Thank you again Wash, Here is what I am looking at as a possibility:

Lowered gas blocks are all over the place, Is the gas port sealed in any way? I've yet to take it apart to see how it mates with the barrel in there.
At my age BUIS' aren't an option, therefore having a continuous "topline" on the weapon doesn't matter to me as much as having the extra hand guard length. This rifle will probably only punch paper and the occasional coyote. If, as they say, the TSHTF, there are plenty of more suitable options available to me. wink, wink.
