I thought I had read somewhere they changed the installation method because their military users wanted something easier to service?
Kevin Boland and some other Knights' guys post here so maybe one of them could chime in.

As long as the block is reasonably snug... drill dimples for screw engagement, a liberal application of loctite 638 on the block w/ red on the screws, then stake the snot out of the screws.
I've found rocksett to work extremely well to retain gas block screws, yet still allow reasonable removal.
Also, has there been any problem with the Syrac's gas block adjustment screw or other internal components after they get carboned up with long term use ?
Resurrecting this thread from the dead for hopefully pertinent reasons. :)
1. Has anyone found a place willing to pin a Syrac block or gotten ahold of Jason at Syrac to discuss the possibility of getting a block with a pre-drilled pin hole?
2. Is there any problem with attaching the Syrac set-screw block on a barrel that has already had material removed for a previous pinning? I just ordered one of Grant's new DD 16" Middie uppers with nitrided barrels, but the DD gas block is pinned. If I can't find some way to pin the Syrac on the barrel, I'll have to settle for simply set screwing it on. I don't know enough about the technical side of ARs to know if that's a problem or not.
Thanks everyone. :)
I'm running a few block with just the set screw... Including my syrac now. Dimple the barrel and rockset the screws and it seems fine. :confused:
Works for me! And it will be underneath a rail anyway, which seems to make the pinning unnecessary from what I gathered in this thread.
I just didn't know if there was a problem using set screws to hold a block onto a barrel that was previously pinned. I'm out of my league here when it comes to gas blocks.
I just recently did a Syrac gas block install and had my gunsmith pin it. Zero issues with pinning it.
The one thing I am concerned with is that I can't seem to close the gas port enough. I have a email out to Syrac to see if there is a fix.
That's awesome news on the pinning. Hopefully whoever works on my upper will be willing to do the same.
With regards to the gas block not closing as much as needed, how old is it? Syrac said that the first production blocks (mostly purchased before December, though some still lingered in the market into 2013) wouldn't completely shut off the gas if closed all the way, and the newer blocks supposedly have been fixed and should close as far as necessary to shut off all gas.
