It will work.

You should install a heavy 9mm buffer.

Possibly have the bolt ramped so you do not damage the lowers.
(KNS Pins also availible)

What kind of stock are you using, fixed or collapsing? If it's the fixed stock, you'll be fine with the original buffer. If it's a collapsing stock, the heavy 9mm buffer would be a good idea to make the gun more pleasant to shoot and reduce the abuse on the lower. It takes all of ten seconds to change over.

Well, the heavy buffer takes more energy for the bolt to move the same distance, so you have less energy transfered to your hammer, hammer pin.. etc...

A buffer takes less than a minute to exchange, and you will not damage anything by doing it.
