Will there be mechanical issues using a milspec safety with a semi auto trigger?

[okie]

I have a Colt milspec (3 position) safety from a SOPMOD kit, and I'm wondering if I will be able to use it with a semi auto trigger group, or if it will cause some unforeseen mechanical issues.

It will work but the safety will continue past the normal fire position on a semi rifle.

Right, but with a semi trigger group the third position will either be safe or semi, correct?

It will be safe in the third position unless you have an auto disconnector installed.

This.

Nope.

On semi it will fire.

Flipped 180 to where "AUTO" would normally be it'll fire in semiautomatic mode. Unless you have shitty disconnector timing there is no full-auto sear to release the hammer once the bolt is locked.

Olympic Arms sold metric ass-loads of AR rifles and carbines with GI selectors in the 80s and early 90s that would go past 90-degrees. New-old stock selectors eventually dried up as the assault rifle ban kicked-in in 1994.

This guy is correct.

Can confirm. It works perfectly in the third position as a semi auto, no difference whatsoever.

[Pappabear]

Should not be an issue.

I used that safety with a Geissele SSA in a Colt lower, had no issues for the few years I had it. I've since switched to Geissele safety for unrelated reasons.
