to protect finishes. a few sizes of punch sets. High temp wheel bearing grease for the barrel nut. 3/8" torque wrench w/1/2" adapter. allen wrench set.

I went with a seperate barrel wrench and castle nut wrench because when I was looking for tools all I could find were cheap armorers wrenchs. Watch out for these. The dead givaway is too look at the pins for the barrel nut - if the are cast as part of the wrench, walk away. They will bend or break when you start really torqueing your barrel nut. They should be hardened steel pins set into the wrench. Posted Via AR15.Com Mobile |

If you are building a flat-top, this is the best upper block that I have used, much better than the DPMS claw IMHO.
I’ve seen the CLAW break a few uppers. CLICK HERE
