Paul,
You said you've got 'em in 6 of your ARs, how do they run?
I thought I read a post (I think it was in reference to the Les Baer Custom ARs) about the McFarlin rings not being as good as the facorty rings or they caused malfunctions or something like that.
Just trying to get more information before I commit to them.

Look for the topic "GOT BACK FROM THE RANGE & LOSING FAITH IN MY AR's"
(about 2-3 weeks ago) I posted this topic, asking for advice on how to get my AR's to function 100% again...
I had installed these Mcfarland gas rings in 2 of my AR's.
Both guns worked "OK" for 5-6 mags worth of ammo. Near the end of my day at the range, I started to notice cycling trouble with the guns. (both of them) I just figured they were dirty after 150-180 rounds of semi/rapid-fire shooting.
So, I took the guns home and thoroughly cleaned them...
The next weekend at the range was a disaster...both guns gave me all kinds of trouble(short cycling & skipping over rounds). I didn't even consider the gas rings because they were brand new...BUT, after advice from folks here at AR-15.com, I decided to install my OLD wore out 3-piece gas rings back into the guns...
Next trip to the range I beat the snot out of both guns and was amazed at the difference in reliability...
gun # 1- (Olympic w/Colt HBAR) 100% reliable 6 mags 0 jams
gun # 2- (Carbon-15) had extracter problems unrelated to gas rings, but NO more short strokes...
(I've since traded gun #2) but have since put at least 300+ rounds through gun #1
with the OLD 3-pce gas rings and still 0 failures...
I think if these McFarland gas rings were worth a shit, the military would have them in ALL thier guns...
They're only $1.75 each, so you haven't much to lose if you decide to try them anyway...
I just had a bad experience with them...
