I would amagine everything but the upper?

also how hard is it to install a upper, what kind of tools are needed?

and would you hesitate to build on a ASA lower?

Yes a complete lower is everything but the complete upper. If you have a complete lower and a complete upper, it is just a matter of pushing the pins and dropping the upper on.

If you do some reading in the "Build It Yourself" Forums you can learn a lot. As far as an ASA complete lower goes, well from what I have heard about the companies customer support, I wouldn't use one.

Installing an upper assembly to a complete lower assembly requires the user to close two push pins. About 5 to 6 seconds.

I used to have two of them.  One required some minor (2 minutes) fitting.  Otherwise they were fine.

It's hard to screw up a lower, even for ASA.

I bet if you went down to the shop as long as mean Bob isn't there they would still help you put it together if you had any problems.

I doubt you will because it is bolt on.  Just 2 sliding bolts.  And then you can go shoot.  I don't know where you are at but I am also willing to help you if you ever need it.


So, I gather from all of your posts, you at this point, wan't to buy an ASA lower, and get a good upper from somewhere else.

That's is probably how mine will end up as soon as I get a new job.  I will keep the ASA lower and get a good upper for it.  My ASA upper will become a spare parts platform.
