URX II gas block, staked bcg (2 ?'s)

I just purchased a URX II, and was wondering if the larue low profile gas block will fit under. I have a DD carbine length pencil barrel. If that does not fit, which one will? I would like to not have to dremel out the rail to fit anything, unless there is no other option.

I have also read that the young mfg bcg does not come staked from their factory. But have also read that companies do stake them. Does anyone know if rainier does this, and if not a link or explanation to do this. Its going into a VLTOR MUR if that helps any.

Thanks for the help

It will fit. Larue’s lo pro gas block is one of the lowest, if not the lowest, profile gas block on the market.

Carrier keys are so easy to stake that I would not let staking be my deciding factor of whether I purchase or not. Price and other features mean more to me. I can stake one in a couple of minutes and so can you or anyone else with even the slightest mechanical aptitude.
