Anyone use a Larue .750 gas block with a BCM SS410 18" barrel? When I slide it over the barrel it seems really loose. Does it tighten up right when installed? Hope this isn't a stupid question. This is my first complete build and I want it to be right. Thanks guys!

At the point where the port on the GB lines up with the port on the barrel, you should be able to turn the GB freely with your fingers but it's should not fall of the barrel under it's own weight.

At this point.


Hope this helps.

is the GB designed for the barrel profile?

Yep. According to BCM's website the barrel requires a .750 gas block.

Just screw that GB down, and you'll be fine. Some GB give more "slack" at the port, luckily the YHM unit happens to be just right for thet barrel.
