1911 22LR Conversion Kit

I'm putting together a 22LR 1911 for Bullseye competition.
I've got a Kimber 1911 Custom II which I'm going to use as a dedicated 22LR pistol.

Does anyone use anything other than Marvel Precision units for Bullseye?

Is there anything else available that is as accurate as the Marvel Precision Unit 1?

Thanks,
Tim

Of the .22 conversions that are suitable for bullseye, the Marvel Precision Unit 1s are the most readily available. Advantage Arms or Bob Marvel conversions are equally accurate, but very hard to find.
I would recommend going with the Marvel Precision, as many of us BE shooters are familiar with them and can offer spare parts, troubleshooting, etc.

Thanks for the advice Rob.
That's the impression I got reading the other posts as well.
I placed an order for a Marvel Precision Unit 1 today.
Thanks again.
