Default AR-10 (DPMS LR-308) questions. Please help

I am new to my dpms lr-308 and i am trying to find out if there is a kit or upper or some other method that would allow me to use my new rifle with .22lr. I know that this is not a typical set up for conversion but i cant believe that no one else has done this.
As of now i am figuring that i will need a different upper, some sort of bolt kit, and mag conversion.
Any help would be great.

Thank you,
SH

Also i bought the DPMS model LR-308 but it seems as though it is actually the 7.62 sportical, is there any way to identify the rifle other than the way it looks because the lower say .308 yet the upper (barrel) is stamped with 7.62.

Uhhhhm - 7.62 x 51mm is dimensionally the same as the .308....and there is no such thing as a "7.62 Sportical". The DPMS Sportical is 5.56 only. There are several companies that make .22lr conversions for AR-15's, but NOT for AR-10's. Everything on the AR-10 is much bigger than the AR-15 and hence, nothing is interchangeable. I too have a DPMS LR-308B, and at over 10lbs. in weight, the last thing I would want is to convert it to a .22 rifle...Incidentally, proper protocol when you join a forum is to stop in to the "Introductions" thread and let everyone know who you are! Welcome.

There is a 7.62 Sportical, I think they just came out with them not too long ago. But everything else he said it true. I also have the LR-308B, and it's way heavier than something I would want to convert to a .22.

I know it is what they call the 7.62 sportical i am not sure about when they came out with it. I also im not looking to convert it full time to the .22 i just would like to be able to use it without having to spend the $.50 per round. the principles are all the same with the rifle just alot cheaper to us the .22 round. believe me i bought this rifle in the .308/7.62 because i wanted all that went with having that caliber. i am very excited about this rifle though, i have only put 40 rounds through it and have loved it so far, now i just need more money to spend on it.

You might as well buy a new gun. The conversion is possible on a 5.56 platform, but not .308. The barrel is too big on a .308.

well i have two rifles already chambered .22 so im fine with those, and im not looking to spend alot more. i just figured there are many conversion for many different guns why not this one. its no big deal and as i do some research i dont see any way to do it without a new upper and thats to much money

Default AR-10 (DPMS LR-308) Sportical

Yes there is a DPMS LR-308 Sportical as well as a 5.56 Sportical. I just bought one from Walmart.

As far as a conversion kit, I am looking into that as well, but haven't found anything to date. Colt makes a 308/5.56 convertible rifle which includes a separate upper and buffer assembly and an adapter for the magazine well to accept the 5.56 magazines. But as far as I know, that is the only manufacturer that has such a system. If one could get a magazine adaptor and if a 5.56 upper fit on the 308 lower, and one had a 5.56 buffer, then theoretically, as long as the hammer hit on the firing pin in the right place, then anyone could convert a 308 to a 5.56.

Sorry but you CANNOT covert the dpms .308 to shoot .22 lr . If you want to do that your going to have to go down to the .223 / 5.56 model rifle and use a conversion kit. Sorry but trying to do cannot happen in your current configuration

the colt LE901 which is a 308 can be converted to fire 22lr but thats not the question...
