Thanks TWR, that may work actually.
It appears that the Troy is a "free float" rail? I have a "standard" gas tube so I would need to mount a low profile gas block which shouldn't be to difficult and remove the front sight.
Depends - what barrel make and what type of pins?
The gas tube "size" makes no difference, it's the height/shape of the gas block that matters.
Also, not all "low profile" gas blocks will fit under a free float tube. The Troys rails are pretty generous, but the Noveske NSRs require the lowest profile gas block.
Do you have a delta ring installed? If so, you'll need to pull the barrel to get it off, or cut it away.
The Troy rail will mount to the existing barrel nut, which is nice.
