ive prolly run over 5k worth of 22lr through my cmmg conversion in my colt sp1. i find it easy to clean. wipe down with breakfree. the bullets from 22lr kinda rattle down the barrel havent had a bit of leading issues as i dont fire centerfire rounds through it before cleaning.

accuracy seems to be solid 3"inch groups at 50yds with colt 4x scope. it eats everything including crappy remington bulk packs works. havent found anything it wont cycle. only stoppages ive had with it have been rounds that just wont go bang and have to be tossed.

wouldnt mind having a dedicated upper, but i dont see the need.

Just be sure to fire 2-3 223's for every 200-300 rds of 22lr, to make sure that any 22 residues are blown out of the gas tube.
What kind of .22 upper is it?

Default Colt/Umarex & Cmmg Sierra Upper

Maybe I'm just lucky but the Colt/Umarex 22 has been great and my grandkids love it. The trigger is a little rough.
I also bought a CMMG Sierra Upper. After some teething problems (the bolt rear plate fell off!) It has worked pretty well. I get an occasional flier and wonder if the spring is strong enough. Mated to a RRA lower, with a good trigger the CMMG is a ball.

your welcome. one last thing dont let it sit with the 22lr dirt in it for even a day and keep it well lubed while shooting the 22lr stuff. heavy lube prevents a lot of the caking of the dirty as hell 22 ammo.

I do find if we use the 10 rnd mags we tend to save ammo. Something about running 10-15 rnds out of the 30 and then wanting to "open 'er up" really results in you opening up the wallet!

I really recommend a dedicated rimfire AR. I don't like the idea of running a lubed lead bullet past my gas port on my 6940.

X2, and dedicated.

And as far the Colt/Umarex M4 22, I've been running tactical carbine drills with it since February, and it's a mighty little tack driver. For simulation it is almost identical to the M4...never a misfeed...oh, yeah, wait a minute, after a few thousand flawless rounds, we had ONE misfeed because somebody had loaded a mag with Remington

Hmmm, four of us here actually own the Colt/Walther/Umarex .22LR and all four love it. What are the odds of that after reading all the negative opinions in the wind. Guess we must be lucky bastards because the internet ninjas all say it's a piece of junk! No doubt the S&W M&P15-22 - and probably most of the other military look alikes are fine choices as well.

Anyway, I vote dedicated over .22 conversion if you plan to run a lot of ammo down the tube. And if you want the accuracy a slow barrel twist will give you.

I think its the "gotta have the best of the best or its not worth crap" crowd you find on the big forums. Sometimes the wealth of knowledge on the internet is a hindrance. Its hard to know who to trust. But then how many of us have the $ to experiment w/ what works and what doesnt? Its an expensive hobby and theres always something I "need" so every penny counts.
