I've been reading quite a bit and just finishing up my first ar15 build. Last of the parts will be in next week and I'll be much happier. I'm wanting to get a 22 conversion for it and eventually convert that to a dedicated upper/rilfe. Is it possible to just use the conversion bolt/kit to build a dedicated up later? I see CMMG listed alot of conversion kits and I assume that means their one of the better ones. Are there others that are comparitively good? I'm looking at ordering some mags to start and hold them till I get the conversion kit. I've seen some stock on the Black Dog mags still out there, are they decent with most kits?

Yes, you can buy the conversion kit and with a collar, use that bolt to upgrade to a dedicated upper later.   Be sure to buy the SS conversion kit.  The Black Dog mags will work as long as you don't care about bolt hold-open.

CMMG make very good conversions and the Stainless come highly recommended.  The 1:9 twist usually give better accuracy than the 1:7 twist.  My 1:9 twist exhibits fliers which will spoil the group.  For CQB drills and for steel plates the conversion kits work pretty good.  Just run a bore snake through the barrel after shooting rimfire and fire a couple 223 rounds to clean the crap out of the gas system.
