Whats the ar-15.......

You clicked it ....good

Now whats with the AR-15 with a 22lr conversion kit on it?

Ive seen them by Ciener and other known and respected companies, and was wondering if they are harmful to your barrel at all. Do you have to shoot FMJ or can you just buy a brick of regular lead and have no worries. whats the cheapest kit with good reliablity? Is it blow back like 9mm version, or is that just for dedicated uppers? what needs to be changed out for the converion?

Not sure about the Cieners, but the kits I've seen were a complete upper with correct barrel and chamber.

I know they are blowback like a 9mm conversion. I don't see any reason lead would harm the barrel - they arent polygonal rifled. On A2 and newer AR variants I would be concerned with the light 22 lr bullets in a fast twist bbl as it might be too much spin. I've never been able to justify it because for the price of the kit I could get at least 1,000 rounds of surplus 223 or buy a 10/22 rifle. Plus 22 conversion kit mags that I've seen are ridiculously expensive. There's my limited knowledge & thoughts.

M231 conversion units are pretty well out of the Military supply system now.

As stated, you need a 1-14" or 1-12" twist for the LR bullet to properly stabalize.
The units were never that reliable either.

A better option is one of the dedicated uppers built and rifled to properly function with .22LR cartridges.

as mentioned, unless you have an specific need/use for one, such as high volume, lower cost practice with the exact same rifle config. like some High Power shooters seem to want or need, or want an AR that is quieter, or more suited to a younger shooter, there is little reason to get a .22 upper.

and i don't know about now but, back when i knew a few guys who had the kits that replaced the Bolt Carrier group with a chamber insert and blowback bolt assembly (all of them had Colt branded kits btw), those tended to be more trouble and PITA to deal with than they were worth.

in other words unless you have as mentioned a specific need for an AR type .22, spend the cash on a 10/22 or similar and you'll be better served.

Not only that, come SHTF, a .22LR upper will allow you to carry a whole
lot more ammo around, so that you have room in your assualt wheelbarrow
for all that peanut butter and tang.

my intended purpose is being able to shoot at an indoor range. One of the outdoor 100yrd ranges around here is in old bridge pistol and rifle and i have no intention on joining as i have just joined the Navy and will be shipping at the end of september. My friend is a member of OPRC and he is still a probationary memeber which means he EDIT: CAN'T bring guests.

I really just want a 22lr that i can put in my car on a nice summer day, have a nice drive down to Ray's and kill paper. It would be nice if i could get an AR15 lower and 22lr upper, that way when i come back to jersey i can buy a 223 upper and have a blast.

Not a conversion, but Armscor (the Phillippine company) makes a little .22 that's styled "similar" to an M16, called the M1600 (clever, eh?). Sells for $200. The styling isn't perfect from the side, but it does have a carry handle and the stock appears to be close to an AR-15/M16 stock. That might be an acceptable route for a dedicated .22 plinker.

Ok then, for your purposes a lower and dedicated upper are the right way to go. just be aware that you'll be paying aproximately the same as if you were buying a centerfire AR.
