Unless you are really worried about the "dancing horsey", save your money and buy an ASA or RRA. As a minimum, you will need a 9mm upper assembly, and a mag adapter of some sorts.... If you really want to go cheap, buy a barrel blank, machine the chamber end to fit the upper, chamber it, and shoot it using a scope or dot. Front dimensions are optional>> no gas system to worry about... My SBR 9mm barrel from blank.

What is the difference in your "conversion kit" for $750, and the complete upper for $450, add $150 for the block?? Does the upper come with a bolt? That is the only reason I see it being cheaper.. You will nedd some kind of upper, and a way to hold your mags.[/blue]
I understand that I need ot have the bolt shaved, so I can use my standard AR hammer.

I would like some recommendations, and suggestions on other work that needed to be done? Although this is only a practice only conversion, I do like to have a combo that is free from functional problems, and field accuracy (2 to 3 MOA).

Read the 9mm threads here and in the "AR General" forum. Advise you remove the extractor from the bolt, and use a sized case, or a loaded round to visual the headspace, as the extraction-ectractor grab are dependant on correct dimension. This thread is made to sound a lot worse-harder than the problem is to repair, I simply had my barrel "faced", and set back to repair my problem, joe is working the right idea, but from the wrong end I feel, but it HAS worked for him.
