It's like insurance. I've had them come across the bench with and without. If it has them use them. Many of the single pin blocks just use a hollow roll pin so I use the set screws also though it would probably be fine without them.

Unlike taper pins, a few of the gas block that use spring pins can still have play and the set screws eliminate that. Some gas block manufacturers do not recommend using threadlocker on the set screws, and state that if you do use threadlocker, only use the blue. Over tightening the set screws can cause issues, especially on the light weight gas blocks. I would probably drive the pin first, then torque the set screws.

Some pin jobs don't hold the GB securely, there is still some movement.

I'd still use the screws with some Rocksett.

I've drilled/pinned a handful of LPGBs, I use a 3/16" roll pin. There is zero movement.
If I bought one that had movement I'd send that shit back. |
