There aren't actually different parts in many ways, but different design features.Įxample: An "Inch" mag catch screw is actually metric threaded & will screw into a Metric receiver, only the description of the part is "inch", its a metric thread, but with a different length & head. Also the "Inch" & "Metric" terms are misleading.

Whole sub assemblies may be interchangeable while the parts within them are not as well. This confuses many people because they don't yet understand what is & what isn't interchangeable. There are 2 distinct "types" the Metric FAL & the Commonwealth (Inch Pattern) L1A1. The first & biggest challenge is going to be getting all parts actually working together!:eek: Also any tips on what tools are really necessary vs. Would really like to keep the whole thing under $1,000, so if anybody has sources on parts kits or receivers that are cheaper, that would be appreciated. It's looking like the cost of the parts kit and the receiver is going to total close to $700 plus another $150 or so in US made compliance parts and maybe another $150-200 in tooling? The goal is to learn something about a new rifle system, gain some basic gunsmithing and assembly skills in military-type rifles, maybe practice some refinishing techniques, and end up with a cool rifle. For the most part, however, this will be an extracurricular project. I'm a gunsmithing student starting soon, so if I run into any major issues I can probably get help from an instructor. If you have done one, what would you rate the difficulty of the build and how satisfied were you with the outcome? I've gone over the concepts a couple of times (it's a little difficult to find good tutorials) and I think I now have a pretty good understanding of the operating system of the gun and what would be necessary to build one. I don't currently have any way to crush rivets or press a barrel, but I can punch pins and I can easily get access to tools to torque the barrel.Ĭurious if anybody on here has any experience in building one.

I thought about doing an AK, but the FAL is a little more interesting to me and it seems like it can be put together with less specialty tooling. I've been looking at doing one of a couple different builds, and the FAL is one recently that's interested me.
