    D.Mighty where did you obtain this information. I am intersted in this as well. I would like to know for sure since I am buying an le 6920 tomorrow or the next day. If there are so many options available and the chamber can mathematically and by design support the different brass and calibers why do we not hear much about it. I would totally love to figure out how to shoot cheap 9mmx19mm pistol rounds through it. But how?

    Ill send a PM. I do not want to go public out of respect for my friend/dealer. I will tell you that there are about 3 gunshops in Atlanta Area that have 6920s and at least one that had a 40 but I guarantee it will have been sold by the time you read this. Some people like that hand grip and flat top on that 40 model.

    Here are my future mods Im going to get over the next 2 months or as available.

    Some bulk packs of Milspec 5.56 - It's a colt after all.. she'll take it.
    A few magazines that I already have from the military.
    JP VTAC 9" smooth grip (use only the rails I need)
    CMMG .22 conversion bolt, but subject to a ton more research first.
    Green laser - gotta find which one I like or the guys/girls here recommend.
    Taclight - Streamlight or surefire
    Urban-ERT 1 point AR tactical Sling or something you guys recommend
    Standard everyone gets EoTECH red laser dot sight.
    Sometime in the future a regular luepold scope for deer hunting or long range shooting.

    Just a note about the various .22 caliber conversions out there.

    Some are good and some are not so great. If you buy a conversion kit, you will only achieve mediocre accuracy from the .223 barrel because the twist is not fast enough for the shorter,slower .22 bullet.

    For the best accuracy on the AR platform, you must buy a dedicated .22 AR upper. This will consist of the whole top half, complete with bolt and the proper twist barrel for the .22 Long Rifle.

    Most of the dedicated uppers will out shoot the drop-in-bolt conversions kits.
    If you aren't too concerned about accuracy and 2-3 inches at 50 yards is good enough then the drop-in- bolt kits are fine just for plinking.

    If you want some good accuracy, around 1/2" at 50 yards, then you need to get the whole top half.

    Interesting. Do the .22lr uppers also have a manual of arms identical to a normal AR? One annoying thing about conversion kits is that everything is not functional (bolt hold-open switch?).

    If you're going to spend the money and get a dedicated upper, in my opinion, you might as well just get a AR in .22LR caliber.

    I think S&W just came out with one. I don't know who else makes one, but I'm sure that S&W isn't the first company on the block to do so.

    Just the opinion of an arrogant fool that resembles the south end of a northbound mule.

    I purchased the .22 LR conversion upper for my Glock. I like it, but one issue I was very aware of was the for the price, I was close to being able to purchase a deticated .22 LR. If I'm not mistaken, that cost ratio increases far more ($600+ to $1000?) when you deside to go with an AR-15 .22 LR conversion or deticated .22 LR on an AR platform. I have often wondered why the best option would not be to just to get a Rugger 10/22 with an AR like conversion.

    I've also considered purchasing a bolt action .22 LR so I could practice the basics, without the recoil of my 30.06 hunting rifle. Just feels at some point the basics are the basics, and you can learn just as much with a deticated .22 LR semi-auto as you could the conversion kit for the AR-15.

    I have an AR-10 and wouldn't consider a 308 as a home defense round. It will easily penetrate several walls including brick siding and keep on going. Mine is for hog hunting and for SD when SHTF but certainly not a home defense gun during normal times. You'd be better off with a 223 for home defense if you are looking for an AR IMHO.

    I purchased a .22 conversion bolt for my ar-15 and couldn't be happier. Yes the accuracy isn't as good, but for $200 you can't go wrong just to get the trigger time.

    I have 4 AR15s I built all of them, it was cheaper to do them about 5 years ago, I believe they came out to about $400 each to put together. I also got 2 of the M261 kits and 4 mag inserts for $70. I also built 2 FALs 7.62x51, so I never considered buying an AR 10. I would say to start with the AR 15 then buy a AR 10 later.
