| How hard is it to do a build from a 40% receiver? What exactly must be done and what tools must I buy? (I have a machine shop, but I meen, what special taps & dies must be bought for special cuts on this) |

Do you have a known good receiver to use so you can reverse engineer it? You will need one as there are no complete prints out there. There are a couple of guys on the falfiles who have finished a couple of receivers and I started one but changed jobs so no longer have unlimited access to the machines like I used to. I have to heat treat mine and finish the rails, locking shoulder hole and extractor cut still. All my tooling is in storage right now or I would look it up for you. I know I had to buy 3 keyway cutters, the tap for the barrel, gas tube, and reamers for the locking shoulder. |
Sadly........no.  I traded my FAL for a Ruger Redhawk before the end of the ban because I hated the thumb hole stock and didn't believe I would ever be allowed to change it (I loved it other than that). I'm one of those guys who just can't see going though a dealer to buy a gun anymore. With the cheap kits on the market I started dreaming of building a FAL. Can you just give me an idea of what all must be done to finish a 40%er and build up a FAL from there? I still may hourd a few just incase I find one to reverse enginer off of. |

You need to finish the inside of the receiver to size. Cut the rails for the bolt carrier and dust cover (2 key way cutters for those cuts). Cut the slot for the charging handle and cut the rails for it also (3rd keyway cutter. Thread the barrel and gas tube holder. Locking shoulder. Overall length and outside to size. The locking lug for the lower receiver. Hinge pin hole for lower. Extractor cut. Install ejector block and pins. Heat treat at least the locking pin area and barrel thread area. I am sure there are others things I can't remember but those are the major things. With out any good prints it really makes it a long drawn out project. I have 3 receivers to go off and not even the 2 made by the same company are the same. I spent more time measuring and double checking then I did actualy cutting metal. Since it is a casting it is pretty close to size in a lot of areas so there is little heavy material removal required. |
