At my local gunshop, the dealer told me that he gave his military friend an AR-15 pistol, piston driven upper to test out for him at the nearby military base.
And so today I got into an argument with about 5 guys who said that it would not fit, and/ or it would not function. I am no expert but I do believe almost all parts on an M4/ M16 platform are interchangeable with the AR-15 platform, are they not?
If I am wrong, please tell me which parts MUST be changed in order to function flawlessly.
I don't honestly see how they wouldn't, that would be dumb to build a civilian variant of a rifle with completely different and non-interchangeable specifications.
