anybody know of a good reliable 9mm conversion

a little below AR Discussions there is a thread called "rimfire and pistol calibers", they would know some over there............also look around a bit more in that section.

Quoted: anybody know of a good reliable 9mm conversion

Theres a bunch of great info in the 9mm faq. I just built one last month and it has worked flawlessly.
It's a RRA lower with hy-tech block useing unmodified uzi mags. I used the RRA upper and a mid YHM rail and have already put about 700 rounds through it with out one hicup.

Since we usally on hear about companys that screw us over I will say that the parts I purchased from ADCO, Bravo Company & Brownells we're great as was the service.    

you have your i-m & e-m off.
