One company used ONE set screw and no barrel dimple and CLAIM no issues. Well Igues for a range toy that gets rare use that may be the case but for a Duty - SHTF your life depends on it I will never use just a set screwed gas block. more than one professional trainer has commented on set screws loosening during extensive training classes.

I wish BCM pinned their low profile gas blocks (or at least offered the option). They told me that they have never had one single one of their gas blocks come lose. But they only use one dimple, not two. I’ve been thinking about buying they jig to pin it myself. Do you think I should do that?
@GunsandTactics6 жыл бұрын
Brad Steele I pin all of my serious use rifles and feel it’s the most secure. BCM uses high temp thread locker and no doubt that works very well. If your block is secured well and under a hand guard one could argue that it probably isn’t needed to be pinned. But pinning would only make it even more secure. Ultimately up to you -Dave

Brad Steele Ballistic Advantage offers gas block pinning. I’ve had really good results with my BA barrels in terms of accuracy. Even more accurate than the two BCM barrels I have. For my CHF, I use DD and dimple the barrel with a kit I got from....PRI I think. Maybe it was SLR, but allows me to dimple the barrel where the GB screws can seat into the dimple. Works well.
