Well, I know on a lot of rifles all that's needed is to shave down the sheer pin. That's the quick & ILLEGAL way.Baring that, he's correct....you would have to replace the entire mechanism.

This is incorrect and dangerous. Only three rifles can be modified this way and by doing so, you create what is called a slam fire situation.
The anti's would love to have everyone believe your statement though...

That's an old wives tale. What would happen is the firing pin would slide into the primer. The firing would be haphazard. In a nodern inertial firing pin system you would get nothing. To operate effectively, a fully automatic rifle employs a delay system in which the pin hits the cartrige after the breech is closed and locked.

The illegal part would be the least of your worries. Altering only the sear would most likely cause the firearm to fire out of battery. It is doubtful you would survive the magazine with the types of rifles discussed in this thread. Due to a mechanical failure, I faced a similar situation with an out of battery round that resulted in a catastrophic case rupture (I am very lucky to still be able to count to twenty one!). Mechanically speaking, none of the rifles discussed are readily convertible without the parts specifically made for fully automatic applications. Given the number of machining operations necessary to make these parts, I'd rather build up a new firearm from scratch.

The problem with filing down the SEAR pin is that there is no select fire capability. It'd be easy for the weapon to go full auto and be out of control...a runaway gun so to speak that would only case fire when it ran out of ammo. I once saw a gov't model 45 do this on a range. The SEAR was naturally worn from excessive use and not much preventive maintenance. Suddenly WHAMWHAMWHAMWHAM! The startled shooter has the presence of mind to keep the piece pointed downrange while myself and every other safety officer on-site sprinted to his side. It was pretty wild.
