I just picked up an A-1 Light Barrel Carbine upper and noticed the front sight base was pinned in with roll pins. Aren't they usually done with tapered solid pins? Is this safe? Any help is much appreciated.

Yes, tapered pins.

No, the roll pins will work just fine, but may become loose over time and need to be replaced with the tapered pins.
If the front sight tower starts to have side to side movement, it's time to replace the pins to the tapered type.

Hope this helps.

Yes, thanks. I'll replace them anyway since I don't like the plastic delta ring. Thanks!
