............Can you use a piston type upper (ie: ruger sr556) on a standard lower of whatever make?

There are no stupid questions. Only people can be stupid.

Fun-poking aside, you cannot put a piston upper on a standard DI lower. The set-trigger of DI lowers is totally incompatible with the lock plate and frizzen spring of almost all piston uppers.

Thats cruel. You also forgot to mention that he would need to drain the gas from the gas block and gas tube before he swaps uppers out

Ha! JH225, yes you should be able to put a piston upper on a DI lower. A lower is a lower as far as I am concerned and there's no difference, other than the obvious system in the upper.

:) shhh it's a secret haha. He could have found his answer in less than a second with google, so was much more fun to give him a hard time for his lazyness lol.

I'm telling you, if you don't drain the gas the pressurized DI system can leak it's refrigerant causing massive corrosion to the lower sub terminal of the wedge sear. :laugh:

You guys are a bunch of jokers!

You could use a piston upper with a DI lower- If somebody made a DI lower

Ok, in all seriousness, most uppers that folks call "piston uppers" (piston re-located to gas block and using an oprod to act on the carrier) will work with a standard AR lower
