Thread pitch on mag release

[Gitz]

Can anyone tell me what the thread pitch is that STI uses on their drilled mag release buttons/ I am guessing 6-32?

Be careful of large mag releases when firing weak hand , if the spring is light your left hand trigger finger may cause the mag to drop while firing. Try it a lot, weak hand after you install it to be confident with it.

i started to make myself one but for the 15 0r 20 dollars it's much easier just to buy one.and because it's an STI you want it to look good........
