What is the "right way" to install a clamp style gas block?
Are there any steps beyond applying a little red loctite and tightening the screws appropriately?
Do I need to get out the half inch drive breaker bar?![]()

I would send it off to Adco to have it permamently pinned in place.

When the Vltor clamp-on gas block/sight is installed correctly, the barrel index pin will shear before the gas block ever shifts on the barrel (over 100 ft/lbs of rotational torque).

However rotational torque is not the only issue at play -- direct impact with move a gasblock that is not pinned in.
I've had it happen.

Yup... I'm with Kev.. if it's not pinned.. It's not going on my barrel...
Gas block only has to screw up on me once..
But I know... the "Range Only" crowd say's that it's good enough and pinning is over kill..
In that case if your using it for that purpose, then it does not matter how you do it...
In my book there is no "Right Way" for a clamp cause I don't think the clamp itself is the right way...
Pinning a gas block is always a good idea. With that said, I feel that if you install a clamp GB (the way we do it) and the GB is sitting under a rail, it will never come loose.
We first degrease the barrel and GB. We then put green loctite on the gas port area. The GB screws are then degreased coated with rocksett and then torqued on with 50-60 inch lbs.
We have NEVER had a GB come loose or ever even shift on ANY weapon we have done.

Grant,
Thanks for the info.
I'm assuming it doesn't hurt to get loctite in the gas port because the gas will blow/burn it away.
Where can one purchase Rockset? I googled it and the only hit I got was in a thread in another firearm forum.
Well nobody is claiming that they can't be installed incorrectly and then later fail to take abuse. The detailed, supported claims I've seen provide far more useful information for decision making than, "I had one once and it didn't work." Nevertheless, the "tactical only" crowd is going to overgeneralize into blanket condemnation for every model and method. What ever keeps their confidence in their weapon up, I guess.
