Any advantages to a full auto BCG?

Palmetto has full auto BCG on sale for $99, marked down from $149. $99 is a solid price for a BCG anyday, but I'm wondering what's the difference from a semi auto only BCG? Advantages? Disadvantages?

Believe the only difference is full auto has more metal (and mass) than a semi auto BCG. The additional metal is used to trip the auto sear. They are not a regulated part and are GTG in semi-auto (so long as no other parts are full auto). As usual, I'm sure Mek has more insight about this.

yes. more mass = higher reliability always.
And also in this case more support at the back. Very small difference but it compounds to something.

Looks like aero has theirs for 109.99 this weekend too.
