Pardon the FNG questions, but I couldn't find the answers offhand...
Do Olyarms 9mm uppers come with a ramped bolt? Also, they will work with any lower with a "standard" hammer, correct?

Olympic Arms uses a std AR carrier, with a caliber specific bolt head assembled to the front of the carrier... Use any hammer. [/blue]
My understanding is that Colt style uppers (in specific, I am looking at the RRA one) require a different hammer and have a bolt is not ramped?

To run the bolt as it comes from RRA, you have to use either a 9mm hammer, or a M16 style hammer with the auto-sear lug removed.
If running a M-16 w/9mm, std M16 parts are used.
If you ramp the 9mm bolt, then any hammer can be used, and eliminates the possibilty of trigger slap.... Myself, I am using the M-16 hammer with no auto-sear lug in my SBR.[/blue]
Finally, does anyone make a magwell adapter allowing a colt system to take Sten mags? (Sorry, my 56k modem won't allow me to read the 10 page tacked post on that topic!)

I use 56K dial-up, and I do not have a problem with the pages downloading,,, it's 8 pages now, as some have deleted their posts. I have the works saved to disc back in Jan-2003. The modified 2 piece Colt style block to use Sten Mags appears to have gotten lost somewhere.....
